6.3.6 Magnetic Test for photoelectric detectors
Test the 4098 Photoelectric Detectors by placing a magnet above the location indicated by a “|” mark embossed on the cover for 4
seconds. Use the Magnetic Tester, Part No. 553-810, Table 14, and the following information to test the detectors.
Table 14 describes the LED reaction during Normal and MAG TEST modes to the Normal, More Sensitive, Less Sensitive, and Non-
Functional states of the detector.

When placing the magnet at the location indicated by a “|” mark embossed on the cover, the visible LED flashes indicating the condition of
the detector.
The following are descriptions of the detector when it is in MAG TEST:
• NORMAL - When in MAG TEST, the detector latches into alarm if the detector is within calibration range and the visible LED stays ON.
• MORE SENSITIVE - When in MAG TEST, if the detector is more sensitive than the maximum calibration, the visible LED quickly flashes,
twice a second. Following the sixth flash, the detector latches into alarm and the visible LED stays ON.
• LESS SENSITIVE - When in MAG TEST, if the detector is less sensitive than the minimum calibration, the visible LED slowly flashes four
times, once every two seconds. Following the fourth flash, the detector latches into alarm and the visible LED stays ON.
• NON-FUNCTIONAL DETECTOR - If the detector is less sensitive than the minimum permitted sensitivity, or if there is a fault in the
temperature sensing circuit (4098-9602), the visible LED does not flash normally. When in MAG TEST, the visible LED slowly flashes
four times, once every two seconds. After the fourth flash, the detector does NOT latch into alarm, the LED stops flashing and turns
OFF.
If the detector is outside the normal operating range, clean it. If after cleaning the detector still indicates an abnormal sensitivity, replace
the detector.
