1 Pack of 5 Replacement Break Glass for Fire Alarm Call Points

Product Information

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. 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; The multi sensor detector (also known as multi-criteria alarm) is a sensitive device which combines the input signal from both heat and optical sensors and used for wide range of fires with lower rate of unwanted false alarms.

Extra loud 105 decibel alarm will sound as soon as the cover is lifted. This will attract the attention of all those around and act as a significant deterrent to the would-be perpetrator.NFPA 72 National Fire Alarm and Signaling Code® § 3.3.12 Alarm Box.

These are some of the different types of covers you can choose from:

Manual call points can have more than one function. They come in three colours: white, green and red. The different colours indicate the function of each individual call point: The Break glass fire alarm manual emergencycall point for fire alarm system and access control system A light source and a photocell are fixed in a darkened chamber where direct light doesn’t fall on the surface of photocell.

Auditing should be enabled if available, to log details of the account usage and details of the work carried out while using the account. Some systems may recognize emergency accounts and raise the system auditing level or increase audit logging of only the emergency accounts. Emergency Accounts should be created in advance to allow careful thought to go into the access controls and audit trails associated with them. The following factors should be considered: 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.

Systems for use during construction can be wireless or mechanical. In the United Kingdom, interconnecting wireless systems are recommended for timber-framed construction. [9] European Standards [ edit ] 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 access solution should be used only when normal processes are insufficient (e.g. the helpdesk or system administrator is unavailable). Examples of situations when ‘break glass’ emergency access might be necessary:Due to their use for life inherent purposes, radio receivers used in such systems should be of Category 1 [8] standard. Testing the same call point – you have to test a different call point every week, otherwise the tests won’t be even.

Physical Barrier - prevents anyone accidentally or intentionally leaning against break glass device Designed to prevent accidental and malicious false fire alarms, SSP’s Direct range of call point covers, break glass covers and push button covers are ideal for use in schools, colleges, nursing and care homes, hospitals and shopping centres. 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 DetectorA 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. Another interesting fact about manual call points is that they should always be installed on the floor side of an exit door leading to a staircase so that when the alarm is triggered, the alarm system can correctly identify which floor the fire has occurred on. 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.
