Transmitter and Receiver units are designed to work at 24V DC voltage (nominal) with variation between 19.2 V to 28.8V . The system works with carrier frequency 1800/2700 Hz and modulated frequency 65Hz/85Hz .
Transmitter and Receiver units are designed to work at 24V DC voltage (nominal) with variation between 19.2 V to 28.8V . The system is designed to work with carrier frequency 1800/2700 Hz and modulated frequency 65Hz/85Hz . For 1800Hz Carrier Frequency RED border is used in Front Panel and for 2700Hz Carrier Frequency BLUE border is used in Front Panel. Maximum power consumed by transmitter and receiver are 1.2W and 8W, respectively. Sense level for receiver is less than –19 dBm and No sense level for receiver is more than –22 dBm with 1mw (0 dBm) transmitter power. The equipment is designed to work satisfactorily with temperature variation from 0°C to 55°C with relative humidity of 95% at 35°C. Suitable test points are provided in the back of the equipment to monitor the necessary parameters.
