External Bellbox

[Mike35]

I have available a used Chubb external sounder with strobe. I do not have the original part number of the unit. The box has connections: SRN-, RTN-, SUPPLY-, SUPPLY+, STB-

Can you please advise if this box can be used as primary sounder with Comfort & relevant connections to Comfort

Almost all sirens should  be possible to connect to Comfort. The siren connections to Comfort are shown in http://www.comfortforums.com/forum16/2288.html

SUPPLY + and SUPPLY- should be the same as 12V and 0V on the diagram
STB- is the same as STR- (Strobe)

I suspect RTN- is the same as TRIG-

Other pins do not need to be connected
The bellbox does not seem to have a Tamper output which seems strange
You will have to try it out

Thank you for your response. As you have advised that there is not a tamper output, I will source a new box whilst I have easy access to the box location with scaffolding at high level to the front of the house.
