3.5 Safety and security sensors
The units are fitted with safety and security sensors, which monitor persons passing the door wings
and also perform a safety function.
The Multibeam safety and security sensor system consists of 16 (24 on the long version and 29 on
the long high version) infrared transmitters and receivers. The transmitters and receivers are
operated in such a way that each individual receiver will only respond to its designated transmitter.
This makes the system insensitive to sunlight, fluorescent lighting or other light ‘pollution’. The
Multibeam and MCB communicate through a RS-485 link.
Children (<= 35 ½ inch or 900 mm) are not detected by the security sensors, but are detected by
the safety sensors between the doors. The emphasis is on maximising safety and not on access
security. The safety sensors are placed (at 7 inch or 180 mm and 23 inch or 580 mm from finished
floor level) to ensure optimal safety.
