Tips For Positioning - Watchguard N517Series II User Manual

2.5.1. Tips for positioning

• This detector utilises the very latest in detection processing technology to reduce
the possibility of false alarms. However, correct mounting of the detector is critical
to ensure best detection or "catch" performance. You cannot just screw the detector
directly to a wall up high in a corner and expect best performance. Thoroughly
walk test each detector, and if detection is not acceptable in the location you have
chosen, adjust the angle of the detector slightly & re-test. You will find that a slight
up/down angle change may improve catch performance significantly.
• Mount the detector on your wall using the swivel mount provided at a minimum
height of 1.2 metres and maximum of 2.1 metres (lower is better). Make sure the
detector is a minimum of 5 metres away from your main unit so it doesn't swamp
the receiver with a signal that is too strong to decode.
• Always mount your PIRW so that an intruder has to walk across its zones, i.e. walk
past the detector, not towards it.
• DON'T mount detectors facing glass doors or windows. Always mount above
windows and doors to look inside.
• DON'T mount detector facing hot areas or areas where the temperature may
change suddenly, e.g. open fire places, direct sunlight or air conditioning vents.
• Select a location where the detector can provide the best detecting range. Always
ensure that you do not cover an area with multiple detectors, so as to avoid
