CORTEX RT4-5se radio alarm transmitter
Main features:
CORTEX RT4-5se is designed for collecting information from guarded object, processing and transmitting it to the central alarm receiver through radio channel. Also, CORTEX RT4-5se controls external power supply. If there was no change of information in the inputs of object device during certain period, the test message is delivered to control the device. The object device RT4-5se has 6 inputs and additional function - control panel mode.
CORTEX RT4-5se object device has three modes of operation:
- Parallel input mode. The object device performs in this mode as six-input translator, i.e. transmits any change of input status to the central alarm receiver.
- Serial interface mode. When in this mode, the object device uses synchronized serial interface to receive data (Z1 input - clock, Z2 - data) and can transmit up to 8 bytes of information to the central alarm receiver. This allows to receive detailed information (alarm types, users Ids, ect.) from control panels, using simple additional devices, and to transmit it to the central alarm receiver.
- Control panel mode. Attention! This mode is activated by the manufacturer and cannot be switched by the user. If control panel mode is switched on, the other two modes cannot be switched on. Attention: the jumper should not be installed between the contacts.
Object device RT4-5se is set in a closed metal block.
RT4-5sa is a modification of the object device RT4-5se. The technical parameters are the same, except for carrier power: RT4-5se-5W, RT4-5sa-0.5W.
