UNBOXING

•  When unboxing the detector you will find the unit and its mounting base.
•  This comes with pre-formed mounting holes to mount the detector base and a securing screw

 on the base to ensure there is no unwanted removal.

For more information, please refer to the complete product manual.

IMPORTANT TO CONSIDER

When mounting a wireless device a comprehensive radio survey 
should have been carried out to establish the location that provides
the best coverage and optimum reach. Taking into consideration the building 
structure and materials, the survey identifies the wireless infrastructure
required and product locations for optimum performance, identifying
any factor that could prevent radio integrity.

Avoid fixing or mounting the unit close to the following: 
• Equipment that utilises large electrical currents
• Large metal objects or structures 
• Fluorescent lighting fittings 
• Metal ceiling structures 
• IT cabling.

Keep 2 meters minimum spacing between other wireless equipment
in the area to avoid signal interference.

EN54 approved environmental temperature range is -10°C to +55°C

• Remove the detector’s dust cover, intended to protect 

the unit during shipping.

• Remove the detector from the base twisting

anticlockwise.

Remove the battery compartment cover on the base
on the detector.

• A plastic pop out tag is removable from the base 

to enable you to label the address of the detector, 
prior to fixing to the ceiling: pop out the device label tag 
from the base and insert it into the side.

• Screw the base to the ceiling using all fixing holes

and appropriate-sized screws.
