[Ticket Question] Which fire sensor for the Sterling 10?

[securitywarehouse]

i need to replace 3 fire sensors at home that are compatible to my house alarm system. it is a sterling 10 by pyronix. i am told they have to be normally closed. can you recommend a sensor

Fire sensors are 24v, so you will need to look for a 12 volt sensor to find one compatible with an intruder alarm system
