About this deal

Alternatively, if you want to create an intelligent fire detection network in your building, you can use the XP95 Intelligent Manual Call Point, which is designed to work as part of a holistic fire detection system. This cover has a built in photoluminescent strip that glows in the dark. This ensures that, should the lights fail in the event of a fire or emergency, there will be no delay in reaching the button.

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.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. BRE Global report finds compatibility between NFPA 72 code, EN54 standards". FMLink. 2010-06-04 . Retrieved 2023-02-05. It is vital that, in the event of an emergency, all fire call points can be easily reached – no one should have to travel over 45m to reach an alarm call point, and in environments where a fire could spread rapidly, the maximum distance is shortened to 20m. Like a CPU (central processing unit) in a computer system, the fire alarm control panel is the brain of fire alarm system which sends a status indication and notification to the connected detectors and sounders in case of manual or automatic operation.

For an extra 45p, you can select the tamper seal version of this cover from the dropdown menu above. This is designed to further deter unauthorised or malicious use of buttons and break glass units. One break seal is supplied with this version. More break seals are available in the related products below.

Testing the same call point – you have to test a different call point every week, otherwise the tests won’t be even. Usually, they are located along the escape routes, near the fire exits, so that you can trigger the alarm without slowing down the evacuation process or putting yourself in unnecessary danger. According to the relevant regulatory requirements ( BS 5839), call points should be placed: There are two chambers in a typical ionization smoke detector. The first chamber is used to compensate the changes in ambient temperature, pressure or humidity while, there are alpha particles (radioactive material) in second chamber which is used to ionize the passing air in the chamber where current flows between two electrodes. In case of fire when smoke enters the chamber, the current flow between two electrodes reduced due to ionize air. The drop in the current flow is used to trigger the sounder and alarm circuit. Light Scattering Smoke Detector 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.As compared to the traditional fire alarm systems, they only provide single signal of info i.e. no matter if it is a fire, or other uncertainties such as fault, temperature, smoke particle or barometric pressure etc, it will trigger the alarm system which is considered as false positives. This misleading information can affect different phenomena such as reporting, omission etc. Usually, close to the fire exit at 1.4m height to make sure that they are easily accessible to everyone, including wheelchair users.

White manual call points: Since those don’t indicate a single function, there should be additional signage telling you what this particular call point does. However, there’s one thing white manual call points can’t be used for and that’s to call the fire services

Ionization Smoke detectors work based on lowering the current flow through the inside chamber due to ionization which leads to initiate the alarm. A fire alarm call point (also referred to as a red manual call point or a break-glass call point) is essentially a small box, mounted on a wall which contains a button or a lever that allows you to manually trigger the fire alarm in a building.

Break Glass solution

Many modern fire alarm pull stations are single-action and only require the user to pull down a handle to sound the alarm. Other fire alarm pull stations are dual-action, and as such require the user to perform a second task before pulling down, such as lifting or pushing in a panel on the station or breaking a glass panel with an attached hammer. Perhaps the most recognizable pull station is the "T-bar"-style pull station, so named because the handle is shaped like the letter "T". This style is manufactured by many companies, most notably SimplexGrinnell. An emergency break glass, for example, allows building occupants to signal that a fire or other emergency exists in the premises. They are usually connected to a central fire alarm control panel which is in turn linked to the building's alarm system. A manual call point can be mounted either in a stairwell or on a floor; the important thing is that the call points are on the emergency exit route and the individual activating the manual call point does not need to deviate from the emergency route when activating the alarm.
