APPENDIX A
DESCRIPTION OF ALARM ZONE TYPES
Different zone types can be selected using the programming mode. Each zone can be selected as any one of
the following:
Type Description Input Delay
1 Standard Latching 2 seconds
2 Standard Latching 2 seconds with AVF
3 Non Latching 2 seconds
4 Non Latching 20 seconds
5 Time Delay 10 seconds
6 Time Delay 20 seconds
7 Time Delay 30 seconds
8 Time Delay 40 seconds
9 Time Delay 50 seconds
10 Time Delay 60 seconds
LATCHING TYPE
Once an alarm condition is received from the detector, the alarm zone will start a timer, if after 2 seconds the
detector is still activated the alarm zone will register an alarm condition. Indicators will illuminate and alarm
functions are initiated immediately, unless zone is set as AVF - refer Appendix C. The alarm zone will remain
in alarm until manually reset.
A reset is performed by interrupting the power to the detector for 0.5 seconds and returning the alarm zone
back to its quiescent state. If an alarm is still present in the detector area, the detector will re-activate and the
2-second timer will be re-initiated.
NON LATCHING TYPE
A temporary actuation device (e.g. Flow Switch) is usually connected to this type of alarm zone. Once a
signal has been received CONTINUOUSLY for 2 seconds or 20 seconds (dependant on programming) an
alarm will be registered causing the alarm LED to flash and alarm functions will be performed as programmed.
The alarm group will remain in alarm until the actuating device no longer reports a signal. When actuating
device signal is clear, the alarm is cleared, causing the zone to power down for 0.5 seconds and return back to
normal state.
