Oldham OLCT 80 Wireless Transmitter

  Frequency 2.4 GHz (EU) / 900 MHz (USA)
  Low Power Requirement
  Up to 3 km Line-of-Sight Range
  Robust Mesh Network Topology
  Up to 49 devices per network
  Flexible Input/Output options (analog, on/off, Modbus RS485)

Wireless connectivity is now possible in ATEX 1 zones thanks to the Oldham OLCT 80 Wireless Transmitter. The maximum range is 3km, line of sight. The number of field detectors, the area coverage and the network architecture will affect the type of network selected.

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).
