Supply/exhaust air set - Opening detector for intrusion detection ZAS K2

Supply/exhaust air set - Opening detector for intrusion detection ZAS K2 – Schalk – ZASK29 – 4046929401081: Supply/exhaust air set ZAS K2 Mounting type surface-mounted/recessed, color white, The ZAS K2 is a complete device set, consisting of the active isolating relay ATR U2 and the magnetic contact MKW 1. Ideally suited for controlling exhaust air systems/extractor hoods in connection with room air-dependent fireplaces in accordance with the Firing Ordinance . The active isolating relay enables mains voltage consumers to be switched in the simplest possible way using extra-low voltage contacts. There is no need for a power pack to control the relay coil, since the relay generates the necessary control voltage (24 V DC PELV) internally. In conjunction with the magnetic contact MKW 1, for example, supply air monitoring, which is often required for closed rooms, can be implemented with little effort when operating extractor fans. The changeover contact makes the ATR U2 extremely versatile, ATR U2: 230V AC, 1 changeover contact 10 A
