Hörmann HER 4 BS relay receiver, 4-channel, BiSecur, 868 MHz

The Hörmann HER 4 BS controls up to four devices: gate operators from Hörmann and other manufacturers, lighting or other electrical appliances. Each relay has its own function, which you set with DIL switches. With the HS 5 BS transmitter you can see whether a relay is switched on.

Relay functions

• Impulse – the relay switches for 0.5 s, for example for a gate operator.
• On/off – the first command switches on, the next switches off.
• Light for 3 minutes – the relay switches for 3 minutes, for example for yard lighting.
• Adjustable impulse – set the impulse length according to the manual.

Things to consider when wiring

The relay contacts can handle 2.5 A at 30 V DC or 500 W at 250 V AC (resistive load). Do not mix up the supply voltage; doing so will destroy the electronics. Leave 230 V wiring to an electrician or to our service in the Košice and Prešov regions. A smaller receiver for two devices with a 12–24 V DC power supply is the HET/S 24 BS; the transmitter with status feedback is the HS 5 BS. Send questions to eshop@saver.sk.
