Universal four relay outputs receiver (U4HR)* and sets (U4HS & U4HSL)* are designed for use in alarm systems and remote control applications. The sets consist of U4H receiver and one four buttons hand held remote control transmitter. The devices use KEELOQ dynamic coding technology and the receiver operates with all Elmes made 434 MHz radio band transmitters and wireless detectors including specific RP501 transmitter made by Elmes Electronic.
Receiver operation
Activating transmitter stored in receiver memory results in setting on respective relay output and LED indication in the receiver. Depending on programmed operating mode, the output may be set on temporarily for earlier programmed time period (monostable mode) or set on until next signal is received from transmitter in on/off mode (bistable mode). These are two basic output modes relating to operation with most transmitters. However, in operation with Elmes RP501 in its radio relay mode (mode 3) or CTX3H and CTX4H wireless magnet detectors operating in open/close detection mode, the receiver relay output set on state lasts until set off signal is received, regardless of the receiver output programmed operating mode.
