D+H RZN 4503-T RWA push-button control unit 3 A orange

The D+H RZN 4503-T is a compact smoke and heat extraction push-button control unit with an integrated main control panel and ventilation push-buttons in a robust aluminium housing. With an output of 24 V DC / 3 A, one detector line and one actuator group, it is ideal for compact smoke and heat extraction systems where control unit and operating panel are combined in one device.

The unit provides a stabilised output voltage and an integrated emergency power supply for at least 72 hours (battery sold separately). Up to 8 smoke and heat extraction control panels and 14 approved fire detectors can be connected. Temperature-controlled battery charging, circuit monitoring, remote smoke detector reset and night-time smoke extraction functions ensure reliable operation.

An optional add-on module enables comfort ventilation with adjustable opening width and ventilation time. Wind or rain sensors, visual and audible alarm devices, and two freely programmable potential-free signal contacts can also be connected.
