4. Controls Via Keypad
Keypad keys, are activated only when the key of the Keyswitch is set in the Control
Enable position.
4.1 System SILENCE key
Pressing the
SILENCE
key will cause any existing audible signal to stop. If a
new event occurs, the silenced condition will be canceled and the appropriate
devices will resound.
4.2 System TEST key
By pressing the
System TEST
key all the visual indicators of the keypad turn
ON, confirming that none of the LEDs are damaged. The condition is main
-
tained for as long as the
System TEST
key is kept pressed. The buzzer and the
main sounders are also active during the test.
4.3 System RESET key
The
System RESET
key is used for resetting the system’s zones in Standby
mode after an alarm.
4.4 Zones BYPASS keys
(also called zone disablements)
The
Zones BYPASS
keys are used to prevent the corresponding zone from causing
an alarm. Note that zone disablements must not be a permanent working condition and
they must be used only as a temporary action. For example zone bypassing can be used
in case of building maintenance or other activities that can trigger false alarms on the
detectors.
Bypassing a zone is achieved by positioning the keyswitch in the
Control Enable
posi-
tion and then pressing the corresponding
Zones BYPASS
key. At the same time
the indicator is turned ON. It only returns to normal operation by pressing the
same key again (toggle action). If one of the
Zones BYPASS
key indicators is
turned ON (yellow color) the corresponding zone is isolated and does not cause
alarms. If an error occurs to a bypassed zone, the
General FAULT
indicator is
activated but the system stays in silent mode. An alarm condition to a bypassed
zone is recognized and indicated but do not activate the sounders.
If any of the zones is in bypass state the buzzer sounds every 1 minute to re-
mind the user of the existing disablement.
