Plus One Relay Expansion Module - Aerosphere ONE Add-on

The Aerosphere Plus One Module expands the capabilities of the Aerosphere One (BML-25), enabling direct control of gas shutoff valves and integration with external systems. Designed for flexible installations, it allows operators to connect multiple horn strobes, interface with a fire panel, gas valve, other external devices. With the built-in relay, two independent outputs, and remote mounting capability, the Plus One Module simplifies wiring while supporting more advanced system configurations. It is ideal for locations that require added control, improved system communication, and a more streamlined approach to CO2 compliance. Important: To trigger ventilation systems when critical CO2 levels are reached, an HVAC Control Box is required. Part #: 12238
