Smoke Detector Customer Low Voltage Wiring

When interlocking System Sensor smoke detectors together, all of the detectors must be powered from the same power supply. If multiple smoke detectors are required, all detectors must be disconnected from the HVAC unit power supply and connected together from another single source supply.

Note: Do not interconnect smoke detectors together that have separate power supplies. Do not exceed ten smoke detectors on one power supply.

Note: Multiple System Sensor smoke detectors are connected together using terminals 1 and 12 on each detector.

If you have supply and return smoke detectors in all HVAC units, you can connect a maximum of 5 HVAC units (10 detectors) up to one power supply. See the following field wiring example.

If you have more than 5 HVAC units, you can connect all the supply detectors together on one power supply (up to 10 HVAC units), and all the return detectors together (up to 10 HVAC units) on another power supply. See the following field wiring example.
