Description
The photocell FT35C has been designed and created for use on power operated gates or doors. It has autotest function, usable with control units able to manage it.
- The Safety Photocells are a safety feature designed to keep the gates open/closed when the beam is broken by a pedestrian/ vehicle.
- Easy to install
- Offers additional peace of mind
- An additional pair of wired Safety Photocells can be added to cover both sides of the gates, inside and outside.
The product comprises of a pair of Safety Photocells, a transmitter and a receiver, these are installed either side of the door or gate opening, this creates an infra-red beam, if the beam is broken the door or gate will not operate or if it is moving it will stop or stop and reverse, dependent upon the control unit.
The transmitter has a normally closed contact input for connection of a Safety Edge, when the Safety Edge is activated the Safety Photocell receiver operates in the same way as if the infra red beam was broken.
The Safety Photocell’s are normally positioned either side of the opening at a height of about 600mm, the Safety Photocells have a range of approx 40m although this can be reduced by up to 70% in cases of misalignment or difficult climatic conditions.
The Safety Photocell’s can be installed either in-front of the gates, behind the gates or for additional safety both in-front & behind the gates. By placing the Safety Photocells in-front of & behind the gates it provides further protection in the closing phase of the gate operation, if either infra-red beam is broken whilst the gates are closing the operation will halt.
