Testing
The D300A-HV photoelectric detector has a built-in sensitivity window verification feature. If
the detector is within its calibrated sensitivity range, the detector LEDs flash green in standby
or normal operation. If the detector drifts outside its sensitivity range, the LEDs flash red to
indicate an out of sensitivity condition. Bosch D1000 Calibrated Smoke Detector Tester may
also be used to check sensitivity.
4.2
Replacing the Detector Head
If the detector head supplied with the D300A-HV must be replaced, only replace the existing
head with a D282A-DH Replacement Photoelectric Smoke Detector Head.
