2/4/8 ZONE CONVENTIONAL FIRE ALARM CONTROL PANEL
| 11
DISABLEMENTS
Certain fi re alarm panel functions can be temporarily disabled (i.e. switched off ) to suit certain conditions. For example, if
there is a risk of a false alarm in a zone, e.g. from vehicle exhaust smoke in a loading bay, it is possible for the user to disable
that zone during the risk period and enable it again afterwards. Another example is the disablement of outputs during a rou-
tine test or temporary fault.
The following is a list of options that may be disabled by a level two user at the fi re alarm panel and the eff ect their disable-
ment will have on how the system works:
To disable or enable any of the above options:
1. Put the fi re alarm panel into access level two (see Authorised User Controls - page 6).
2. Start the selection process by pressing and holding the Next Option button for 3 seconds.
The General Disablement light will fl ash and the Fault light relating to the fi rst option in the above table will fl ash to show it is
selected.
If the light fl ashes at a slower rate than the General Disablement light, the option is enabled.
If the light fl ashes at the same rate as the General Disablement light, the option is disabled.
3. If necessary, press the Enable/Disable button to toggle the selected option between disabled and enabled.
4. To confi rm your choice, press the Next Option button.
This will move the selection process on to the next available option in the above table and the Fault light relating to this
new option will fl ash to show it is selected. The previous option’s Fault light will now be lit steady to confi rm it is disabled, or
switched off to confi rm it is enabled.
5. Repeat steps 3 & 4 for every available option until the selection process is complete.
The disablement/enablement process is complete when all available options have been selected in turn and the
Next Option button is pressed for the last time. At this point all disabled options will be lit steady and all enabled options will
have their lights switched off .
Note: The selection process can be exited at any time by pressing the Exit Access Mode button, or by turning the keyswitch to
‘O’ position. The only changes that will be saved will be those made prior to the last press of the Next Option button.
