Beam smoke detection is a cost-effective alternative to point detection in large open spaces such as factories and warehouses.
Depending on the size of the area, one or more infra-red beams are projected in a continuous line across the protected area e.g. at high level along the length of a roof structure.
Obscuration of the beam path by smoke particles will trigger the beam detector.
Fixfire® offers Intelligent beam detectors which automatically realign in order to compensate for structural building movement. These units feature a low level controller with digital read-out display and simple user functions.
Beam detectors offer reduced maintenance costs as not only will one detector cover an area which would otherwise require significantly more point-type detectors, but the problems of accessing detectors at high level are avoided.
KeyCall® is a revolutionary patent-granted Key Operated Fire Alarm Activation Device which has been developed specifically for ‘approved’ applications where standard fire alarm call points would be vulnerable to abuse. Developed by Fixfire® in response to growing demand from the Mental Health Care sector, KeyCall® is a revolutionary one-piece analogue addressable key operated manual call point.
Compatible with a wide range of Conventional and Addressable Fire Alarm Systems.
KeyCall® accepts a Euro-Profile style cylinder
Typically suited/keyed-alike cylinders are fitted so that authorised persons can activate KeyCall® using their standard door key.
Key ‘Click-latch’ mechanism ensures key ‘latches’ in correct position to activate Fire Alarm System.
Anti-ligature low-profile flush-mounting design.
Neat minimalistic one piece construction incorporating Fire Alarm interface module.
Red fire indicator illuminates when KeyCall® is activated.
Compatible with a wide range of Conventional and Addressable Fire Alarm Systems
Applications include:
- Prisons
- Mental Healthcare
- Special Educational Needs (SEN) School

Beam Detector at high level
British Standard Design requirements...
- Install AFD to voids greater than 800mm
- Treat downward projections exceeding 10% of the void depth as wall
BS5839-Part 1:2013 states:
22.2d) If the system Category is such that automatic fire detection should be provided in any area that contains a horizontal void of 800 mm or more in height, automatic fire detection should also be provided in the void.
22.3j) Ceiling obstructions, such as structural beams, deeper than 10% of the overall ceiling height should be treated as walls [see Figure 10a)]. NOTE 10 Within horizontal voids, beams or obstructions that are deeper than 10% of the overall depth of the void regardless of whether the void is above the ceiling or below the floor, ought to be treated as walls that subdivide the void.
