    3.0 Installation 3.1 Monitor Placement Coverage Guidelines for placement of diffusion type monitors are based on the reasonable delay for gas to get from the source to the sensor. All monitor sensors combinations are created equal in this regard. • For air quality control of exhaust emissions and accumulations of toxic gases the generally acceptable maximum radius of coverage is 50 feet (15 meters).
  • Page 9 3. Heavier than air: HFCs, HCFCs, Propane (C Chlorine (CL 2 ), Hydrogen sulfide (H 2 S), most organic vapors (consult Belimo): Install 1 to 2 feet (0.3 to 0.6 meters) from floor. For all types of monitors avoid drafts, obstacles, aerosols, silicones.

The bottom left corner of the display will indicate a 1 and the alarm 1 LED will light up. In addition, the Alarm 1 Transmit Message (default is 1) will be sent to all monitors and Communication modules via the CAN network.

  • Page 26: Network Configuration

    5.0 Network Configuration 5.1 Using CAN Network with a Central Communication module A communication module serves as the central connection point for the ventilation system. Model 22Gxx-5y gas monitors transmit alarm commands to the central communication module. A communication module will display up to 32 monitors on the network.
  • Page 27 5.2 Using CAN Network with No Central Communication module (client/server) One of the 22Gxx-5A or 22Gxx-5B series monitors can be used as the communication module. It can activate the ventilation for all the sensors, or a group. The use of a dedicated communication module is optional;...

  • Page 28: Defaults Configuration

    5.3 Default Configuration Monitors are shipped pre-loaded with default settings which can be changed in the field to suit the desired sequence with simple keypad input. When a monitor goes into alarm level 1, 2 or 3 it activates its relays and transmits a message to other sensors to activate their relays also.
  • Page 29 The communication device has no sensors on board so the relays will only activate if it sees it’s receive codes on the network. The Communication module could control two zones via its two relays. When no Communication module is used, the master monitor(s) needs to be a member of the group it is controlling.

  • Page 30: Maintenance Guide

    6.0 Maintenance Guide All monitors are shipped from the factory pre-calibrated. To maintain accuracy and conformity with standards it is essential that they be calibrated by a qualified technician once or twice per year, depending on the application. 6.1 Calibration Procedure Use certified precision gas mixtures (with regulator tube and cap) to adjust the sensitivity of the sensor due to normal aging and guarantee that the designed alarm set points are respected.

  • Page 31: Calibration Procedure For Refrigerant

    8. Inject bottled span gas (using regulator, tube and cap) into first sensor and wait until the gas reading stops going up. The span gas used must be within the range of sensor’s scale. 9. Adjust the reading up or down to match the concentration in the bottle 10.
