The detection zone tests allow you to determine the distance at which the detector will detect alarms. In test mode, the light indicator lights up continuously, switching off during the alarm. In order to determine the detection area, use the device light indication as a guide

DeviceProcedure of testing
In order to check the opening detector at the suggested installation place, open and close the door/window. If the detector responds to all actions, it is installed correctly.

In order to check the motion detector, walk across the room, following the LED reaction, and determine the detector detection area. Maximum motion detection distance is 12 meters.

If the detector does not always respond to the motion during the test, it should be mounted elsewhere.

Contains motion detector and sensor masking tests.

  • In order to check the motion detector, walk around the premises while observing the LED and determine the detection zone of the detector. If the detector does not always respond to the motion during the test, it should be mounted elsewhere.
  • In order to check the masking sensors, block the view of the detector. For example, with an opaque A4 sheet of paper. If the detector does not respond to masking, contact the Ajax support service.

The glass break detector registers an alarm if it detects two components: a low-frequency component (sound of impact against glass) and a high-frequency component (impacts of shards against each other).

Therefore, in order to check the glass break detector, bang the hard surface with your fist (preferably the glass plane, but without breaking it). The detector must respond to the low-frequency sound of the impact against the glass, turning off the LED for 0.2 s. If this happens, throw a metal object (for example, a spoon) at the hard surface or hit it with a glass tumbler within one and a half seconds. The detector will turn off the LED for a second; this means that in armed mode the glass break detector will normally respond to the glass breaking. Decrease the detector sensitivity and keep checking until the detector stops responding to the alarm sounds. After this, bring the sensitivity level back to the previous limit at which the detector responded normally. In this way, the probability of the detector being falsely triggered is minimized and at the same time provides reliable protection for the facility.

To provide maximum protection against false triggering, turn on all appliances that usually operate in the room: generators, air conditioners, etc.

If switching on these devices intermittently causes the detector to activate, its installation place should be chosen more carefully.

Combines MotionProtect and GlassProtect testing procedure.

If the detector responds poorly to the alarms during the tests, it is necessary to choose another location.
