Figure 3-12. Wiring Latching Glassbreaks to Zone 8
•
The alarm current provided by zone 8 supports only one glassbreak detector in the alarmed state.
•
Do not use other N.O. or N.C. contacts when using glassbreak detectors on zone 8. Other contacts may
prevent proper glassbreak detector operation.
To wire 2-wire latching glassbreak detectors to zone 8, perform the following steps:
Step Action
1 Select compatible 2-wire glassbreak detectors that meet the requirements stated previously.
2 Connect detectors across zone 8 (terminals 27 and 28). See Figure 3-12 .
3 Connect the EOL resistor at the last detector in the loop across the zone’s terminals. You must connect the
EOL resistor across the loop wires at the last detector .
Tamper Supervision for the Hardwired Zones
The system can be programmed to monitor for either an open condition or a short condition of a tamper switch on zones
1-8. End-of-line supervision is required for this option.
Wiring a Tamper Switch to Zones 1-8
The wiring of the tamper switch depends on whether the tamper switch and the sensor are normally open or normally
closed.
•
If you are using a normally closed sensor, the tamper switch must be normally open. Refer to Figure 3-13 for
the wiring configuration.
•
If you are using a normally open sensor, the tamper switch must be normally closed. Refer to Figure 3-14 for
the wiring configuration.
To wire a tamper switch on a hardwired zone, connect the EOL resistor at the last detector in the loop across the zone’s
terminals.
You must connect the EOL resistor at the last detector for proper operation of the tamper
supervision.
NOTE: For the normally closed sensor , program the zone for trouble on short. For the normally open sensor ,
program the zone for trouble on open.
NOTE: For zones with a response type of 9 or 16 (Fire), the tamper selection must be “0” none.
