Figure 4-68 Zone Controls
This display example shows that Zone 1 is configured to control all of the relays plus the horn and the strobe. Each of
the relays, the horn, and the strobe can be removed from (or added to) the zones control by pressing the indicated
digit key. By default, Zone 1 will control Relay 1, Zone 2 will control Relay 2 and Zone 3 will control Relay 3.
Definitions:
•
Zone – Defines Sensor Input & Relay / Alarm Output
•
Group – Set of Sensors of the same type and output within the same zone
•
Average – Activation based upon an average of sensors in a group
•
Voting – Number of sensors needed to be above trip point to activate the output
•
Quorum – Number of sensors need to vote, 1 = any sensor
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 section
, 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.

Figure 4-69 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 (NO
2
)
The default Types are:
•
Group 1 in each zone Type 1 CO, Voting mode, Quorum = 1
•
Group 2 in each zone Type 2 NO2, Voting mode, Quorum = 1
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 turn the outputs on if the gas concentration
indicated by that type of sensor is at or above the Rising Trip Point and turns the outputs off if the concentration is
less than or equal to the Falling Trip Point.
