THE MODEL BOOMERANG Scomply with and exceed the European product standard EN 54-12 and have obtained
certification from the most distinguished European testing institutions. The models are built to an IP 44 rating. Available
4 models: two for “smoke” (Boomerang S) and two for “fire and smoke (Boomerang SF):

THE BOOMERANG S MODEL (for Smoke detection only) consists of three units:
The TRX transmitter unit – the reflector RFX – and the interface
INT8BA. The interface unit is necessary for providing the control unit with electrical fault and open or closed contact fire information. The electronic optical device is housed in a single mechanical casing and emits two conical beams of infrared light at different angles. These cross the protected space and strike the reflection device. The infrared beams hit the reflection device with equal intensity and are bounced back across the protected area to precisely strike the optical receiver device. If any event involving smoke or fire takes place in the protected space and develops in ways and frequencies equivalent to those found in natural fires, and if the complex of ensuing events
progress over a determined period, the detector will emit an alarm signal. For an alarm to be given these symptoms must interfere with the infrared beams. This is possible even if the start of a fire occurs at a considerable distance (up to 7.5 metres each side) from the vertical of the infrared beam. The working system exploits the configuration of the natural roof type to cause the symptoms of an incipient fire to converge to where the fire detector is installed.
The Transmitter unit TRX has a practically instantaneous sensitivity checking system through special circuitry which makes any additional long term sensitivity checks quite unnecessary. LEDs can be seen through a transparent section of the front main filter window. These indicate:

“Green” Power supply on, “Red” Smoke alarm, “Red” Fire (model SF only), “Yellow” Operating fault

The system has an automatic exclusion system to deal with a situation where an object passes between the TRX and the reflector RFX units. When the obstacle is removed, reset is automatic and normal function recommences immediately.
The model can handle different smoke sensitivity levels over a very wide range so that the alarm thresholds can be selected as required for the context. Smoke sensitivity adjustment for the S model can be managed by the specific control instruments UTA or ADM.
The use of this detector in civil or industrial environments that may be subject to all kinds of disturbances, requires no special knowledge or skills of the operator, but strict adherence to the instructions contained in every individual packaging is required.


THE BOOMERANG S F MODEL (Fire and Smoke detection) also consists of three units:
the TRX - the reflector RFX – interface INT8BA. The working principle, size and quality of the devices are similar to those of the S model. This model's essential difference is that it processes smoke and/or fire data analysed by the Receiver unit. The processing of the data consists in translating each aspect of incipient smoke and fire identified by the receiver through electrical signals, each of which corresponding to calculations regarding a single "symptom" of a fire from smoke and/or from fire.
This examination of the data is not an abstract or theoretical event but is associated with the specific working conditions of the protected area in which the detector is installed, even though this may be an area subject to many disturbances of various kinds. This model's algorithm makes highly subtle and complex calculations possible that enable the detector to precisely identify data that reflect the presence of fire or smoke, on the basis of probabilities and proven scientific parameters. Calibration of the BOOMERANG SF involves the use of a portable UTA or ADM unit.
The use of the BOOMERANG SF detector in civil or industrial environments that may be subject to all kinds of disturbances, requires no special knowledge or skills of the operator, except for the ability to select a suitable distance between the units' installation and the top of the ceiling.
The UTA98 instrument connected to the TRX unit allows the operator to measure directly the intensity, morphology and duration of any disturbances present in the environment to be protected. With the ADM adapter, a similar reading can be taken of corresponding electrical values (mV), using a simple additional tester. An understanding of these values means that properly reasoned threshold settings for Fire and Smoke can be established according to the possibilities provided by the protected environment.

The size and shape are the same as for the BOOMERANG S and BOOMERANG SF models. The two models differ in the colouration of the housings’ anodising: For the BOOMERANG S, Black. For the BOOMERANG SF, Silver.

INTERFACE INT8BA 24 Volt DC
The interface unit is necessary if the control unit accepts closed or open
input contacts for faults and fires. It must be powered by 24V DC, the same
applying to BOOMERANG S and SF. Delivery configuration can be with or
without an IP 55 rated plastic housing.
