Sense alarm Fire alarm

[cliffed]

In the CFP alarm sense manual, the circuit showing the alarm sense sounders shows + - at the sounders.
I just took this to indicate the sounders were polarity conscious, although it doesn't actually say this. Says to look at the manuals for each device.

Just looked on the C-tec website, your right they're not polarity conscious. In answer to your earlier question, it looks like all 5500 series sounders are compatible.

Thanks

How many zones are you using ?

2 zones

 

[cliffed]

Have you dissed the circuit and checked the resistance?

Not checked the Eol resistance yet,the engineer didn't look at that

2 zones

Are both showing faulty or just 1 ?

Just read your post in reply to Lee, you mention End of line resistance ?
The manual I've got, shows 0.47uf 50v End of line Capacitors on the sense circuits.
The 6k8 resistors are for when you install conventional sounder circuits.

Wonder how this turned out in the end ?

Wonder how this turned out in the end ?

end of line or end of saga?

Possibly a mix up with the capacitors & resistors, we may never know.

Cheers,on hols at moment,will update when home,they are resistors on circuits for Eol

Are you using Apollo Alarm Sense or are you using a 2 wire system.
If your using a 2 wire system then the sounders must be wired reverse polarity. All fire alarms weather on sounder circuits or combined zone circuit, change polarity when in alarm status, this is why bells etc have blocking diodes. Can you state the panel and exact equipment your using

do they have to be wired in reverse? I was reading this link which said they are operated on voltage.

This is what we need to know....is it alarm sense or 2 wire, once with have the make of panel etc we sort

That's the info I read as well Lee, think the op said 2 wire.

having probs with Fire alarm.Its a sense alarm 2 wire,mcp's,detectors & sounders.
Goes into Fire mode,even when only 3 points are on circuit.
Are all their sounders compatible with the system,it's difficult to understand properly ,we have sounders,which are alarm sense,not the sounder & base ones,on their diagram.
Commissioning guy,going round in circles.

From the first quote its states sense alarm 2 wire systems, this could be Fire Sense, 2 wire system...it could be Apollo Alarmsense, Could be Haes 2 wire....so once we get all the info we can go from there

Yes it's a alarm sense system,a Haes panel,& appollo sounders

Back off hols on Sundsy,then to work,hopefully someone else sorted it ha ha.

 

[cliffed]

Wondering that too

Sorry about the waiting,all ok now,it was a loose smoke detector,not fitting to base properly.
Always the same the worst one to get at,needed scaffold to reach it.
Thanks for all your help.
