Smoke Detector - (ReliaTel™ Only)
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.
Important: 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 smok e 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 below.
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. See the following field wiring
example below.
