INSTALLATION
BEFORE INSTALLING
NOTICE: This manual should be left with the
owner/user of this equipment.
IMPORTANT: The detector must be tested and
maintained regularly following NFPA 72 requirements.
The detector should be cleaned at least once a year.
GENERAL DESCRIPTION
Models DG311 is photoelectronic detector uses a state
of-the-art optical sensing chamber. This detector is
designed to provide open area protection and to be used
with most conventional fire alarm control panel.
Two LEDs on each detector provide local 360° visible
alarm indication. They flash every 3~5 seconds indicating
that power is applied and the detector is working properly.
The LEDs latch on in alarm. LEDs will be off when a
trouble condition exists indicating that the detector
sensitivity is outside the listed limit. The alarm can be
reset only by a momentary power interruption.
INSTALLATION
NOTE: All wiring must conform to applicable local
codes, ordinances, and regulations.
NOTE: Verify that all detector bases are installed, that
the initiating-device circuits have been tested, and that the
wiring is correct.
Remove power from initiating-device circuits before
installing detectors.
1. Wire the sensor base per the wiring diagram, Figure 1.
2. Install the sensor into the sensor base. Push the sensor
into the base while turning it clockwise to secure it in
place.
3. After all sensors have been installed, apply power to
the control unit.

4. Test the sensor(s) as described in the TESTING section
of this manual.
5. Notify the proper authorities that the system is in
operation.

Warning ：
Forbid
current-limiting resistance. Otherwise, the detector would be burnt out.
Dust covers are an effective way to limit the entry of
dust into smoke detector sensing chambers. However,
they may not completely prevent airborne dust
particles from entering the detector. Therefore, We
recommends
the
removal
beginning construction or other dust producing
activity.
Be sure to remove the dust covers from any sensors
that were left in place during construction as part of
returning the system to service.
