Circuit Wiring for ULC-Listed Installations
Use Form C contacts and 4,300-ohm (yellow-orange-red) resistors to provide an alternate
supervised connection for ULC-listed central/monitoring station installations.
To series-connect two Form C devices, one with a detector cover tamper and one without, install
the 4K3-ohm resistors in the first and second devices as follows:
