Proteco RF33 Wireless Photocells
1 x Wired RX Receiver & 1 x Wireless TX Transmitter Safety Photocells
The Safety Photocells are wireless in respect of the transmitter unit only. This provides a solution to avoiding laying extra cable across the drive way to connect the transmitter. The transmitter & receiver can operate over a range of up to 20m.
The receiver unit remains hard wired to the control board, much like our wired safety photocells. The receiver unit must be hard wired to ensure permanent communication to the control board at all times. This reduces the risk of “broken communication” if another wireless signal was to interfere and create “cross-talk” (conflict of communication between numerous devices).
For example, if the control board did not receive the correct signal transmitted from the photocell receiver when it was needed, the gate(s) would fail to respond to the presence of the obstacle detected.
