64 Maintenance
Conventional fire detection control panel
15.3.2 Night
There are no people in the building, therefore, there is only one person in charge of building safety (e.g.:
night watchman, guard).
15.3.3 Changing Day/Night mode manually
From panel with access level 2:<key>, Settings
15.3.4 Changing Day/Night mode automatically
Setting up a timer (refer to paragraph 9.3 - Setting the Timers) to toggle the panel status.
15.4 Bypassing a zone
From panel with access level 2:<key>, Disablement, Zones, select a zone, Ok
Under certain circumstances (e.g. maintenance or fault), it may be necessary to bypass a zone. Bypassed
zones or points cannot generate fault or alarm signals and cannot be activated.
15.5 Bypass the DIALER or ALARM NAC output
From panel with access level 2:<key>, Disablement, Outputs, Ok
Under certain circumstances (e.g. maintenance or fault), it may be necessary to bypass the dialler
(paragraph 4.2 - [E]) or ALARM NAC outputs (paragraph 4.2 - [F]). The bypassed object cannot be
activated.
Bypass may be necessary in the event of fault signalling triggered by the dialler or supervised output (refer
to Chapter 16 - Diagnostics and fault solutions).
15.6 Testing the zones
From panel with the jumper inserted:<key>, Maintenance, Test zone, select a zone, Ok
Maintenance work often entails zone tests. Activation of an alarm when a line is in Test status will activate
the ALARM NAC output for approximately 3 seconds. The control panel will reset the line automatically
when the brief output signal ends. This feature allows the technician to test the system without the
assistance of another person.
Note:
The LED of detectors in test status will go on for several seconds, and the ALARM NAC will activate for 3
seconds to confirm reception of the alarm signal. The detector will reset automatically.
1. Press Ok to put the zone in test/operating status.
2. Press or to go to the adjacent zone.
15.7 Force the status of I/O lines configured as outputs
From panel with the jumper inserted:<key>, Maintenance, Test outputs, select a zone, Ok
In the event of maintenance or first power up, it may be necessary to activate manually the output of an I/
O line configured as an output.
Silence The Silence command holds off signalling. The Silence phase will run for the pre-set time. If
no-one intervenes during this phase, the system will undo the silence command and the
alarm will continue. To change the night-mode silence time, refer to paragraph 9.5 - Setting
the control panel options.
Pre-alarm The pre-alarm signal can be disabled on certain points. Alarm events will generate instant
alarms. Refer to paragraph 9.2.2 - Detection line parameters to enable/disable the pre-alarm
time on points during Night mode.
