11. Mounting the door/window contact sensor
‘FHT80TF-2’
To save you from having to laboriously read through several user manuals we have included
information on how to mount and start up the ‘FHT80TF-2’ door/window contact sensors on
the following pages.
The ‘FHT80TF-2’ door/window contact sensor is not supplied with the ‘FHT80B-3’
and must be purchased separately!
a) General information
Magnetic contacts (reed contacts) are integrated into the left and right sides of the casing of
the ‘FHT80TF-2’ door/window contact sensor. These enable you to mount the magnets
supplied with the ‘FHT80TF-2’ on the left or on the right.
In addition, the screw-terminals inside the ‘FHT80TF-2’ allow external contacts to be attached.
These external contacts must be NC (normally closed) contacts.
When a door or a window is opened, the contact must be open.
Three different operating modes are available:
• Only the internal contact is monitored
• Only the external contacts are monitored
• Internal and external contacts are monitored
Please note:
The door/window contact sensor should only be installed in dry indoor areas.
Do not install the device on or near large metal objects (radiators, mirrors, metal
doors, aluminium laminated walls in pre-fabricated houses) as this can reduce the
wireless range.
