Hi, I wonder if anyone can help me?

I have a Guardtec 500 Control Panel and am struggling slightly with wiring in the external bell.

The control panel has the following terminals:

12v +

12v -

Strobe +

Strobe -

Bell +

Bell -

Bell Hold -

SAB Tamp

I currently have it wired in as follows:

Panel Bell

12v + 12v +

12v - 12v -

Strobe + Strobe +

Strobe - Strobe -

Bell + Trig +

Bell - Trig -

When an alarm occures, the strobe flashes but theres no siren. Have I got the wiring wrong?

Please help?

yes - disconnect the bell+ triggers, they are cancelling the bell - triggers

which bell? list the terminals.

You don't seem to have tamper connected.

Use this,

panel bell

Bell + ---------------- + (12v supply)

Bell - ---------------- trigger -

Bell hold - ----------- -(Ov supply)

Sab tamp -------------- Tamper return

Strobe - -------------- Strobe Ov

Thanks for this advice.

I started by trying the first option of disconnecting Bell + which worked perfectly.

I'll keep the third response in mind should I ever remove the bell in the future.
