No it doesnt look like it, whoever installed it linked out the tamper

does anyone have a comment relating to the black wire from the bell box ?

 

 

If you had picture taken in the same postcode or with something the grainy tat from mobile of the same vintage as the sounder (1990's)

 

I'd guess at in being the remain of the fly lead for tamper switch ?

Is it redundant or does it need to be terminated ?

 

 

Its all redundant, just buy a new external sounder the one you have is tat once sold in wickes...

Hi Peter,

 

Thank you for your assistance. The bell box has an active tamper - as I removed the lid the siren went off - the tamper was a little spring loaded stick attached internally to the blue plastic in the picture. That being the case, does the loose black need go into one of the terminals please and if so which one ? Many thanks, Paul  

No it doesn't need any more wires adding the sounder should self activate when you take the lid off

Wires dont remove themselves, I cant think why you would think they do ?

I'd suggest you power it all down then find out it's a battery operated bit of junk, nest smoke, other smoke detector then I'd look for alarm clocks birthday cards etc. A powered down alarm is just that. 

We get so many of these and always the op is convinced that its the alarm, I remember as an engineer telling a customer over the phone it was a low battery on their smoke, they insisted I come out. £70.00 plus VAT (it was the early 90's)  callout later, I found an old smoke detector in a kitchen drawer with the battery still in it.

 

Its like we tell them what it is and the dont believe us   

Had exactly the same thing many times.

 

Once a customer was convinced it’s was the alarm and insisted we attend site to fix. I advised that we would charge for the visit.

 

On arrival I found an old carbon monoxide detector down the back of a sideboard in the lounge, I was on site less than a minute.

 

they kicked off big time when they got the bill and canceled there contract, they did pay though.

 

good riddance nob heads.

Remember a few years ago, customer called us out because their alarms bleeping. Was someone’s hair straighteners, which were left switched on!!

Don't be so dismissive - my Mother's alarm is doing the exact same thing. I too disconnected the power and the battery and the chirping still continues. Maybe it's the caps discharging but this is ridiculous. It is NOT a smoke alarm - give the guy SOME credit.
