Deactivating Optima XL4 house alarm

[telectrix]

you can release the circuit board from the housing without dissing anything so you can get to the screw behind.

lets do it steps....
1. removed bell box cover, disconnect battery or battery link, siren will not sound as system is not armed (only internal panel will sound)
2. removed mains & battery power at control panel.....Job done,

Hello again

This sounds suspiciously straightforward and peaceful - I was expecting the bell box (this is the 'external housing'?) to start sounding even if the alarm was not armed on the panel inside. So I could change my first steps to the following and you would expect it to be OK:

1. Remove cover from external bell box - at this point the external siren should not start sounding, because alarm is not armed on control panel inside.
2. Disconnect battery inside external sounder - the external siren will still not start sounding.
3. Remove front from control panel and reset alarm with keypad - internal alarm now silent.
4. Disconnect battery - neither external or internal alarms will start sounding.
5. Remove fuse for control panel circuit to disconnect from mains - neither external or internal alarms will start sounding


Thanks if you can confirm I am not getting the wrong end of the stick here.

Cheers

Totally correct (99% sure the siren wont sound, being basic alarm will not be programmed for 24hr bell alarm, nor would a scb be fitted) the other 1% at worse, the siren is scb and would only sound until bell box battery is disconnected, matter of seconds.

Hello all

I'm going to repost the list of steps here, just to make it easier in case if anybody else comes looking for this thread. But if anybody can spot a mistake or improvement that would be very useful.

The full procedure at the moment is:

1. Remove cover from external bell box - at this point the external siren should not start sounding, because alarm is not armed on control panel inside.
2. Disconnect battery inside external sounder - the external siren will still not start sounding.
3. Remove front from control panel: panel tamper spring will release, so internal alarm will sound, so reset alarm with keypad - internal alarm is now silent.
4. Disconnect battery - neither external or internal alarms will start sounding.
5. Remove fuse for control panel circuit to disconnect from mains - neither external or internal alarms will start sounding.
6. Unclip circuit board, so it can pushed out of the way to reveal all wall screws.
7. Unscrew control panel from wall.
8. Replace circuit board.
9. Reconnect battery.
10. Replace front to control panel.
11. Replace fuse for control panel circuit.
12. Reset alarm on keypad if necessary.

Thanks very much for all the suggestions.

Hello all

I am pleased to report that the procedure was successful, with no unexpected siren alarms or deafenings (repeated here in full for the sake of completeness):

1. Remove cover from external bell box - at this point the external siren should not start sounding, because alarm is not armed on control panel inside.
2. Disconnect battery inside external sounder - the external siren will still not start sounding.
3. Remove front from control panel: panel tamper spring will release and internal alarm will sound, so reset alarm with keypad - internal alarm is now silent.
4. Disconnect battery inside control panel - neither external or internal alarms will start sounding.
5. Remove fuse for control panel circuit to disconnect from mains - neither external or internal alarms will start sounding.
6. Unclip circuit board, so it can pushed out of the way to reveal all wall screws.
7. Unscrew control panel from wall.
8. Replace circuit board.
9. Reconnect battery inside control panel.
10. Replace front to control panel.
11. Replace fuse for control panel circuit.
12. Reset alarm on keypad if necessary.
13. Reconnect battery inside external bell box.
14. Replace external bell box cover.

Actually I didn't reconnect the battery inside the external bell box yet (#13), because I still need to mess around moving a couple of sensors inside the house, but I'm assuming this doesn't do any harm to the external sounder, just disables it?

Many thanks to all those useful suggestions above.

Cheers
