The digit controls are:
1 Relay 1 added/removed from the zone’s control
2 Relay 2 added/removed from the zone’s control
3 Relay 3 added/removed from the zone’s control
4 Horn added/removed from the zone’s control
5 Strobe added/removed from the zone’s control
When controlled by a zone the default horn pattern is the Triple Tap pattern, see 3.3.7.7 and the strobe will turn on continuously when a zone is controlling them.
Each zone can have up to three control groups defined. Each group either monitors a sensor type or implements a timer function.
3.3.7.2 Zone Group Type
Figure 3-43 Zone Group Type
This display example shows that group 1 in zone 1 will be monitoring Nitrogen Dioxide sensors. The valid Types are:
0 Timed
1 Carbon Monoxide (CO)
2 Nitrogen Dioxide (NO2)
3 Combustible(EX)
The default Types are:
- Group 1 in each zone is Type 1, i.e. monitors CO sensors
- Group 2 in each zone is Type 2, i.e. monitors NO2 sensors
- Group3ineachzoneisType3,i.e.monitorsEXsensors
Timed mode turns the zone’s outputs on at the START TIME if the current day is a weekday (or a weekend) and turns them off at the next occurrence of STOP TIME. The other three modes
