Zone Input mode
This example shows how to set a channel as a Zone input.
Mode settings notes
Zone Input Zone Input Type
The Zone Input Type monitors 'conventional' detectors
and call points, with manual call points having 470
ohms resistor in series with Normally Open contacts.
When Gent detectors operate they will draw a constant
current of 30mA. A standard end-of-line capacitor
must be fitted across the Z+ and Z- terminals. Each
zone input can have up to 20 standard detectors
connected with the diode base option.
A Zone Input Type can accommodate a range of
different products to operate at different zone input
thresholds:
Gent (Type 0)
IS Esser Sensor (Type 1)
Apollo/Nittan (Type 2)
Tanlentum Flame (Type 3)
Det-tronics Flame (Type 4)
S/C Fire (Type 5)
Validation Delay
The purpose of the alarm Validation Delay is to
minimise false alarms. The alarm validation timeout can
be any value in the range 0 (off) to 37.5 seconds.
During alarm validation delay timeout period the
interface will suppress fire event by applying a reset to
the zone circuit and then wait for a second confirming
fire signal.
Reset Period
Other detector types may need a specific Reset period
which can be set here in seconds.
