Receiver for optical anti-trap system

A bottom safety device prevents a closing door from trapping people, vehicles or objects. The system consists of an optosensor transmitter and an optosensor receiver. Both sensors are mounted opposite each other in the hollow bottom profile of the door.

During closing, the photoelectric sensor receiver continuously receives an infrared signal from the Transmitter. When the bottom rail is pressed down, the light beam between the two sensors is interrupted. The operator then stops the closing movement and immediately reverses the door’s movement.

Hörmann SKS receiver as a replacement part

If the existing photoelectric sensor receiver is faulty, it can be replaced separately. Always check the colour of the existing connection cable before ordering. This version has a black connection cable and is not compatible with photoelectric sensors fitted with a grey cable.

This photoelectric sensor is suitable for connection to a wired Hörmann S4 control unit. The receiver cannot be connected to a wireless control unit.

Part of the Hörmann S4 connection unit

The S4 connection unit for anti-drop protection can be used with suitable garage doors fitted with a Hörmann SupraMatic operator from Series 2 or 3. Connection to the operator is via the HCP1 bus port.

A complete S4 anti-trap system comprises, amongst other things:

• This Hörmann opto-sensor receiver
• Hörmann photoelectric sensor transmitter, item number 638248
• SKS Norm circuit board, item number 538573
• Suitable housing for the circuit board
• AT2 coiled cable with system plug, item number 436224
• Suitable hollow bottom profile for mounting the Sensors

The S4 connection unit is not suitable for Series 1 operators, as these do not have an HCP1 bus connection. Nor can the system be used with doors fitted with a wicket door.
