4 How to Use 4-3. Precautions for system designing Do not install the detector in a place where maintenance of the detector cannot be performed or where handling the detector involves dangers. Regular maintenance of the detector must be performed. Do not install the detector in a place where the machinery must be stopped when maintenance is performed in its inside, where parts of the machinery must be removed to perform maintenance, or where the detector cannot be removed because tubes or racks prevent access to it. - Page 16 4 How to Use 4-3. Precautions for system designing Proper use of alarm contact The alarm contact of the detector is used to transmit signals to activate an external buzzer, an alarm lamp or a rotating lamp. Do not use the detector for controlling purpose (e.g., controlling the shutdown valve.) The specifications for the alarm contact of the detector are based on the resistant load conditions.
