Back Check

Back check is a function within the door closer that provides resistance to prevent the door leaf from being violently thrown open. The back check action can help prevent damage to the door, door frame, walls and door handles that can be caused when a door is kicked or thrown open rapidly. Back check will cushion and slow down the door when it reaches approximately 90°.

Please Note: The back check facility can put additional strain on the door hinges - it is recommended that fire doors are fitted with 3 hinges, one at the top, one in the middle and one at the bottom.

Beam Detector

A beam detector is used to provide "wide area" smoke detection and is usually used in situations where it is either not practical or not cost effective to use traditional point detectors. A beam of light (usually infra-red) is projected across the area to be protected, any smoke entering the beam cause the beams power to fall, when the power falls to a predetermined level the detector will signal an alarm.

End to End Beam Detectors

An end to end beam detector consists of a transmitter and receiver, these are positioned at opposite ends of the area to be protected. The transmitter emits a signal, which is detected and monitored by the receiver.

Reflected Beam Detectors

A reflected beam detector contains the transmitter and receiver in the same unit (transceiver). The transmitter emits a signal which is reflected back to the transmitter using a reflector positioned at the opposite end of the area to be protected.
