BOOMERANG LINE
Optical beam smoke and fire detector
The Boomerang Line of detectors is made up of modulated optical line detectors as defined by the European standard EN 54/12. The detector is made up of a Transmitter and Receiver unit in a single housing. This device is associated with a control unit and a power supply unit.
The detector works by the ’Transmitter unit emitting two infrared beams that cross the environment under surveillance to hit the “Reflex” reflection unit. The reflection unit, consisting of a prism in a special housing or a Retroreflector, depending on the model, reflects the IR signal received back across the room to the receiver unit. The receiver unit demodulates from the signal received the presence of any smoke and/or fire that may be present in the environment when it cuts the radiation emitted by the Transmitter unit.
As regards the distance covered by the Boomerang model, there are two main models: the 5P70 and the 6P150, where the number indicates the distance covered.
This model must be calibrated and checked with UTA and ADM instruments, too.
BS70 - BSF70 (10 ÷ 70 m)
BS150 - BSF150 (71 ÷ 150 m)
Certifications
As with the ARDEA model, depending on the ability to detect primarily smoke or fire the models can be further divided into the following:
| BOOMERANG SF (SF=smoke/fire) |
|---|
| In addition to the detection of ‘smoke’, this detector also provides for the detection of ‘fire’ if it is associated with spontaneous combustion in nature. |
| BOOMERANG S (S = smoke) |
| This detector provides for the detection of fire phenomena mostly related to the prevalent presence of smoke. |
Models
Both models, in the four version, require an interface (INT8C) for their connection with the control and indicating equipments.
BS70 - BSF70 (10 ÷ 70 m)
BS150 - BSF150 (71 ÷ 150 m)
| BS70 / BSF70 |
|---|
The reflection system detector is suitable for spaces where the requirement of system simplicity dictates that power cables do not have to be run to two different points: i.e. the Transmitter unit and the Receiver unit ( TX and Rx units). Power can be provided only to one point (the TRX) with this system, since the opposite reflecting unit is passive (the Retroreflector). In addition to the above features for the SF model, there is the possibility of detecting of beginnings of a fire using the same technology used by Ardea SF. |
| BS150 / BSF150 |
This is the only reflection system detector with an operating distance that is practically the same as that of Transmitter – Receiver system. What is special about the S-SF model is that its reflecting body is a prism that permits calibration even under the worst operational conditions, while assuring constant detection even with misalignment up to as much as two degrees. Other advantages of the SF model include being able to detect the beginnings of a fire using the same technology as that employed by the Ardea SF. |
