Gardtec 840 removing smoke alarms from panel and program

[Reddwarf4ever]

 

Hi

i want to remove the 8 smoke alarms I have wire to the system, they are long out of date and want to replace them with standalone smoke alarms.

 

i will need to disconnect them from the alarm panel and most likely from the program via the keypad.

 

i have the engineer code, wonder if it’s obvious where the smoke alarm connections would be as a starting point.

 

thanks

PS the alarm manual says the smoke detectors at zones 12-16 inclusive

Make zones spare or unused

Sorry that answer didn’t really address my concerns

 

Hi

 

i have the engineer,installation & user manuals, so will be able to remove the required zones, although if anyone knows the exact steps to remove zones would save me trawling through the manuals.

 

as I need to physically remove the smoke alarms from the ceiling , to replace with standalone smoke alarms, I need to isolate or terminate the power supplies to each.

 

unless I can easily determine where on the panel the power supplies are taken from, I plan to remove each alarm in turn and terminate the cabling with a connecting block or tape them up and push the cable into the ceiling space through the existing hole. Once done, I can then remove them from the programming.

 

i am not just being a cheapskate, but am a pensioner on a very low budget and certainly can’t afford £200 Hr which the installer company want to charge me, worse still they can’t give me any idea of the time it will take......bit like a blank cheque .

 

so hopefully someone can read what I need to do and advise me.

 

thank you in advance

Removing Zones
(Master & Main codes only)
If programmed by the installation company individual zones may be removed, this may only be done by a Master or Main level of code. It should be noted that if an Area Main code is being used, only zones associated with that area may be removed.
1) With the display showing:-
2) Enter a Master or Main level code, the display will show:-
(User Names on 816 & 840 Only)
3) Press NO, the display will show:-
4) Press YES, the display will show:-
5) Enter the zone number you wish to remove followed by YES (pressing
NO will 'un-remove' a zone), the display will show:-
6) Repeat step 5 until you have removed all the required zones.
7) Press 0 to escape, the display will show:-
8) Press YES, the continuous exit tone will sound.
9) Exit the premises via the authorised
exit route ( the exit tone will change as detectors are violated). When the premises are secure
listen that the exit tone returns to the continuous tone. Wait until the exit tone finishes before leaving.

Note: Zone remove is only effective for the one set.

so the procedure seems straightforward enough, bit what does the line above mean ? Does it mean this is only temporary ?

Yes that's a zone omit as a user function. You need to remove the zone in programming.

Why remove them if they work? Surely it would be more sensible to replace them if you need.

Alarm company are unlikely to be impressed if you remove stuff, you also risk the possibly of having no alarm at all if you can't remove them correctly.

RE call out would be 1-2 hours work I imagine.

Removing the existing smokes from the alarm in favour of stand-alone, battery operated detectors is a backwards step.

The existing detection is designed to warn not only the occupants of the house that there's a fire but also neighbours etc via the external sounder, so hopefully they can call the fire brigade. I'd imagine a system that size would be monitored by an ARC as well, so yet another way of calling the brigade whether your home or away.

Stand-alone detectors will inform you of a fire if your there but if a fire breaks out when your not there, no one will know.

If the system is under a maintenance contract, you'll no doubt invalidate that by tampering with the system.

Yes it does lol

 

Make zones unused or spare , then flaff around with it and hop you don't blow a fuse or something

 

On a side note put linked smokes and you can still link it to the alarm 

 

Doing above means you can remove all of them leave cables as is , protect all the ends incase you have them put back 

 

And then fit whatever junk you want

Bugger me I'm getting old

 

When I first discovered t'interwebs a username containing 'red dwarf' usually denoted a spotty 15 year old herbert

 

now its the mark of a penniless pensioner

 

but seriously, no really, I agree - replacing with battery devices is a backwards step.

 

Even nest ones as they are designed to be binned in ten years, they simply refuse to work past their tenth anniversary.

 

If you think you have the skills to reprog the unit, which you may have, or not, who knows, whats stopping you replacing the smokes?

 

You'll actually find 12v smoke detectors CHEAPER than decent quality mains+battery Aicos for a start, and the wiring and panel area already in place, so...
