Safety Photocells

CAME active infra-red safety beams are invisible to the naked eye, but can be transmitted from a ëDOCí transmitter up to 18 metres in outdoor conditions to a ëDOCí receiver. These represent an excellent form of positive ìbeamî protection around the gateway and on wing type gates they are normally installed in two sets, one just in front of the gate line and one just inside the arc-line of travel described by the swinging wing of each gate. In this way, a safety zone will have been created, so that on the automatically timed closure of the electric gates, if a vehicle is still within the area of travel of the gates, it will prohibit the gates closing and furthermore, if a ìbeamî should be broken after the automatic closing has begun, it will re-open and hold the gateway open until the obstruction is clear.
