daiashthomas Posted June 11, 2008 Share Posted June 11, 2008 new extension to house and need hard wired fire detection with battery backup could i get away with fitting smokes in my house on the intruder alarm as it gives different sounds for fire and alarm? as they are technically mains powered with battery back up, instead of the mains powered ones whitch are more expensive plus i want to link them to the intruder alarm anyway for signaling purposes. thanks Trade Member Link to comment Share on other sites More sharing options...

james.wilson Posted June 11, 2008 Share Posted June 11, 2008 agreed, they may not like it, but until they enforce bafe then it wont stop. As mainly intruder id take the oposite view. While an intruder alaerm can never offer what is required from a full 5839 fire alarm, assuming you have enough local sounder (ie local to each detector) then id say that smokes linked to an intruder alarm are better than interlinked. I say this with no real expereice of interlinked etc, and have 4 x menvier m12 4 in 1 smoke detector 's in my own house.

arfur mo Posted June 12, 2008 Share Posted June 12, 2008 as for fire regs - could not possibly comment, but right of the bat i would not connect any smoke detector to any intruder alarm system, i've posted in the past i would ban the practice, but i respect other companies do this and nothing illigal about it.. imo the problems are many, the very 1st concern being distinguishing between a faulty intruder and real fire alerts, simply as the audible signalling being from the same sounder devices which are not fire rated or placed as often as a true fire alarm so the minimum noise is reached in all parts. might be fine if you or your familie might know the difference before you home fills up with smoke, but what about a guest or a neighbours child? even a neighbour? if you intruder side suffers a series of false alarms the 'respect' level falls which could be a tragedy. by mixing a vital to life and a vital to contents system you risk a fault on one impacting on the other making boith systems inactive, not good idea surely? ideally you would wire the system as a proper full on fire alarm, if thats not viable and you must have a 'diy' style fire alarm (and i'd need some convincing you would) then use a separate intruder panel and 12 volts smoke detectors specifically designed for the connection to intruder panels and separate sounders/strobes clearly marked. otherwise as i see it you might as well get some simple cheap battery detectors and spray them about for what extra good it will be but thats just my opinion . regs alan If you think education is difficult, try being stupid!!!!

Chorlton Posted June 12, 2008 Share Posted June 12, 2008 As it's your own house I see no real problem with it so long as the battery back up and positioning complies with Document B. The battery back up of the panel will be 8hrs where as the internal battery on a mains powered smoke will be many days. However the upside like you say will be the monitoring Chris.

james.wilson Posted June 12, 2008 Share Posted June 12, 2008 Arf, he is talking about interlinked smoke sensors with built in sounders.... connected via normal mains cable not a full fire alarm. I agree that int fire shouldnt be used in the place of a full fire if that is needed, but most people have 9v smoke alarms and intruder connected are amuch better idea. I dont have a 5839 system in my own house with red fp coming down the wall in my hall to a huge panel for example.

I know that in commercials the brigade only turn out the once to smokes that are not part of a 5839 system. Under part 6 you can of course use an intruder system depending on the size of the house.If it's big enough you have to have a 5839 Part 1 system (including MCP's!).

daiashthomas Posted June 12, 2008 Author Share Posted June 12, 2008 the only signaling will be to me via speech and text dialer. (and then the Mrs if i don't acknowledge the message) and it's my own house and only require 2 smokes, plus i would probably use a sound bomb for the fire and just the speaker for the intruder, although you can have different sounds from the speakers. and as far as batteries go I'll be fitting at least a 17ah to intruder panel. and also as far as disturbing my neighbors goes they are 25 - 30m away on one side and over 40m on the other side of me.
