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 fire-alarm 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.
