Description

The Siemens HZM is an intelligent device that connects a single zone of conventional devices to an analog loop. Also, the Siemens HZM can power up to 15 two-wire ionization and photoelectric smoke detectors (Siemens Models ‘3’ or ‘11’-series). Model HZM | – Z can power one (1) beam detector (Model PBA-1191) with no additional devices, and can also monitor listed alarm-causing shorting devices, such as water-flow switches, thermal detectors, manual stations, etc.

Each Siemens HZM can be assigned a 32-character, custom alphanumeric message. The multicolor LED ─ visible through the cover plate ─ indicates the condition of the circuit. Also, the multicolor LED displays red for Alarm events, yellow for Trouble commands, and green for normal operation.

In general, Siemens HZM, which does not require any mechanical address programming, supports ‘Class A’ (Style D) or ‘Class B’ (Style B) wiring, as well as occupies one (1) address on the Model DLC circuit. Besides, model HZM is programmed and tested using the Siemens ─ Fire Safety Device Program / Test Unit (Model DPU).

Additionally, Model HZM has interconnectivity with Siemens Modular panels and FireFinder® XLS, as well as with the Siemens 50-point, 252-point, and 504-point addressable systems. Use of Model HZM | -Z modules allows a fire system to use a combination of intelligent as well as conventional devices for use with a substantial reduction in the wire.
