Relay Module
(optional)
The AirAlert TM 96d-RM8 relay module acts as an output
to the AirAlert TM 96d controller. The relay module
provides eight programmable relays for the activation
of ventilation and audible/visual alarm output devices
at programmable alarm levels. Since the relay module
is an output to the controller, it can be located at any
point within the gas detection network.
AirAlert TM 96d-RM8 Features:
• Fully compatible with the AirAlert TM 96d controller
• Equipped with 8 programmable DPDT relays
• RS-485 daisy chain installation
• LED visual indication status of each relay
