Application
The Halon Bank BeamMaster-H Smoke Detector is designed for detection of
smoke in large spaces such as halls, warehouses, museums, theatres etc.,
where point detection is impractical or more costly. The unit detects
smoke linearly over the protected range enabling early detection before
the fire spreads.
Operation
The emitter projects a near Infra-red beam which is detected by the
receiver. The beam is pulsed to reduce the overall current consumption and
improve the noise rejection characteristics. Powered directly from the
Zonemaster conventional zone without the need for an external supply, when
the zone is reset, the detector is automatically reset.
The emitter and receiver are synchronised via a direct 2 wire link which
also supplies power to the emitter. All other field wiring is connected to
the interface on the receiver. If smoke obscures the beam the receiver
detects this and indicates a fire. Any gradual reduction in received light
through environmental contamination is automatically compensated for
within the detector.
In normal operation two status LEDs indicate a fire or fault condition,
these are viewed through a unique lens that allows good visibility from
any viewing angle particularly from beneath the unit. An output is also
provided from the receiver for a remote fire indication.
The unit indicates a fault on the zone under the following conditions:
Compensation
limit exceeded
Total
Obscuration of Beam (Under this condition a fire signal will also be
generated following a pre-defined time delay.)
Receiver
cover left open
Receiver
unit removed from zone
The
BeamMaster-H can easily be connected to Halon Bank Controlmaster analogue
systems by use of the Fireseeker Zone Interfaces. This enables the
BeamMaster-H to be loop powered and reset from the loop when the user
operates system reset from the fire control panel.

Conventional Fire Detectors
The Fireseeker ZA range of conventional fire detectors are compatible with
Halon Bank Zonemaster fire control panels. Each detector has been designed to
provide an aesthetically pleasing modern
