  OLCT 80 Wireless WirelessFixed Detector Wireless field detector and transmitter for detection of oxygen, combustible, toxic and refrigerant gases in remote locations Now Available in Wireless! KEYBENEFITS • Suitable design for use in explosive areas • Reduces installation costs by eliminating cabling and wiring • Available with flameproof or from distortion or interference Lower Installation Costs Eliminating the need for point-to-point wiring, the operation of the OLCT80 wireless is as simple as one single field device communicating intrinsic-safety sensors • wireless connectivity in ATEX 1 zones. Providing a range of up to 3km the OLCT 80 utilises binding technology to ensure that the signal is free On-board display allows noninvasive one-man calibration • The new OLCT 80 model builds on an established design to provide It can be linked via secure network to monitor large remote areas with a controller, remote display and alarm station. Signal Processing you can Rely on The transceivers operate at a universally accepted frequency of 2.4 GHz and have the capability to transmit signal data from various inputs or GASESANALYSED serial MODBUS outputs.
