Smoke Detectors
|
|
|
|
The OptoRex optical smoke detector is eminently suited to
early detection of smoldering fires, but it also quickly detects flaming
fires that produce smoke. The newly developed, high quality optoelectronic
system ensures a homogenous response behavior across a wide smoke spectrum,
ranging from light-colored to dark smoke.

Heat detectors

|
|
|
The ThermoRex heat detector works according to the
differential heat measuring principle. The temperature sensor consists of
two precision NTC thermistors. The absolute and
the relative change of ambient temperature are measured. The open
protective housing means that the ambient temperature has an almost
unhindered effect on the sensor and protects it against mechanical damage.

Combined
Smoke and Heat Detectors
|
|
|
|
The PolyRex combined smoke and heat detector works on the
principle of light scattering. The heart of the detector is a high-quality opto-electronic system enclosed in the measurement chamber
that screens off extraneous light but optimally detects light and dark
smoke particles. Parallel to this, the heat sensor takes over the function
of temperature monitoring. The signals of the increase in temperature and
optical smoke measurement are added together which leads to optimum
response and guarantees increased detection and fault reliability.

Linear Smoke Detectors
|
|
|
|
The
linear smoke detector is the ideal detector for monitoring large
store-rooms and production workshops or atrium type buildings. It consist of the actual detector and a reflector placed
opposite the detector. The detector contains a light transmitter and a
light receiver. The transmitter supplies a bunched infrared beam, which is
returned to the transmitter by the prism-shaped reflector. If smoke is
penetrating in the light beam, the receiver can convert the decrease of the
beam to an alarm signal.

Flame Detectors
|
|
|
|
The
infrared flame detectors are suitable for the detection of smokeless
combustible liquid and gas fires, as well as smoke & forming open fire
involving carbonaceous materials as contained in wood, plastics, gases, oil
products etc.

Duct Smoke Detectors
|
|
|
|
Reliable
monitoring of fresh air, used air and air re-circulation
ducts for
smoke in air conditioning and ventilation systems
The duct
smoke detector is a passive monitoring system without its own fan. It
utilizes the differences in pressure in the ventilation system in order to
carry continuous air samples via the air flow tube (bypass) from the
ventilation duct to the air duct sampling chamber.

High
Sensitivity Air Sampling Smoke Detectors
|
|
|
|
High
sensitivity air sampling smoke detectors can be used wherever high
sensitivity is required and where point type detectors are unsuitable due
to inaccessibility or room height, where they would spoil the décor or as protection
against tampering. The air is carried with an ventilator
to the detector unit via a pipe system with defined air sampling holes installed
in the protected area.
