If you happen to uncover a fire at work, sounding the fire alarm using a manual call point is the fastest way to get your colleagues’ attention and prompt them to get to safety. If the fire isn’t big enough to have triggered the automatic fire detection system, your proactive actions could help put the flames under control before the fire has had the chance to spread. Indoor and outdoor call points – Weatherproof Fire Call Point Covers are perfect for outdoor environments or damp places like swimming pools as they provide access to the call point, without allowing any moisture to corrode the call point fire alarms.

Usually, the user will break the glass and press the emergency button centred in the middle of the unit. This will then activate a centralised alarm system to alert building wide that there is an emergency. Previously, the old British standard did not allow hinged covers and plastic resettable elements. Plastic elements must have the same printing as the EN 54 glass. There’s always something new you can learn to improve your fire safety knowledge and today we’ll look at yet another key element of your fire detection system – the manual call points (MCP) used to activate your fire alarm. From what they actually do and where to find them to using and testing them correctly – here’s everything you need to know about fire alarm call points. In the US and Canada, alarm initiating devices with button-like designs are sometimes used in high-hazard occupancies. The NFPA 72 standard uses the term Alarm Box, which could encompass a number of initiation mechanisms. [3] A few manual call points have been approved to UL/UL Canada standards. [4] [5] At the time of this writing, the pull station is still the most prominent design in this part of the world.In a typical conventional fire alarm system, detectors, sounder and call points are installed and divided into different zones i.e. Zone 1 for basement, Zone 2 for ground floor, Zone 3 for first floor etc. This way, it is easy to identify the exact affecting area to the control room, building management and fire brigade. In other words, the more numbers of zones, the more accurate locating the trigger and fire location. When you activate the manual call point, it sends a signal to the fire system’s control panel, notifying it that there is a fire in the area closest to the call point. As a minimum, this will sound the fire alarm throughout the building. It should also start the fire emergency protocols, including calling the fire brigade.

Physical Barrier - prevents anyone accidentally or intentionally leaning against break glass device Maintained within sealed envelopes, where a broken seal would be an obvious indication that the accounts have been accessed; Kept behind glass in a cabinet, where access to the accounts requires literally breaking the glass (similar to a fire extinguisher or alarm), providing an obvious indication that the accounts have been accessed and a deterrent to casual use; Light obscuring smoke detectors work based on measuring the amount of light falling on the surface of a photocell.

A report by the UK-based Building Research Establishment (BRE) stated "there is a commonly held view that equipment designed to meet the European EN54 Fire detection and fire alarm systems standard cannot be used within an installation designed to the US National Fire Alarm Code, NFPA 72." In actuality, "there appears to be no requirement in NFPA 72 that precludes the use of manual call points..." [6] An older Legrand Manual call point. This call point uses a lever-shaped key to reset.
