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

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.
– If you have more than 5 HVAC units, you can connect all the supplies together on one power
supply (up to 10 HVAC units), and all the returns together (up to 10 HVAC units) on another
power supply.
