Product Overview

The Siemens intelligent manual fire-alarm boxes (Models HMS-S | HMS-SZ and HMS-D | HMS-DZ) provide the most advanced method of address programming and supervision

Each Model HMS-series manual box achieves the state of an ‘intelligent-initiating device’ by incorporating custom microcomputer-chip technology with sophisticated, bi-directional communication capabilities with the panel, which include Siemens Modular, as well as Siemens 50-point, 252-point and 504-point addressable FACPs.

The Model HMS- series manual fire-alarm boxes are also included in US Coast Guard (USCG) approval for use in marine and other harsh environments, when used with the Siemens 252-point and 504-point USCG approved addressable system

Specifications

Models HMS-S | HMS-SZ and HMS-D | HMS-DZ are constructed of durable, molded polycarbonate material that is matte finished in red with raised white lettering. The housing accommodates a ‘pull-down’ lever, which ─ when operated ─ locks into position; indicating the firealarm box has been activated.

The pull-down lever remains down / in the ‘locked’ position, until the fire-alarm box is manually reset. The manual fire alarm box can only be reset by opening the hinged housing cover with an Allen key; followed by closing and locking the cover. Models HMS-S | -SZ and HMS-D | -DZ operate with Siemens ─ Fire Safety FACPs. The microcomputer chip to the manual fire-alarm box has the capacity of storing ─ in memory ─ identification and important operating-status data

Models HMS-S | -SZ and HMS-D | -DZ are fitted with screw terminals for connection to an addressable circuit, and can be either surface or semi-flush mounted.

The Model HMS-series manual fire-alarm boxes derive their power, communicate information and receive commands over a single pair of wires. Each box is compatible on the same circuit with all Model `H’-series detectors, interfaces or addressable, conventional zone modules.

Device / Programmer Tester – Model DPU

Innovative technology from Siemens ─ Fire Safety also allows all Model HMS-series intelligent manual fire-alarm boxes to be programmed via the Device Programmer / Test Unit (Model DPU). The programmer / tester is a compact, portable and menudriven accessory that makes programming and testing of a manual fire-alarm box device faster, easier and more dependable than previous methods.

Model DPU eliminates the need for mechanical-addressing mechanisms of a device because Model DPU electronically sets the address of the manual fire-alarm box into its microcomputer chip, non-volatile memory. Therefore, vibration, corrosion and other conditions -- which can compromise the functionality of mechanical-addressing mechanisms – are no longer an issue.
