Wireless 433MHz


The Wireless 433MHz Receiver provides a fast and simple integration of ICT 4 or 2 button remote transmitters into any alarm or access control system. Alternatively, standalone functionality allows for easy, secure operation of gates or other access areas where convenience is required.

  • 3 operating configurations: Wiegand, RS-232, and standalone 
  • 4 open collector programmable outputs
  • 1 Form C relay Output
  • Programmable reception sensitivity for each channel
  • 600 user (transmitter ID) capacity in standalone configuration
  • Unlimited user capacity in Wiegand pass through configuration


The Wireless 433MHz Receiver can be utilized in a range of applications, including:

  • Vehicular gate operation
  • Apartment complex access control
  • Building/home automation functions
  • Remote security system control

The wireless receiver's Wiegand and RS-232 pass through configurations enable you to use ICT wireless transmitters as credentials in a Protege or third-party access control system, allowing access control of up to 2 doors.

In this configuration the wireless receiver passes all transmitter data through to the integrated system. The control panel determines whether the user has access, and unlocks the relevant door.

Standalone configuration allows the wireless receiver to function independently, controlling a single door such as a remote carpark gate. In this configuration the receiver determines whether users have access, and controls the door using the onboard relay output.

Several methods are provided to restrict user access:

  • Program up to 600 individual Transmitter IDs, either through the terminal interface or by automatically adding each detected button press
  • Specify a range of Transmitter IDs which will be accepted
  • Restrict access to a specific site code

The wireless receiver provides the user with two different programming interfaces:

  • Programming via RS-232 Serial connection to a PC
  • Built in terminal menu to access all options

The onboard relay and open collector outputs provide flexible control options for access, alarms or automation functions.

  • Use the relay output to control a door or provide a panic, duress or medical alarm.
  • When not used for Wiegand pass through, up to four open collector outputs are available for other functions, such as activating lights and buzzers or monitoring user activity ('man down switch').
  • Each output can be individually configured for NO or NC operation.

The optional SMA antenna accessory allows for greater flexibility when positioning the wireless receiver. The 3m long cable allows you to install the module in a secure location such as a cabinet while placing the antenna in the open for maximum wireless
coverage. The antenna also has a magnetic base for convenient attachment to the outside of the cabinet or another metal surface.

The SMA antenna can be ordered via the following product code: RF-RCVR-433-ANT
