E-16D: How to Connect Multiple Smoke Detectors to a Single ENVIROMUX Unit Using the Digital I/O Expander.

Connect the E-DI16DO16 Digital Input/Open Collector Output Expander to the ENVIROMUX unit's RJ45 sensor port using up to 500 feet of CAT5/5e/6 cable. Up to 16 additional smoke detectors can be added to each connected expander. Since the E-DI16DO16 does not supply power, the E-SDS-CEPA Smoke Detector Sensor (CE) with an included power supply should be connected to the expander using 22-gauge 2-wire sensor cables. The power supply cable comes stripped and tinned; follow wiring configuration in the E-SDS-CEPA user manual for set-up instructions. Based on the desired number of smoke detectors, more expanders can be connected to the ENVIROMUX unit as long as there are RJ45 sensor ports available.

Other self-powered sensors, such as the E-IMD-P or E-CMD-P, will also work with this set-up.

Note: Since the ENVIROMUX unit does not provide power to the smoke detector, it cannot remotely reset the smoke detector power. Unlatch the activated smoke detector by simply unplugging and replugging the power supply.
