MAGNET TESTING: Place the magnet on top of the housing between the raised sections above the detector head (as indicated by the arrows on the unit cover). Allow at least five seconds for alarm initiation. Remove magnet and reset detector.
SMOKE TESTING: Using smoke test canister with testing nozzle (part number TG-2000 or ), insert the test gas nozzle into the test port on the unit cover. Press can against cover to release gas into the chamber. After 15 to 20 seconds the detector head will go into alarm, illuminating the detector head LED and causing the duct unit functions to operate, alarm relays will change state, and the alarm related remote accessories, if attached, will function. If no test gas is available to conduct functional testing, remove cover and, while holding down the cover removal switch, blow smoke from a cotton wick or punk directly at the head to cause an alarm. The alarm indicator should illuminate within one minute.
CAUTION: DO NOT SPRAY GAS FOR MORE THAN ½ SECOND. TEST GAS FACILITY MAY RESULT IN DETECTOR
CONTAMINATION.
After 15 to 20 seconds the detector head will go into alarm, illuminating the detector head LED and causing the duct unit functions to operate, alarm relays will change state, and the alarm related remote accessories, if attached, will function.
The S65A ionization detector head (55000-225APO) utilizes a radioactive source as its means of detection and will detect smoke particles of between .1 and 1 micron in size.
The S65A photoelectric detector head (55000-328APO) operates on the principle of light scattering
