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

The D+H RZN 4503-T Set is a complete smoke and heat exhaust ventilation (RWA) set for the rapid installation of a smoke and heat exhaust ventilation system. It consists of the RWA push-button control unit RZN 4503-T, an RT 45 RWA push-button, the SD-O 371 smoke detector and a Type 8 battery for the integrated 72-hour emergency power supply. All components are perfectly matched to one another and enable quick and safe installation.

The RWA push-button control unit features an integrated RWA main control panel and a ventilation push-button within a robust aluminium housing. With an output of 24 V DC / 3 A, a detector loop and a drive unit, the set is ideally suited for smaller smoke and heat extraction systems in public, commercial and industrial buildings.

The control unit provides a stabilised output voltage and offers numerous safety and convenience features. These include circuit monitoring for short circuits and open circuits, remote reset of smoke detectors, RWA delayed activation, and connection options for visual and audible alarm devices. An optional wind or rain sensor can be connected directly. In addition, two freely programmable potential-free signal contacts and a slot for an optional add-on module are available.

The D+H RZN 4503-T is certified in accordance with ISO 21927-9, DIN EN 12101-10, VdS 2581, VdS 2593, VdS 2344 and the building regulations requirements of DIN 18232-9.
