screen or abort the wizard. The Down
and Up
buttons are used to alter a selection.
The Continue
button accepts the current selection
and continues to the next step of the wizard.
Wizards are available for Zero and Calibration menus in
Supervisor menu.
3.6 Inhibiting channels
Inputs can be temporarily inhibited so as not to cause
alarms. This may be necessary when calibrating
detectors, or when operations are carried out close
to a sensor which may trigger an alarm (for example,
soldering near a smoke detector). Input channels can be
inhibited individually or all at once. The ‘inhibit’ option is
available in the Supervisor Menu, see the Menu System
Overview on page 23 for details on how to access this
function.
When inhibited Gasmaster will:
■
Display the ‘inhibit’ symbol
on the channel
display for each affected channel.
■
Illuminate the yellow ‘Warning’ LED.
In the event of an alarm on an inhibited channel,
Gasmaster will:
■
Illuminate the Alarm symbol on the channel
display for the affected channel.
■
Illuminate the red alarm LED bar.
■
Display the alarm text message for the affected
channel.
Gasmaster will not:
■
Operate any relays associated with the affected
channel.
■
Drive external audible visual alarms.
■
Activate the internal sounder.
If it is necessary to permanently disable a channel, enter
Supervisor Mode and set the relevant detector Type
to Unused (see section 3.10 on page 23). The channel
display will then blank, and the power supply will be
removed from the detector.
