The Fire Beam is a reflective optical beam smoke detector with a motorised head that can align itself when commissioning, and continually correct itself against building movement. The device can be controlled and adjusted from ground level.
The nagging problems of alignment, power, and accessibility have all been addressed, providing a beam detector that is reliable and easy to maintain, and more importantly that will reduce the risk of expensive false alarms.
The Fire Beam protection system includes a motorised head unit containing an infra-red transmitter and receiver, a ground level controller and prism reflector.
Making use of the prism reflector the returned infrared beam is analysed for smoke contamination and registers a fire condition at a pre determined level. At ground level the controller unit is used to make operational adjustments. The standard Protection system covers a range of 5 to 40 meters, 2 further range kits are available, a 40 to 80 meter kit that utilises 4 reflectors and finally an 80 to 100 meter kit that makes use of 9 reflectors.
What makes The Fire Beam head unit so special?
The Fire Beam incorporates microprocessor controlled motors that intelligently align the head at all times. When first commissioning the head accurately aligns itself, and in operation the head will re-align should there be building movement, a problem with new build settlement and environmental change. The Fire Beam's unique ability to self align means that high level re-adjustment because of this is no longer required; saving time, disruption and importantly cost. The motorised head means greater reliability that will reduce troublesome false alarms.
Very low power
The Fire Beam protection system uses only 3mA at all times, so in most cases can happily be zone powered. Compatible with most major fire panels, the simplicity of the system usually means no extra power supply, meaning easier installation and a lower installation cost.
Designed to meet latest approvals
The Fire Beam has been designed from scratch to fully comply with EN 54 part 12. and exceeds European standards, in particular BS5839 part 1.
Technician friendly design
The Fire Beam has been built with the technician very much in mind. It has a simple wall mounting method for both the beam head and low level controller. Large, accessible, easy to use colour coded terminals make connection easy in an often awkward environment; all cables are easily terminated within the unit (now a BS requirement). The casing screws are captive, to prevent them falling to the ground. Special mounting brackets are also available that have been designed for use with the popular Unistrut system.
Micro beam technology
The Fire Beam utilises fresnel optics coupled with an optimised powerful infra-red diode. Because of this and advanced design technology The Fire Beam can be routed through more restricted locations with out misalignment or spurious reflections.
The Fire Beam ground level controller has been especially designed to take away the need for high level maintenance. With a simple menu system viewed through an LCD screen all adjustments can be made at ground level including a test procedure.
All of the following can now be completed at ground level:
Commission
The Fire Beam is commissioned by following a very simple procedure. You will easily align the beam having full confidence that the beam has correctly aligned itself on the centre of the reflector.
Adjust threshold
The Fire Beam's sensitivity is fully adjustable between 25 and 50%.
Check contamination compensation
The Fire Beam will automatically compensate for a build up of dust over the lenses. From the LCD display you can check the current status and only clean the lenses when required.
Time to fire and fault
The Fire Beam time to fire can be adjusted in 1 second increments between 1 and 30 seconds, and the time to fault can be adjusted anywhere between 1 to 60 seconds.
Change latching mode
The Fire Beam relays can be set to latch on alarm or auto reset depending on your individual requirement.
Turn on and off
The Fire Beam can be individually switched off if required. Should you forget to turn it back on it will resume normal operation after 8 hours.
Self test
The Fire Beam can be tested from ground level as part of routine maintenance.
Event count
The Fire Beam will record how many times it has fallen in to fault or fire since last reset.
Full diagnostics
The Fire Beam has a full in depth diagnostics facility, that can be accessed if required in conjunction with our technical help department. From here you can even find out the temperature of the beam head!
We have built into The Fire Beam protection system an IP rating of 65. The system is fully sealed against contamination ingress, which means that it is possible to place The Fire Beam in unfriendly environments and could even be pressure washed.
