Signal Processing

Suitable for a wide choice of industrial detection and alarm system applications, the OLCT 80 is ideal for transmitting signal data.

Transceiver operates at a universally accepted frequency of 2.4 GHz / 900 MHz and is able to transmit signal data from its analog or Modbus outputs.

The wireless version of the OLCT 80 eliminates wiring costs and is very easy to commission in the field. The device can be associated with our MX 43 control panel, touch screens and audible or visible alarms.

Wireless network integrity, security and reliability are guaranteed by using FHSS technology (Frequency Hopping Spread Spectrum).
