866 Style W Notification Module

Installation Guide

DESCRIPTION

The 866 Notification Module provides one 5 Amp Style W notification circuit for supervising listed, polarized notification devices such as bells, strobes, and horns.

Compatibility

XT30/XT50 Series panels
XR150/XR550 Series panels

What is Included?

One 866 NAC Module
One Model 308 10k Ohm Resistor with Leads
Hardware Pack

MOUNT THE MODULE

The module can be mounted in a DMP enclosure using the standard 3-hole mounting pattern. Refer to Figure 2 as needed during installation.

Hold the plastic standoffs against the inside of the enclosure side wall.
Insert the included Phillips head screws from the outside of the enclosure into the standoffs. Tighten the screws.
Carefully snap the module onto the standoffs.

WIRE THE MODULE

Caution: Disconnect all power from the panel before wiring the module. Failure to do so may result in equipment damage or personal injury.

For power connections, use 22 AWG or larger wire. Refer to Figure 3 when wiring the module.

Connect module Terminal 1 to panel Terminal 7.
Connect module Terminal 2 to panel Terminal 10.
Connect module Terminal 3 to panel Terminal 5.
Wire power supply positive to module Terminal 4.
Connect module Terminal 5 to bell output positive.
Connect module Terminal 6 to bell output negative.
Install the included 10k Ohm EOL resistor across module Terminals 5 and 6.
Wire module Terminals 7 and 8 to N/C trouble contacts.

ADDITIONAL INFORMATION

Wiring Specifications

DMP recommends using 18 or 22 AWG for all LX-Bus and Keypad Bus connections. The maximum wire distance between any module and the DMP Keypad Bus or LX-Bus circuit is 1,000 feet. To increase the wiring distance, install an auxiliary power supply, such as a DMP Model 505-12. Maximum voltage drop between a panel or auxiliary power supply and any device is 2.0 VDC. If the voltage at any device is less than the required level, add an auxiliary power supply at the end of the circuit.

To maintain auxiliary power integrity when using 22-gauge wire on Keypad Bus circuits, do not exceed 500 feet. When using 18-gauge wire, do not exceed 1,000 feet. Maximum distance for any bus circuit is 2,500 feet regardless of wire gauge. Each 2,500 foot bus circuit supports a maximum of 40 LX-Bus devices.

For additional information refer to the LX-Bus/Keypad Bus Wiring Application Note (LT-2031) and the 710 Bus Splitter/Repeater Module Installation Guide (LT-0310).

Programming

Program the trouble contacts on the module and the auxiliary power supply as a Supervisory Zone (SV) selected for display in the keypad status list. Refer to the appropriate panel programming guide for more information.

Auxiliary Power Supply Supervision

The panel supervises the regulated, power limited auxiliary power supply listed for Fire Protective Signals through the normally closed trouble contacts on the power supply. The power supply trouble contacts connect to module Terminals 7 and 8 to the zone input from the panel. When the bell circuit is in a bad condition, these terminals provide an open condition to the zone. These trouble contacts are rated for up to 2 Amps at 30 VDC resistive. An open circuit causes an open condition to be reported to the panel. For wiring information, refer to Figure 3.

Bell Silence Toggle

A bell silence toggle prevents the indicating device from sounding during a system test. When the Bell Silence position is selected, a 15-second delay occurs before the module bell trouble contacts open. After testing, return the bell silence switch to the Normal position to return the module to normal operation.
