R24 & R12 – Auxiliary Relay Units

Auxiliary relay units provide two relay outputs to allow fire systems to switch field devices such as fire door retainers and smoke vents or to shutdown fans.

Indication of relay status is provided via an LED with a wide area of illumination and high on/off contrast. The standard version is a single gang unit with ‘Auxiliary Relay Operated’ text.

Blank and alternative text versions are available on request.
