The Pelco LRD41C212 Legacy Fixed Speed Receiver (24 VAC Input) transfers control data and video on the same line, and supports 8 alarm inputs/1 alarm output. Storing up to 64 preset positions, the unit can sequence between the alarm presets when multiple alarms are activated. The alarm contacts connected to the receiver can activate up to 8 presets and the alarm inputs can activate an external device via an open collector output. The receiver can operate up to 2 remotely activated auxiliary functions.
The unit has a standard 15-bit or extended 32-bit command protocol making it compatible with Coaxitron control systems, and uses D- or P-type protocols for Pelco series RS-422 control system. The receiver includes a control without video feature, which detects the controller's Coaxitron commands when no video signal is present. The transient suppression reduces the interrupted operation or damage caused by sudden voltage spikes on the power and signal lines.
For camera synchronization, the unit comes with an additional electrical (coax) connection to the camera, which is useful when multiple cameras require frame synchronization. It also includes standard features such as self-test diagnostics and auto/random scan.
The legacy receiver is designed for use with the Legacy LWM41 wall mount that has a bottom opening for easy access and installation. It is compatible with fixed speed Legacy pan/tilt models such as the PT780P, PT780P/PP, PT780SL, PT780SL/PP, PT780-24P, PT780-24P/PP, PT780-24SL, and PT780-24SL/PP.
