Initiating Zone Description
This allows the user to describe the initiating zones. Ten different descriptions are available. They are:
1) FIRECYCLE - Used only with Normally Closed Firecycle
®
heat detectors. Automatic restoration of the Firecycle
®
heat
detector will automatically start the Soak Timer.
2) DETECTION - These include smoke detectors, pull stations, heat detectors and other devices put on a conventional zone.
3) WATERFLOW - Alarms from waterfl ow zones are non-silenceable
4) LINEAR HEAT DETECTION - These use a special wire with a fuseable insulation
5) MANUAL RELEASE - Used to override cross zoning and cause instant release
6) LOW AIR ALARM – This is for a low air switch used in a double interlock system. Usually cross zoned with a smoke or heat
detector. Activation of this zone creates a supervisory condition on the panel but can still operate the release circuit.
7) SUPERVISORY - For monitoring any supervisory function as assigned
8) TAMPER - For control valve monitoring
9) LOW AIR - Used to detect low air pressure
10) HIGH AIR - Used to detect high air pressure
The fi rst fi ve descriptions (FIRECYCLE, DETECTION, WATERFLOW, LINEAR HEAT DETECTION, and MANUAL
RELEASE) are Alarm Zones. When activated, they will put the panel into alarm and operate the appropriate output as well as
operating the alarm relay.
The 6
th
description (LOW AIR ALARM) creates a supervisory condition on the panel but can be used to activate the release
circuit. This activates the Supervisory relay not the Alarm relay.
The last four descriptions (SUPERVISORY, TAMPER, LOW AIR and HIGH AIR) are Supervisory Zones. When
activated, they will put the panel in a supervisory condition and activate any output described as “SUPERVISORY BELL”. They
cannot activate the release circuit.
The 1st description (FIRECYCLE) is an automatically resettable alarm zone. The status of the zone follows the status of the
FIRECYCLE heat detector. When the detector restores, the zone restores and initiates the soak timer.
Note: When FIRECYCLE is selected for zone 1, only outputs #3 and #4 can be mapped as releasing circuits.
If zone 1 is programmed as the FIRECYCLE, the following will appear in the display:
