Firebeam Reflective Optical Beam Smoke Detector with Controller and Reflector (5 – 70m)
High level beam detection has always been a cost effective way to offer detection over large open areas; however, owing to building movement and high level access requirements for maintenance purposes; it has proved unreliable and expensive to service. The Fire Beam has been specifically designed to overcome these problems using advanced technology; enabling optical beam detection to be used with complete confidence.
So what is this advanced technology?
The Fire Beam will self-align itself to the center of the reflector whilst commissioning and will automatically keep its alignment when building movement occurs. This advanced intelligent motorization results in saving time, resources, reputations and ultimately money. The Fire Beam comes complete with a low level controller, ensuring all service and maintenance functionality is easily accessible.
- Very Low Power: using only 3.5mA any state opens up a whole world of options. In some cases you can loop power the beam, for instance using an Apollo xp95 mini switch monitor allows you do just that and turns the conventional Fire Beam into an addressable unit.
- IP65: means no ingress whatsoever making The Fire Beam ideal for environments, such as food processing halls, as it can be hosed down. IP65 also means nasty little creatures can’t set up home inside and jeopardize the effectiveness of the detector.
- Easy Clean Lenses: The Fire Beam has been designed to be easily cleaned due to its flat surfaces. Unlike other beams all the moving optics are safely encased inside the waterproof enclosure so you won’t accidentally knock the beam out of alignment. This means The Fire Beam can easily be cleaned from ground level using something like a no-climb pole and suitable attachment.
- Hysteresis: Changing the hysteresis will change the delay in returning from a fire state back to a normal state. For example, the beam is factory set at 15% so if the beam falls into fire at 65% (35% threshold) it has to recover 15% to 80% before it returns to normal. This action prevents small fluctuations in returned signal causing the beam to fall in and out of a fire state. This can be adjusted to anywhere between 1% and 40%. The hysteresis can simply be adjusted from this new menu option.
- Beam Phasing: It is possible that beams that face each other will cause problems as their sample rates could coincide and result in unreliable readings, meaning false auto-alignment and unreliably in service. With the introduction of phasing it is now possible to mount beams facing each other with reflectors in-between. There are up to 7 different sampling rates to choose from, alleviating any cross talk problems.
- Auto-Align Time Delay: Again this facility is useful in environments that are liable to occasional short term obscuration. Pre-set at 4 hours this can be altered to anywhere between 0 to 12 hours if required, to allow the environment to clear.
