Door Industry Journal - Spring 2017

Also online at: www.dijonline.co.uk THE door industry journal spring 2017 fire & security Depending on the installation and level of protection required, there are a variety of fire door retainers readily available which react to different triggers, in the event of a fire. Hard wired fire door retainers Hard wired fire door retainers are used all over the world and are ideal for new buildings as they have a direct wire connection to the building’s fire detection system. In a normal condition, power (usually 24 V dc) is supplied to the door retainers so that they can hold the doors in an open position. When a fire is detected by the fire panel, power is cut releasing the doors so that they can close. A fault in the wiring or power supply to the door retainers will cause them to fail safe and release the doors. Hard-wired fire door retainers are available in many shapes, sizes and finishes to suit all applications. Radio controlled fire door retainers Radio controlled fire door retainers are triggered wirelessly by radio waves from a controller connected to the existing fire panel or interface unit. As minimal wiring is needed, these are often used for fitting into large, existing buildings but still offer high levels of protection. These systems are installed by an approved, trained professional as a site survey has to be carried out prior to installation. Sound activated fire door retainers Sound activated fire door retainers react to the noise of the fire alarm and some devices can learn the sound of the building’s specific fire alarm, so they will only release when the alarm sounds. This is a cost effective solution as there is no need for wiring to a fire panel. Sound activated fire door retainers are battery powered and can be installed quickly and easily. They are wire-free, so installing them won’t affect a building’s infrastructure.
