10 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.
