The CH4HR is a four-channel wireless receiver designed for use in radio remote control and access control systems. It features four relay outputs and is compatible with all Elmes 433.92 MHz band transmitters and wireless detectors. The receiver utilizes advanced KEELOQ dynamic code technology for enhanced security and supports both temporary (monostable) and bistable relay output modes, allowing flexible operation based on user programming.
The receiver is suitable for alarm systems and remote control applications, and it can be used as a set with a handheld transmitter or as a standalone receiver. The device is equipped with LED indicators for each channel and supports battery status monitoring for transmitters and detectors. When the battery in a transmitter is low, the receiver signals this condition via the S output and LED indication.
With the removal of jumper JP4, the receiver can function as a wireless mini alarm control panel, supporting up to eight wireless alarm lines and memory for up to 112 wireless devices. It also features anti-tamper protection and a dual-color LED for system status indication.
