Conventional Products—2412, 2412TH, 2424, and 2424TH Direct Wire Photoelectronic Smoke Detectors 13
Direct Heat Test (Models 2412TH and 2424TH only)
To test the bimetallic thermal collector on the models 2412TH and
2424TH, follow these instructions:
1.
Use a low powered heat gun or blow dryer, and aim the heat source
across the detector.
2.
Hold the heat source about 12 inches (30 cm) from the detector to
avoid damaging the plastic. When the heat rises to greater than
135°F, the detector will latch in alarm.
3.
After the test, the bimetallic collector will self-restore.
Detectors that fail these tests should be cleaned as described in the
Maintenance section of this technical bulletin and retested. If the detectors
still fail these tests, they should be replaced or returned for repair.
Notify the proper authorities that the system is back online when tests are
complete.
