Checking Procedures:
· Turn the power to the unit "On". Red LED light should illuminate at 8 second
intervals.
· Open the door to the hold open point. The door should hold open. Manually pull
door out of hold open and release. The door should close.
· Open the door to the hold open position. Press the Test / Reset Switch button on
the power supply board. Door should close.
· Press the Test / Reset Switch button again. Open the door to the hold open position. Inducing smoke into the
smoke detector chamber assembly will bring the unit into alarm. The red LED will be continuously illuminated and
the door will close. After clearing the smoke chamber, reset the unit as described below.
Resetting Instructions:
· Remote Reset: Cycle main power by turning the facility main power supply OFF
then ON. NOTE: If there are other units connected to the same power supply,
those doors will close.
· They will have to be reopened returning them to the hold open position.
· Local Reset: Insert a small flat head screwdriver through the cover and
· into the slotted light tube on the smoke detector as shown. Turn screwdriver
· slightly (about 1/8 turn) clockwise until hitting stop and hold for 2 seconds
· until the Red LED turns OFF. WARNING: Do not force past the stop.
· Doing so may damage the smoke detector.
· Once the detector is reset and the smoke has cleared, the detector's Red LED should
flash once every 8 seconds. The door(s) should hold open now.
Maintenance of Smoke Detectors:
It is recommended to clean smoke detectors at least every six months. The frequency of cleaning will depend upon
local ambient conditions.
The smoke detector in this door closer-holder has been enhanced with a feature that detects when a smoke-sensing
chamber requires cleaning due to dirt and dust. The need for cleaning is indicated by the flashing of the Red LED once
per second.
· Normal Supervisory Operation - Red LED flashes once every 8 seconds.
· Dirty Chamber needs cleaning - Red LED flashes once every second.
· Smoke Detection - Red LED is continuously illuminated.
To clean the smoke detector assembly, follow these instructions:
(NOTE: Before servicing the system, notify the proper
authorities that the smoke detector system is undergoing
maintenance and will be temporarily out of service. Disable the
zone undergoing maintenance to prevent unwanted alarms.)
· Remove detector cover and screen assembly using a
standard screwdriver. Turn the screwdriver in the cover slot
to loosen the cover and carefully rock the cover back and
forth until it snaps out of place. See slot location below.
· Inspect chamber for particles and dust. Vacuum the screen,
cover, and photo chamber. Then use clean, compressed air
to loosen and blow out any remaining debris.
· Before reassembling the detector, be sure all parts are free of
dust and debris.
· Replace cover and screen, aligning cover snaps. Press cover onto chamber until it snaps into place.
· Measure and record the test voltage at test points RP1 and RP2 (see below).If the smoke detector is operating
normally and was cleaned effectively, the test voltage will be greater than .90VDC and less than 1.58VDC.
The test voltage will increase with dust accumulation in the smoke sensing chamber. A difference in test voltages
over time will provide and indication of dust accumulation.
· Enable the system and inform proper authorities that system is operational.
