IMPORTANT: When using 4-wire smoke detectors with this device, the smoke detectors must be powered from a source other than the release device, such as an approved UL 1481 regulated power supply providing battery backup support.
OR
Relay Module Installation
In lieu of smoke detectors, the release device may be put into alarm by the fire alarm control panel. Most commonly, a relay module is used as an interface between the fire alarm control panel and the release device. The relay module must provide Form C dry contacts for connection to the appropriate terminals on the release device (Figure 7).
NOTE: When choosing a relay module to activate the release device in an alarm condition, always select one that provides Form C dry contact relays. Do not use any relay module providing or passing any (control) voltage through the contacts into the release device. The passage of voltage through such a relay module into the release device will cause problems with the operation of the device and may damage the device's terminals and/or circuit board.
Figure 7: Diagram showing Relay Module connections. A 'Relay Module' has 'Common' and 'Normally Closed' contacts. 'Red' wire connects to 'Common' and 'Black' wire connects to 'Normally Closed' on the 'Fire Alarm Control Panel'. These connections are made to terminals 5 and 6 on the release device's terminal strip.
OPTIONAL CONNECTIONS
CLOSE DOOR DETECTION OPTION
Connect wiring from N/O electrical loop, using a proximity switch or other similar device with dry contacts, to 7 and 8 (Figure 8). The switch should be placed to engage when the door is in the closed position and so that it will toggle states from its N/O condition (switch closed when door is closed) to a closed condition indicating that the door edge has made contact with desired down position. When the switch is closed by contact from the door, the release device will not activate on alarm, thereby eliminating nuisance gravity drops through the inadvertent release of the fusible link assembly. This option only works as long as power is available to unit. Fail-safe operation is maintained under all operating conditions, and if power is not available to the unit, the fusible link assembly will be released. This is a power-limited, unsupervised circuit. This proximity switch must be mounted in the same room as the release device.
Figure 8: Diagram showing connections for the Close Door Detection Option. Terminal 7 connects to 'Attach to Common on N/O Proximity Switch' and Terminal 8 connects to 'Attach to N/O Position on Proximity Switch'. A 'Proximity Switch Part No. LM56A' is indicated.
RELAY AND TROUBLE OUTPUTS OPTION
Connect wiring from the Alarm Relay Outputs (#11 N/C or #13 N/O and #14 Common) to the appropriate inputs on the fire alarm control panel to provide a signal at the panel when the release device is in an alarm state. Connect wiring from the Trouble Relay Outputs (#14 N/C or #16 N/O and #15 Common) to the appropriate inputs on the fire alarm control panel to provide a signal at the panel that the release device is in a trouble state (Figure 9). If these features are desired, coordinate the interconnection between the Release Device and the Fire Alarm Control Panel with the fire alarm installer.
Figure 9: Diagram showing Relay and Trouble Output connections. Terminals 11, 12, 13 are for 'N/C Alarm Relay Output', 'Common', and 'N/O Alarm Relay Output' respectively. Terminals 14, 15, 16 are for 'N/C Trouble Output', 'Trouble Common', and 'N/O Trouble Output' respectively. These connections are made to the Fire Alarm Panel as required by project specifications and Authority Having Jurisdiction.
ANNUNCIATOR OPTION
To power one or two (maximum) horn/strobes or similar annunciators, connect wiring to terminals 9 and 10 (Figure 10). Route wires through the non-conductive sleeving (provided) covering any exposed bare wires. Maximum distance of wire run within conduit not to exceed 20' total This is a supervised, non power-limited circuit.
NOTE: If installing two visual annunciators, they must be installed on opposite sides of wall.
Figure 10: Diagram showing Annunciator connections. Terminals 9 and 10 are connected to 'Horn/Strobe' units. A 'Non-conductive sleeve' is indicated for wire routing. A 10k Ohm @ 1/2 watt Supervisory Resistor (LMEOLRES-10) is shown in the circuit. The diagram notes that a maximum of two annunciators may be installed.
VOICE BOARD OPTION
The voice board provides one of two verbal warnings that the fire door is closing. Typically, depending on the length of the delay chosen on the release device, a warning tone will occur prior to the message, which is approximately 10 seconds in length (for example, a 20 second delay setting on the release device will result in a 10 second warning tone followed by the verbal warning message). There are two messages that may be selected:
- Message 1: Warning tone followed by the message, “Warning! An emergency condition exists and this fire door is about to close; please remove any obstructions from its path and stand clear."
- Message 2: Warning tone followed by the message, “Warning! This fire door will close in 10 seconds... 5 seconds... the fire door is now closing; please remove any obstructions from its path and stand clear."
The release device has an 4-position DIP Switch mounted on the circuit board, and the switch at position #3 permits selection of either message. In the “ON” position, Message 1 is activated; in the "OFF" position, Message 2 is activated.
The voice board can drive up to two 70.7V speakers (Model LM8SP) or speaker inputs to speaker strobes (Model LMPSTR2475ADA). Maximum delivered power is 5 watts.
A potentiometer (VR1) is mounted on the board and rotation counterclockwise increases the volume (clockwise to decrease volume) (Figure 11).
Figure 11: Diagram showing the 'Volume Control' potentiometer (CCW for Max volume) and 'Wire to Speaker' connections on the voice board.
DIP SWITCH SELECTION
The release device will provide a factory default delay of 10 seconds (to minimize nuisance alarms) before releasing the fusible link chain upon alarm or power loss. A 4-position DIP Switch found on the PC board within the release device can be used to adjust the length of the delay to one of four preset delays. The optional delay settings are as follows:
Figure 12: Diagram of a 4-position DIP Switch. The default setting shows all switches in the OFF position, corresponding to a 10-second delay. NOTE: Position 4 is unused and should remain in the OFF position. Position 3 is used to select one of the two available voice messages.
| Delay Setting | Switch Position |
|---|
| 1 | 2 | 3 | 4 |
|---|
| 10 Seconds | Off | Off | Off | Off |
| 20 Seconds | Off | On | Off | Off |
| 30 Seconds | On | Off | Off | Off |
| 60 Seconds | On | On | Off | Off |
NOTE: Set all DIP switch options before applying power to the system.
MAINTENANCE
▲ ▲ WARNING
To avoid SERIOUS PERSONAL INJURY or DEATH from electrocution, disconnect ALL electric and battery power BEFORE performing ANY maintenance.
MAINTENANCE REQUIREMENTS
The release device has no scheduled maintenance requirements. The unit has been designed and tested for use in dry, indoor locations. Testing of the unit at least once every 90 days is recommended, but test intervals shall ultimately be subject to criteria established by the Authority Having Jurisdiction (AHJ).
FUSE REPLACEMENT PROCEDURE AND REPAIR PARTS
One serviceable fuse, a 3 Amp, 3AG, slo-blo fuse, is required for proper operation and protection of the circuit board. The release device is shipped with the fuse in place and two replacement fuses are provided in a separate parts bag. The fuse is located on the circuit board near the battery cable connection.
Refer to page 13 for replacement parts.
BATTERY MAINTENANCE/TESTING
No maintenance or testing is required for the battery. An audible warning tone, generated by the trouble annunciator mounted to the side of the release device, will sound when the battery is approaching the minimum operating threshold. This indicates the need to replace the battery.
Refer to page 13 for replacement parts.
BATTERY DISPOSAL
Spent batteries must be treated as hazardous waste and disposed of in accordance with State, Local and Federal Regulations.
Figure 1: A diagram showing the front of the release device with a 'Mechanical Reset Plunger' on top and an 'End Link' extending from the side. The 'Electronic Reset Button' and 'Test Button' are located on the bottom of the release device, along with three LEDs: Red (Line Power Present), Green (Battery Backup Power Present), and Yellow (Close Door Detection/Release Disabled).
ENCLOSURE MOUNTED LEDS STATUS INDICATORS
| LED Label | LED Color | Description | Action Required |
|---|
| Battery | Green | If the Green LED is lit, then the battery is connected properly and charged above the minimum acceptable level. | If the LED does not light, check that the leads are connected to the battery as shown on the wiring diagram on page 6 of this manual. |
| Disable | Yellow | The Yellow LED will light when the door reaches the close limit and activates a proximity switch attached to terminal positions 7 and 8 on the release device. This configuration results in the device not releasing the fusible link assembly in alarm or power loss situations and should only be used when the fire door is kept in a constant closed position. | If the LED does not light when the door reaches the close limit and activates the proximity switch, then check that the proximity switch has been activated and that the switch is set to normally open (N.O.). Check to make certain that the switch is attached to terminal positions 7 and 8 on the release device. |
| Power | Red | If the Red LED is lit, then the line power is connected and switched "on." | If the LED does not light when power is applied, check that power is connected as described in the installation manual electrical connections. |
