Panel`s Monitored Inputs for field devices
When an input is disabled, the panel will not respond to any fault or fire signals it receives from that
input. When an output is disabled, the panel will not activate that output.
This might be used if the system requires routine maintenance, and the customer needs the system to
continue running, but doesn’t want spurious false alarms or fault signals.
The panel will respond in the usual manner to any events in any non-disabled inputs.
To Programme an Input or Output as Disabled
Any number of inputs or outputs can be disabled, but it is good practice to only disable the minimum
requirement at a time.
Insert and turn control key to enabled position;
Press DISABLE button and the GENERAL DISABLEMENT LED will come on (flashing fast, 4 flashes
then off, repeated);
Press SELECT button. The GENERAL DISABLEMENT LED will light steady, and the Crossed Zone 1
Disabled LED will flash 4 quick flashes & off. The panel is now in SELECT DISABLEMENT MODE.
The select button is used to highlight (flash) the section that needs to be disabled. Press select button
until the correct LED is flashing, then press confirm. The LED will now flash 4 quick flashes & on, to
indicate that this section is disabled.
If more than one section needs to be disabled, then press SELECT button again until the required
zone is selected. (The previously disabled section will now have its disabled LED lit steady.)
If the panel needs to be taken out of SELECT DISABLEMENT MODE (eg to silence a fault on another
part of the system), turn the keyswitch off, then back on again.
Once all the work has been done the zones need to be enabled again. If the panel is not in SELECT
DISABLEMENT MODE, turn the keyswitch to controls enabled, press DISABLE button.
Press the scroll button until the disabled section has been selected. Press CONFIRM button to re-
enable. Scroll to any other disabled section and enable in the same way. When all sections are
enabled again, turn the keyswitch to off to return the system to normal.
