Description

NOTE: Since egress from a magnetically locked door can be a
safety issue, make sure you are complying with local building
codes. Contact your building and/or fire prevention department.
The XMS2 is a passive infrared motion
detector specifically designed to release a
magnetic lock from the inside of an opening
for free egress. Unlike burglar alarm type
detectors, the XMS2 has special features
appropriate to this use. The lock control
function is fail safe so that the magnetic
lock will safely release if power is cut to the
detector. A relay is also present to send a
REX (request to exit) signal to an access
control system (if one is present) and
therefore shunt an alarm report. A time
extension feature avoids the problem of the
unit resetting if a person momentarily stops
moving just before an exit. Tight control of
the exit detection pattern allows maximum
security from the outside and avoidance
of inadvertent activation from the inside.

Physical Installation

NOTE: XMS2 is intended for indoor use only.
Fixing the unit to the wall:

1 LOCATE the screw on the end of the
unit to loosen it (Diagram 2).
This permits y ou to remove the cover.
NOTE: The appearance of the interior is
shown (Diagram 3).
NOTE: The interior electronic board is
mounted on a rotating barrel which is
locked by the “Barrel Locking Screw”.
2 LOOSEN the Barrel Locking
Screw and rotate the barrel fully
upward so that it can be removed
(Diagram 4 / Diagram 5).
3 Once the Barrel is removed you will
have the back bracket to use as a
template. You will see two slotted
holes for physical mounting of the rear
housing and a choice of two wire entry
points.
NOTE: Most Installers prefer to pull
the cable thorough the wall first and
them mount the bracket to the wall.
4 MOUNT the back bracket to the wall
using the hardware provided
(Diagram 6).
5 REPLACE the barrel assembly.
6 ATTACH the wires to the screw
terminals.
NOTE: Coverage with XMS2
is dependent on placement
of the unit (Diagram 7).

Placement of the Unit

NOTE: XMS2 is intended for indoor use only (Diagram 8).
Position the XMS2 with respect to the inside
of the door so that its detection pattern
will “see” a person approaching the door
while maintaining good security from the
outside. There are different options as to
where the unit is placed depending on
variables in the application (Diagram 8).
The simplest method of placing the unit
is for traffic control applications. A traffic
control application is one where you
do not expect any attempt at breaking
in from outside. The unit is simply
centrally positioned above the door
with the pattern covering the door.
For security applications, you will set
your position to defend against someone
activating the detector from the outside.
To deal with this threat, the unit is
positioned above and outside of the door
hinges with the pattern adjusted so that
it sweeps across the door but does not
detect the bottom of the door. If the door
includes an exit bar, the pattern must be
broad as a person’s approach to the door
is variable. If it includes a door knob or
lever handle, the pattern can be adjusted
more narrowly. A final option for security
applications is to position the unit at the
side of the door so that it sees across the
door. This can be used for doors at the end
of corridors. You would not want to employ
this approach for non corridor doors as
the door would be released by someone
walking near it (maximum detection
range is approximately 20 ft.) Side of door
mounting has the disadvantage of greater
exposure to vandalism but defends against
objects being inserted under the door and
provides excellence coverage along the
full width of the door . Note that for the
end-of-corridor application, the unit can
be positioned on the same wall plane as
the door or on a wall which is next to the
door and perpendicular to it. The pattern
can be adjusted a full 90 degrees with
respect to the sensor’s mounting plane.

Wiring

NOTE: Input voltage must match the required
voltage of the maglock being controlled.
To power the unit, filtered and regulated
DC Voltage between
12 and 24VDC should be applied to the
power input terminals (Diagram 9). This
connection should be permanently
made to the power supply and not
switched through another device. The
XMS2 should receive constant power.
Make sure you observe correct polarity
with this connection. If you reverse the
input power polarity, the unit will not be
damaged but will appear to be dead.

Wiring with a Magnetic Lock Only

This is the simplest application which
releases the magnetic lock from the inside
for free egress but is not concerned with
shunting any alarm point at the door.
NOTE: Positive power to the lock connects through
the terminal block “IN+” and “DEVICE”.
The IN+ and DEVICE terminals constitute
an internal field effect transistor which
does the actual switching (Diagram 10).
If the power to the XMS2 was somehow
interrupted, the field effect transistor
would automatically open, releasing
power to the lock. This function
makes the XMS2 “fail safe”.
NOTE: Never use the REX relay contact to switch the magnetic
lock. The REX contact only has enough capacity for signaling;
they cannot reliably switch magnetic lock current.

Diagram 9 XMS2 Overview

Diagram 10 Wiring Magnetic Lock Only

Wiring with a Controlled Entry Unit
Integrating a controlled entry unit such
as a digital keypad, would use a set of NC
contacts from the entry unit to break the
wire connection between DEVICE and
the magnetic lock + to allow the entry
unit to release the lock (Diagram 11).

Shunting and Alarm Point
This technique for installations where
the door is connected to an alarm system
and that if the door opens without
the XMS2 having been activated, an
alarm signal should result. When the
XMS2 is employed to open the door,
the alarm signal should be shunted.
The alarm system will be connected to a
door position switch or other detector
at the door via two wires. You will need
to determine if this loop is closed when
the door is closed and opens when the
door opens or is the opposite, open when
the door is closed and closed when the
door opens. Correct wiring to shunt
the alarm is shown for both instances
(Diagram 12 / Diagram 13). You utilize
the REX relay contacts for this shunting
while the lock control relay contacts
continue to release the magnetic lock.

Diagram 12 Alarm Signal Closed with Door Closed

Diagram 13 Alarm Signal Open with Door Closed

Integration with Access Control System
An access control system permits entry and
will also often act as an alarm system if a
door is forced. To integrate with the XMS2
and a magnetic lock, the access control
system should have a two terminal REX
(request to exit) input. When this input
is closed, the access control system will
operate its lock control relay to release the
lock and will not create an alarm signal as it
will consider the exit event an authorized
one. Wiring is shown (Diagram 14).
NOTE: With this wiring method, the lock control terminals of the
XMS2 directly break power to the magnetic lock as do the access
control system contacts. This is called double break wiring.
This wiring enhances safety and reliability
as if the access control system experiences
a fault, the XMS2 still allows safe egress.
If the access control system is not
monitoring the door, connection to the
REX input is not required. In that case
make all other connections as shown
(Diagram 14) except the REX input.
In some jurisdictions, the combination
of a magnetic lock, access control system
and Exit detector such as the XMS2
can be considered an access controlled
egress door. The applicable section of
the Life Safety Code calls for a redundant
means of exit in the event of a problem
with the detector. This is typically a push
button located 40–48 inches above the
floor and within five feet of the door.
Pushing the button will directly release
power to the magnetic lock and the lock
shall remain released for 30 seconds.
This can be accomplished with any of
the Securitron push buttons and the
TM-9 timer and EEB push button series
with integrated timers. The EEB series
is easy to use with the XMS2 to satisfy
code requirements with its factory set
30-second integrated timer, for access
controlled egress doors (Diagram 15).

Basic Operation

When the XMS2 is first powered its LED
will flash quickly twice every second for
about 30 seconds. This is a self test and
permits the XMS2 to adjust itself to the
thermal environment that it sees. After
this start up period the LED will stay
green. If the self test fails during the start
up period, the LED will begin to flash 4
times per second. This failure indication
will continue indefinitely. If this failure
indication occurs un-power the unit for 30
seconds and re-power the unit. During the
self test period the unit’s control outputs
are in their normal conditions (lock control
conducting, REX relay de-energized).
NOTE: If the failure indication occurs again after cycling power
please contact the factory for a RMA replacement of the unit.
In the event of a very brief power outage,
the unit will not self test for 30 seconds
but will undergo a self test of 10 seconds
before resuming normal operation.
NOTE: The self test on power up feature of the unit
is why the XMS2 must receive constant power.
Once the unit passes its self test, it will
be able to detect moving objects that
are a different temperature than the
ambient. With jumpers in the factory set
configuration, it will signal this detection
by switching its LED from green to red.
NOTE: The LED mirrors the state of the REX relay
rather than the lock control transistor.
You need to understand how the XMS2’s
control outputs operate in a detection
event. In the rest condition (green LED on;
no detection), the lock control transistor
is conducting and the REX relay is deenergized.
When an object is detected, the
REX relay energizes immediately. This is to
shunt alarm contacts or send a REX signal to
an access control system. Fifty milliseconds
later, the lock control transistor switches off
which releases the magnetic lock. The brief
delay is to make sure that the access control
system has processed the REX signal so that
it wont alarm if it is also reading lock status
detection such as the Securitron Bondstat
feature. A lock status signal will change
state as soon as the lock is de-powered.
The REX relay will remain energized as long
as the lock control transistor is continuing
to release the lock. When the lock resecures,
the REX relay will remain energized
for an additional second to allow the
magnetic lock to fully engage and report
secure in the event that it is reporting
lock status to an access control system.
In the factory set condition, the lock control
transistor will remain off for 4 seconds
after detection has ceased (keeping the
lock released). If, during the 4 seconds,
the object moves again, the detection
condition will be maintained for another 4
seconds after this “new” detection ceases.
For the magnetic lock to re-secure,
4 seconds must pass with no detection,
this trailing edge timing feature is for
egress safety and reliability. Otherwise, it
would be possible for a person to approach
the door, activating the XMS2, but then
stop moving for a brief moment at the
door. The detector would reset and if the
person quickly lunged into the door they
the movement could be quicker than the
detection response to the movement
and the door would not open as quick as
the person moving into it. The 4 second
trailing edge timing feature virtually
eliminates this potential issue. Another
operational safety feature is the fact that
if proper power is cut to the XMS2, the
lock safely releases so that a person is
not trapped. This trailing edge timer of
4 seconds can be reconfigured using the
jumper setting on the board of the XMS2.

Jumper Settings
The XMS2 has 3 jumper settings
that control LED logic, timing
logic, and sensitivity.
The LED logic jumper controls the logic of
the bi-color LED. When left in the factory
set position, (jumper installed) the LED
will illuminate red during a detection
event and return to green in the resting
condition. Removing the jumper will
reverse the colors noted in the above logic.
The Sensitivity jumper makes the unit
sensitive to movement in the factory set
condition (jumper installed). Removing
the jumper will decrease the sensitivity.
The Time-Set jumper can be installed
in any of three positions to alter
the factory set trailing edge delay
of 4 seconds. The diagram to the
right shows the three choices.
When setting the time set jumper 4
seconds is right for most applications,
a 1/2 second would be used for pattern
set up and certain applications where an
external timer should replace the XMS2
timer. For example, when the XMS2 is
integrated with an access control system,
the XMS2’s REX relay will trigger the
access system’s lock control relay and the
magnetic lock will release for the same
amount of time that is programmed for
entry. If the time-set jumper is installed
for the 1/2 second setting and assuming
a person is initially sensed by the XMS2,
Then does not immediately exit but moves
around the front of the door, they will
continue to retrip the XMS2. Persistent
retripping of the XMS2 however, will cause
the Lock Control and REX Relay to remain
latched until no movement is sensed for
a time greater than the set 1/2 second.
It is important to note that this device
has a“trailing edge” delay—i.e. the device
Lock Control and REX Relay will remain
latched until a time greater than the set
time has expired since the last detected
movement. The XMS2, when integrated
with an access controls system, is best set
at a 1/2 second timing. If the XMS2 is set
at 4 seconds the following may occur on
initial release. The access system would
start timing for 10 seconds (as an example),
but the person does not immediately exit
the door and instead moves around in
front of the door so the XMS2 signal does
not change and stays closed due to the 4
second timing function, if the door is then
used, a forced door alarm signal will result.
Another application where you should
employ the 1/2 second setting is when
the XMS2 is employed to initiate
delayed exit when you are using a
Securitron model XDT timer.
The 8 second setting is rarely used unless
there is strong concern for maximum
time being allocated for egress even when
movement is not maintained. The problem
with an 8 second trailing edge delay is that
entry security begins to be compromised.

Diagram 16 Time Set Jumper

Detection Pattern Set-Up

At this point in the installation, the unit
should be physically mounted and wired.
You should have also considered changing
the jumper settings. Your final step is
to adjust the detection pattern for the
optimum combination of egress safety and
entry security. Before doing this, set the
time set jumper to the 1/2 second position
(shown in the drawing to the right). As you
are adjusting the pattern, you will make
many quick tests of the unit and this will be
most efficient if you don’t have to wait for a
4 or 8 second trailing edge timer to expire.
The XMS2 provides two means of
adjustment. First, the entire barrel assembly
rotates 90 degrees so that the unit can look
“out” or “down”. Second, aiming screws are
provided to laterally control the pattern.
To access the aiming screws, the barrel
assembly must be rotated so that the unit
looks “out” so while you are making these
adjustments, you will need the barrel
locking screw to be loose (see Diagram 4).
In most applications, the unit is set to look
“down”. The exception would be if the
XMS2 was mounted on a wall perpendicular
to the door rather than parallel to it. As the
detection pattern proceeds outward from
the XMS2 it spreads in the same direction
as the barrel rotates rather than lateral
spreading which is constrained by the
aiming screws. The drawing on the right
provides an example of this spreading.
Assuming the XMS2 is mounted seven
feet above the floor, the pattern will
spread out roughly three feet by the time
it reaches the floor. Maximum detection
distance is approximately 20 feet.
The aiming screws control internal
louvers that point the same way as the
slots in the screws. When adjusting
these screws,do not turn them past
the point where you feel resistance as
they can take the louvers “off track”.
Diagram 18 shows the typical relationship
between the aiming screw orientation
and the resultant detection pattern.
To set your pattern laterally, experiment
with the aiming screws as is shown in
Diagram 18. Each time you alter the aiming
screw setting, you will have to rotate the
barrel assembly up and down. Test the
pattern by moving in it and observing the
limits of detection by watching the LED.
When you are satisfied with the aiming
screw settings, you must also finalize the
degree of barrel assembly rotation. You
don’t want the unit “seeing” the surface
of the door itself as this can lead to false
detection, so in the common case where
the unit mounts in the same plane as
the door, you do not want the barrel
assembly adjusted at full 90 degrees. It
should face slightly away from the door.
When you are entirely satisfied, be
sure to tighten the barrel locking
screw and restore the time set
jumper to the 4 second position (if
necessary). Then replace the cover.

Troubleshooting a XMS2

PROBLEM	SOLUTIONS
XMS2 does not power up.	• Using a volt meter, confirm voltage is 12–24 VDC.
XMS2 LED flashes after release.	• This is because power is being dropped to the XMS2 and Constant voltage should be supplied to + and – terminals. • Verify Voltage
XMS2 LED changes but does not drop voltage.	• Verify the positive voltage is going to the IN+ terminal and out the DEV terminal. Reversing this can cause this effect.
XMS2 does not register when a person approaches the opening.	• Verify the XMS2 barrel is aiming towards the point where it would pick up an approaching person and also verify the aiming screws are set up correctly and are open.
