LEAN CARS CSR-12T-1B 12V BDM-0925 Control Unit

Managing access to gates, garage doors, and roller shutters often means juggling multiple remotes or dealing with unreliable receivers. The LEAN CARS CSR-12T-1B 12V BDM-0925 control unit solves this by acting as a single, dependable radio receiver module that works with Elmes Electronic 433.92 MHz transmitters. It gives you a secure, rolling-code connection and flexible relay output, so you can automate entry points without complexity.

Who is it for

This receiver is ideal for homeowners, property managers, and installers who need to add remote control to existing automation systems. It suits gate automation, garage door openers, roller shutters, and access control setups. If you already use Elmes 433.92 MHz transmitters or need a reliable receiver for a new installation, this unit fits the bill.

Main features

• Operates on 12V DC, compatible with common automation power supplies.
• Receives on 433.92 MHz with KEELOQ® dynamic code for rolling-code security.
• Single-channel relay output, configurable as normally open (NO) or normally closed (NC).
• Stores up to 112 transmitters in memory, enough for a large household or small business.
• Three operating modes: monostable, bistable, and timed (adjustable from 1 second to 4 hours).
• Low standby current of about 10 mA, with relay active current around 30 mA.
• Supports internal or external antenna connection for better range in difficult installations.
• Simple screw terminal connections for power, relay, and antenna.

Tips

To maximize range, connect an external antenna tuned for 433.92 MHz if the receiver is mounted inside a metal enclosure. When programming transmitters, follow the manufacturer's instructions for KEELOQ® rolling code to ensure security. For timed mode, test the relay duration with a multimeter or connected device to confirm the desired interval.
