In alarm systems, sensor placement is one of the most critical elements directly affecting system performance. Incorrectly positioned sensors can create blind spots, give false alarms, or fail to detect a real threat. Therefore, sensor placement must be planned and done professionally.
Why is sensor placement important?
Thanks to the correct placement:
-
No blind spots are formed.
-
Detection distance is used efficiently.
-
The risk of false alarms is reduced.
-
Maximum security is ensured.
Not only the number of sensors, but also their location determines security.
Where should the motion sensor be installed?
Motion sensors typically:
-
To the corner of the room
-
To face the entrance direction
-
2 – 2.5 meters in height
must be assembled.
The air conditioner should be placed near a window and away from direct sunlight.
Magnetic Contact Placement
Magnetic contacts:
-
to the opening of the door and window
-
The magnet and the sensor should be parallel.
-
within a distance of 1-2 cm
should be placed.
A false alarm may occur if the door alignment is not correct.
Glass Break Sensor Location
Glass break detectors:
-
Angle to see the glass
-
Usually to the opposite wall
-
Suitable distance for coverage of 6–9 meters.
must be assembled.
It should not be placed behind furniture.
Smoke Detector Placement
Smoke sensors:
-
To the center of the ceiling
-
Away from the air current
-
Keep away from air conditioner and extractor fan outlets.
must be assembled.
It is not recommended to place it directly inside the kitchen.
Where should the gas sensor be installed?
The altitude varies depending on the type of gas:
-
Near the ceiling for natural gas.
-
Ground level for LPG
-
For carbon monoxide, the intermediate level
should be placed.
Incorrect altitude detection reduces performance.
Flood Sensor Location
Water sensors:
-
To the ground
-
Under the combi boiler
-
Under the sink
-
To the lowest point in the server room
should be placed.
The sensor leads must be exposed to water.
Outdoor Sensor Placement
Outdoor sensors:
-
Securely fixed to the wall.
-
It will not be exposed to direct sunlight.
-
Stay away from objects swaying in the wind.
It should be positioned.
The height is usually between 1 and 1.5 meters.
How to Prevent Blind Spots?
To avoid blind spots:
-
A site survey should be conducted.
-
Furniture placement should be considered.
-
The sensor's field of view must be calculated.
-
Multiple sensors should be used if necessary.
Professional planning is essential.
Is Zone Planning Important?
Yes.
If the areas are divided into separate zones:
-
It is clearly seen which section was triggered.
-
False alarm analysis becomes easier.
-
Intervention time is shortened.
This is especially important in workplaces.
Why is a professional assessment necessary?
Every place:
-
Square meter structure
-
Ceiling height
-
Number of divisions
They are different.
Planning should be done after the survey at the standard site location.
