•
The alarm current provided by zone 8 will support 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.
Wiring 2-wire Glassbreak Detectors
To wire 2-wire glassbreak detectors, perform the following steps:
Step Action
Select from the list compatible 2-wire latching glassbreak detectors.
2 Connect detectors across zone 8 (terminals 21 and 22). See Figure 6-4.
3 Connect the EOL resistor across the loop wires at the last detector.
