Installation and Operation
Installation must only be carried out by trained and skilled personnel. Please follow your local
regulations concerning installation.
!
Operation of the devices is not intended for personal, family or household use and applications.
The devices are supplied by SELV circuits (Safety Extra Low Voltage) in which hazardous voltages are not
generated. Thus, special safety measures are not required.
– The device must only be mounted in a vertical or horizontal position.
– Avoid selecting an installation position near ducts with dead-air space or areas with turbulence. Turbulence
mainly occurs near connecting flanges, branches, tight bends, and long, straight ducts. Place the device at a
distance of at least three times the width of the ventilation duct away from these critical areas.
– Air sample tubes must extend over the entire width of the ventilation duct.
Putting the devices into operation:
1. Mount the device including the air sample tubes and connect it to the fire system by wiring it to the LSN.
2. Set the device address.
3. Configure the device with the remote programming software (RPS) of the panel.
There are no restrictions of using the devices in commercial or industrial areas.
Permissible operation temperature is 0 °C to 50 °C.
