Failure of the mains power, disconnection of the standby battery or high impedance in the charging circuit
will cause the

control panel.

16.10 Disablements
It is possible to disable parts of the system. This may be required if there are works going on in a building
which may cause the fire alarm system to operate in error.
34B
16.10.1 Disable zones
To disable zones, the
Enable Control key should be inserted and the mode button pressed until “d” appears
in the first of the two seven segment LED displays. The
Select button should then be pressed to select the
number of the zone which is to be disabled in the second of the two seven segment displays. Once the
desired zone is displayed, the enter button should be pressed to confirm the disablement.
The
Disable LED will light and the Zone Fault LED will light for each disabled zone.
A disabled zone is shown on the seven segment display as ‘dx.’ (where x is the zone number from 1-8).
If the ‘x’ is flashing, it means that there are activated devices in that zone and re-enabling it will put the
control panel into the fire condition.
The panel should be Reset before enabling any zone with a flashing “dx.” Indication
