16.3
Operational Features
•
The Fire Alarm Control Panel has a number of optional features. The definition and operating characteristics
of these features are described below.
16.3.1
Output to fire alarm devices:
•
It is possible to silence the fire alarm devices at access level 2
•
Following silencing, it is possible to re-sound the fire alarm devices at access level 2.
16.3.2
Delays to Outputs:
•
The operation of delays to fire alarm devices is selected at User Level 3 and applies to:
-
fire detectors
-
manual call points
-
signals from specific zones.
•
The delay times are configurable at User Level 3 and can be adjusted in 10-second increments up to a
maximum delay of 10 minutes.
•
It is possible to override these delays.
•
The delay to one output signal does not affect the action of the other outputs.
16.3.3
Coincidence Detection:
•
The fire alarm control panel can inhibit the output to fire alarm devices until two or more signals are received
from detection points operating within the same zone.
•
When programmed to operate in this manner the following applies:
-
It can only be selected at User Level 3.
•
Inhibiting the programmed fire alarm output signal in this manner does not affect the action of any other
outputs.
16.3.4
Fault Signals from points:
The control panel can receive & process fault signals from points, under these conditions the faults are indicated
as zone faults.
16.3.5
Disablement of addressable points:
•
The control panel has the facility to disable / enable signals from addressable points at User Level 2, either
individually or by complete zones.
•
Each device disabled in this manner is identified at User Level 1 and zone disablement's are only indicated
as such, when all devices within that zone are disabled.
16.3.6
Test condition:
•
A test facility exists, in which the user, at User Level 2, can test the operation of fire alarm detectors. When
testing the fire alarm system in this manner, the following conditions apply:
-
The control panel is in a test condition and indicates such, when one or more zones are in test.
-
The test mode can only be entered or canceled by manual operation at User Levels 2 or 3
-
It is possible to test the operation of each zone on an individual basis.
-
Zones in a test state do not prevent the mandatory indications or outputs from zones, which are not in a
test state.
-
Signals from a zone under test do not lead to the operation of outputs to fire alarm devices, except for
short periods, during which the device function can be tested in relation to the zone under test.
