Description
EDC-M9102 Conventional Photoelectric Smoke Detector (the
detector) is a new-generation product by building in a
microprocessor, embedding a solid fire analyzing program, and
performing effectively and efficiently.
Checking a fire alarm signal, the detector will send it to a fire alarm
control panel (FACP) or addressable zone monitor unit by means of
current changes. The detector indicates its fire condition by turning
on fire LED and keeping the LED on until it is reset.
Using infrared scattering technology, with an innovative chamber,
the detector receives very weak infrared light under normal
smokeless condition. If smoke particles enter the chamber, the
received light signal will increase by scattering. When smoke
density reaches certain density, the detector will output fire signal. In
order to reduce interference and power consumption, the emitting
circuit works in pulse mode to prolong the life of IR LED.

Please install the base according to the following steps:
1) Locate the mounting holes on the rubber seal of the base
according to the holes on the electrical junction box, and
punch the holes with a screwdriver.
2) Count the number of cables needed and punch correct
number of holes with a screwdriver on the rubber seal at the
cable entry position. Thread the cables through the cable
entry holes.
3) Install the base onto the junction box with screws.
Warning: Do not punch mounting holes and cable entry holes
bigger than needed. Do not punch more holes than needed.
There are four terminals with numbers on the base.
1: Detection zone positive IN
2: Detection zone positive OUT
3: Detection zone negative IN and OUT
2: Positive terminal of alarm output
4: Negative terminal of alarm output

Recommended Wiring
1.0mm2 or above fire cable for all terminals laid through metal conduit
or flame proof conduit, subject to local codes.
Note: Different color cables are used to avoid wiring mistake.
Up to 25 conventional devices can be connected to a
module/FACP. See next page, compatibility section, for
detector capacity per circuit
Installation
Refer to D Series Detector Application Bulletin for additional installation
instructions.
Fix the base with two taping screws. Then align A (Fig.1) on the
bottom of the detector to B (Fig.2) of the base, and rotate the
detector clockwise to mark C.
Mounting of the detector is shown in Fig.4.

Warning: The alarm current depends on the current limit of the
control panel. 24VDC cannot power the detector directly.
Otherwise the detector will be blown up for lack of current limit
resistor.
Testing
Before testing, please ensure that the detector has been
installed correctly and powered up. After 10 seconds, testing
can begin.
Before testing, notify the proper authorities that the system is
undergoing maintenance and will temporarily be out of service.
Disable the zone or system undergoing maintenance to avoid
unwanted alarms.
All detectors must be tested after installation and periodically
thereafter. Testing methods must satisfy the Authority Having
Jurisdiction (AHJ). Detectors offer maximum performance when
tested and maintained in compliance with NFPA 72. The detector
can be tested in the following way:

Test zone
Fig. 5 Fig. 6
1) Reed Switch Testing
Magnet test zone is shown in Fig.5. Put the magnet of commission
tool close to the zone of the detector and hold on for a few seconds
until the detector generates alarm.
1) Smoke test
The Trutest model 300 Aerosol Smoke Detector Tester can be used
for smoke entry testing. Set the generator to represent 4%/ft to 5%/ft
obscuration as described in the Trutest manual. Using the bowl
shaped applicator, apply aerosol until the panel alarms.
Additionally, canned aerosol simulated smoke (canned smoke agent)
may be used for smoke entry testing of the smoke detector.
Recommended aerosol smoke products are:
Manufacturer Model
Trutest AERO400
When used properly, the canned smoke agent will cause the smoke
detector to go into alarm. Refer to the manufacturer’s published
instructions for proper use of the canned smoke agent.
2) After testing, cut off the power above 10 seconds and reset the
detector and then notify the proper authorities that the system is
back in operation.
Warning: Canned aerosol simulated smoke (canned smoke agent)
formulas will vary by manufacturer. Misuse or overuse of these
products may have long term adverse effects on the smoke detector.
Consult the canned smoke agent manufacturer’s published
instructions for any further warnings or caution statements.
When testing is complete, restore the system to normal operation
and notify the proper authorities that the system is back in operation.
Maintenance
1. The detector must be cleaned once a year to ensure normal
operation of the system.
2. Before cleaning, notify the proper authorities that the system is
undergoing maintenance and will temporarily be out of service.
Disable the zone or system undergoing maintenance to avoid
unwanted alarms.
Chamber Clearing Steps:
a) Open the top cover of detector, and draw out the sensing
chamber by slightly lifting its two sides using a straight
screwdriver, as shown in Fig. 6.
b) Use a vacuum cleaner or cleaned, compressed air to
remove dust and debris from the insect guard and the sensing
chamber. The sensing chamber can also be cleaned by clear
water and brush. Put the sensing chamber in clean water to
brush the dust inside and take out to dry it.
c) Install the sensing chamber and the top cover back.
Cautions
1. Dust covers can’t be removed until the project is put into use
formally. Take well care of dust covers for future use.
2. Dust covers effectively but not absolutely prevent dust particles
from going into detectors. So, we recommend that detectors
should be removed prior to construction, decoration, or other
activities producing dust. The proper authority should be informed
of detectors removing.
3. Be careful not to damage the detector in maintenance.
The smoke detector may not sense fire that where smoke cannot
reach it, such as in chimneys, in walls, on roofs, or on the other
side of closed doors.
4. The detector cannot monitor the place beyond protection area.
5. The detector may not warn you about fires caused by
insufficient safety measures, violent explosions, leaking gas,
improper storage of flammable materials like diluents and other
safety hazards, arson or children playing with fire.
6. The alarm of a smoke detector used in high velocity
environment will be delayed due to dilution of smoke by frequent
and fast airflow.
7. Smoke detectors have their own service life. In order to keep
the detector working in good condition, please maintain them
according to recommendations from manufacturers and relative
state standards.
8. The detectors must be tested regularly, at least once a year.
9. Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found suitable for
that purpose.
