Nice Era EPM photocells, relay, range 15 m

Nice Era EPM are photocells that stop or reverse the gate when someone or something interrupts the beam between the TX transmitter and the RX receiver. They have a conventional relay output, so they connect to the photocell input on the control unit. They are suitable for gate, garage door and door operators.

Which operators

Choose EPM if the control unit has a conventional photocell input. If the control unit supports the BlueBus interface, choose Nice Era EPMB. For greater safety, connect them to a control unit with the phototest function.

Wiring and setup

• Safety function – connect the wires to the NC contact (terminals 4 and 5). The NO contact (terminals 3 and 4) serves as a control device.
• 12 V power supply – on both the TX and RX boards, solder together the points marked “12V”.
• Distance over 10 m – on the receiver board, cut the “+10m” link.
• Two pairs side by side – to prevent interference, power them with alternating current, cut the “SYNC” link on the transmitters and wire one pair with the wires reversed. The reducing cone supplied also helps.

Things to consider before installation

The photocells cannot be aligned after installation, so the walls or pillars must be parallel. In fog or rain the range may drop by up to half. For narrow pillars, the Nice Era EPS slim with relay output are suitable. Send compatibility questions to eshop@saver.sk.
