With the aid of the battery-driven microprocessor, the service device performs a
large part of the task autonomously. During testing, the status and error registers of
the compatible devices are queried and tested. In the case of optical point
detectors, the signal intensity of the infrared LEDs in the measuring chamber is
also tested.
Wireless communication between the service device and the compatible device is
based on electromagnetic induction. The devices reply with optical signals. The
communication synchronization is controlled with the control impulse of the internal
alarm indicator of the compatible device.
