Description

DC-9101E Conventional Combination Heat Photoelectric Smoke
Detector, non-addressable, is a kind of combination detector consisting of
smoke sensing parts and semi-conductor heat sensing parts in
technological structure and circuit structure.

Together with DP-9907, it can connect to conventional fire alarm control
panel or connect with intelligent fire alarm control panel through I-9319
Addressable Zone Monitor Unit conduct the processing of detector
signals. The detector has the advantages of both conventional
photoelectric detector and rate of rise and fixed temperature heat detector.
Just because of the combination of smoke detector and heat detector, it
overcomes the non-sensitivity to dark smoke particles of ordinary
scattering photoelectric detectors. It can also pick up fire with obvious rise
of temperature such as alcohol flame, thus extending the application
range.

Connection and cabling

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 remote indicator
4: Negative terminal of remote indicator

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.

Installation

Fix the flame retardant base with two taping screws. Then align A on the
bottom of the detector to B of the base, and rotate the detector clockwise
to mark C (Refer to Fig.1 and Fig. 2 for mark A, B, C).
Mounting of the detector is shown in Fig.3.

Application

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.

The sensitivity level 1 is defaulted, which can be modified by P-9910B
programmer. Refer to P-9910B Hand Held Programmer Installation and
Operation Manual for details.
In power-on state, input unlocking password and press Clear to unlock.
Press Function, then number “3”, the screen shows “-” at the last digit.
Input corresponding sensitivity or parameter and press Program, the
screen will show a “P”, the corresponding sensitivity or parameter is
programmed. Press Clear to clear the "P". Input locking password and
press Clear to return.
Rate of rise and level 1 is defaulted.

 When the detector connects with conventional fire alarm control
panel or addressable zone monitor unit from GST, and if DP-9907 Active
End of Line Unit is connected to the end of output loop, DB-01D base
should be used.

 Used as the detector base, DP-9907 Active End of Line is

used to be installed a conventional detector on it. The system
connection is shown in Fig. 4.

 When DP-9907 Active End of Line Unit is not used as the
detector base, a cover should be added to it. The system
connection is shown in Fig.5.

panel or the addressable zone monitor unit from GST, if a 4.7KΩ
terminal resistor is connected to the end of output loop, then DB-01 base
is used. The system connection is shown in Fig. 6.

 When a remote indicator connects with a few of detectors, a diode

1N5819 needs connecting with Terminal 4 of the orientation base in
series and with anode of the remote indicator. The system connection is
shown in Fig. 7.

Fig. 7
Output loop of the addressable zone monitor unit can be connected with
up to 15 conventional field devices. The addressable zone monitor unit
features loop checking. When the loop is broken, the addressable zone
monitor unit will send fault signal to fire alarm control panel. When any
field device in the output loop is removed, the addressable zone monitor
unit reports fault. If a DP-9907 Active End of Line Unit is connected, it will
not affect the normal operation of other field devices.

Testing

Before testing, please ensure that the detector has been installed
correctly and powered up. After 10 seconds, testing begins.

1. The detector must be tested after installation and periodical
maintenance.

2. Testing method

1) Magnetic test
Test zone is shown in Fig. 8. Put the magnet of commission tool close to
that of the detector and hold on for a few seconds until the detector
generates alarm.

Test Zone

Fig.8 Fig.9

2) Smoke test
Taking a cotton rope burning without flame close to the detector, blow the
smoke into the detector until the detector generates alarm.

3) Temperature test
Approach a heater (such as a hair drier) to the thermistor of the detector
until it alarms.

3. After testing, cut power for 10 seconds at least and reset the detector.
Notify the proper authorities that the system returns to normal state.

Clean the failure detector in the test according to Maintenance, and test it
again. If it is still fail to pass, please return it to repair.

Maintenance

1. The detector should be installed just before commission and kept well
before installation, taken corresponding measures for dust-proof,
damp-proof and corrosion-proof.

2. The dust cover cannot be removed until the project has been plunged
into usage. Otherwise it can’t alarm normally.

3. Clean the detector at least once a year to ensure normal operation of
the system.

4. If nuisance alarms are often found of the detector on site, the sensing
chamber should be cleaned and replaced when necessary.

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. 9.

b) Clean the sensing chamber by alcohol cotton swab clipped by

tweezers, and also by clear water and brush. Please note not
to leave any cotton in the chamber.

c) Install the sensing chamber and top cover back.

5. 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.

6. The detector should be tested again after cleaning and re-installing.

7. Fire simulation test should be made to the detector at least once half a
year.
