Note: Refer to the 4098 Detectors, Sensors, and Bases Application Manual
(574-709) for detailed information on Detectors and Sensors.
Sensor Magnet Test
The following test method is suitable for functional checks of sensor bases
during installation; however, testing with aerosol must be performed to comply
with NFPA requirements.
Position the 553-810 Magnet Tester on the cover side, below either of the arrow
marks (see Figure 16), not between the two arrow marks. Testing a sensor
with a magnet reports a value of 255 for actual / peak (exception 4010 panel).
Clear the peak value after testing.
Detector Magnet Test
The 4098-9601 photoelectric detector may be tested by placing a magnet at the
location indicated by a “TEST” mark embossed on the cover for four (4)
seconds (see Figure 16). Use the Simplex Magnet Tester (Part No. 553-810),
Table 4, and the following information to test detectors.
Figure 16. Magnet Test Location
Table 4 describes the Detector LED reaction during Normal and MAG TEST
modes to the Normal, More Sensitive, Less Sensitive, and Non-Functional states
of the detector.
