2 Use and Operation
System
The system is controlled by a
processor with a software that monitors and ensures system’s
security, which increases its reliability
.
System access is restricted by password or keyswitch (level 2).
Front indicator leds and buzzer show the current state of the system.
The NFS Supra control panel has 10 system status leds indicators, zonal led indicators (alarm and
fault/disable/test), zonal push-button (disable/test/enable zone) and 6 function push-button.
Alarm zones
NFS Supra control panels have 4, 8 and 12 detection zones. Up to 32 sensors (System Sensor
Series 800 / ECO1000)
and/or manual call points may be connected to each zone
The control panel differentiates between an alarm from a sensor and from a call point.
Detector
Alarm
: Zone LED in flashing mode / Call Point Alarm: Zone LED in steady mode
The operation of each zone can be configured as:
-Normal zone: Immediate activation of alarms.
-Confirmed delay zone: The alarm must keep activated for 30 sec. (Not applicable
to detectors).
-Verified zone: The zone is reset in the first alarm and keeps monitoring for 10 min.
If a new alarm is generated within the verification time (10 minutes), the alarm is
confirmed. Otherwise, the process is reset without indicating alarm.
A short circuit in any zone maybe configured to be detected as an alarm or fault
(EN54/2).
