sounder/strobe problems

[williamalex1]

Hi Guys, I'm a 70 year old retired spark so please be gentle with me.

I finally renewed my old Sigma sounder box after a lightning strike a few years ago. I fitted a new Honeywell AG6 strobe/sounder connected to a Citadel Accenta 8sp400 mini G3 panel.

The system sets and works fine BUT every 5 minutes there's 2 high pitched beeps coming from the keypad.

Any thoughts guys

thanks in advance

Billym.

Are you sure its the keypad?

[williamalex1]

Yes defo  the key pad, the panel is in a cupboard in an upstair bedroom.

[james.wilson]

No I meant do you have a battery smoke CO2 etc detector close by?

[williamalex1]

Yes but it's a separate system, when i disconnect the  battery and mains supply to the panel and the beeps stopped .

[PeterJames]

Really? Are you sure the smoke is not on the same mains? It is not the sort of noise that the intruder panel makes.

What's bellbox do when you disconnect mains and battery, as a side topic 

[williamalex1]

The beeps are the same sound as when using the key pad.

[PeterJames]

Button sticking perhaps?

The sounder went off for about 15 minutes when the power was disconnected and now the battery in the box is flat.
