Hi,

I bought an Optima Compact Gen4 over two months ago. Since then I have been trying to connect it to a bell box from another manufacturer without success. Honeywell technical support simply say that I MUST buy their Reson8 siren!

The bell box model is Mars 2000, the instructions and circuitry are attached. I have tried numerous combinations of the panel's A/D/B terminals to the bell's H-/H+/SO terminals but the bell is never triggered by the panel. I know that the bell works because I can manually trigger it by changing the voltage on H+ or H-.

Any tips before I give in and buy the Reson8?

Thanks...

13.8+  = D

13.8-  = A

H- = no connection

H+ = B

SO = Strobe -

LB = No Connection

T = T

 

 

You may need a relay for this sounder to be compatible for this panel

Basically this sounder is an old style SCB

 

You may need a pull up resistor.

If that configuration doesnt work then connect a 1K resistor between B on the panel and D

 

Alternativly you will need a relay to clean switch the voltage req.
