DIP-Switch Coded Long-Range RF Transmitter

The ENFORCER HL-Series RF transmitters and receivers offers significantly increased range with greatly increased immunity to interference, whether physical obstacles, temperature extremes, or other environmental factors. DIP-switch coding allows you to easily program multiple transmitters with the same code and easily change the code later if needed. This can be very useful for job sites, gated communities, and any situation where multiple users need to control the same receiver.
