GB 10408.3-2000Detectors for intruder alarm systems. Part 3: Microwave doppler detectors for use in building (English PDF)

1 Scope

This Standard gives the specific requirements and test procedures for microwave Doppler detectors for use in intruder alarm systems installed in buildings.

This Standard is an addition to the general requirements for detectors for use in intruder alarm systems as specified in GB 10408.1 Detectors for intruder alarm systems - Part 1. Requirements for detectors - General, and it shall also be used in conjunction with the standard for General requirements for alarm system, IEC Publication 839-1-1.

The object of this Standard is to specify those requirements for microwave

Doppler detectors which will ensure that they will perform satisfactorily and minimize false alarms.

IEC 839-1-3.1988 Section Three - Environmental testing

The tests may be carried out at any range within the range adjustment of the detector. The range control shall not be altered during the environmental tests.

The reference target shall move towards the detector from directly in front of the detector beyond the adjusted range at a speed of approximately 1 m/s. The distance from the detector when an alarm condition occurs shall be measure and recorded.

The distance from the detector where an alarm condition occurs after each environmental test shall not vary by more than 10% of the initial distance.

The tests may be simulated provided that it can be shown that the simulation gives the same results as the test procedure described.

For the following tests the detector shall be set for maximum stated range.

- electrical spikes;

- electrostatic discharge;

- electromagnetic fields.
