Description
DC-9101 (IS) Intrinsically Safe Conventional Combination
Heat Photoelectric Smoke
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. It's
applicable to zone 1 and zone 2 of areas with explosion-proof
requirement in petroleum and chemical industries. It can
match with fire alarm control panel, I-9332 Interface,
explosion-proof detector and end-of-line resistor produced by
GST to conduct the processing of detector signals. The
detector has the advantages
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
4: No connection.
Recommended Cabling
2
1.0mm or above fire cable. The capacitance distributed
among cables should not be over 0.083μF, and the
inductance distributed should not be over 4.1mH. Laid out
through metal conduit or flame-retardant conduit, subject to
local codes.
Installation
Fix the base with two tapping screws, and then align mark A
on the detector bottom with B on the base, rotate the detector
to align mark A with mark C (Refer to Fig. 1 and 2 for the
position of the marks), the detector will be fitted to the base.

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.
Note: Programming should be done in safety zones
because handheld
non-intrinsically safety devices.
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.

If the detector connects with fire alarm control panel, I-9332
interface and other exposition proof products in series, a
4.7kΩ end-of-line resistor should be connected to the end of
loop. System connection is shown in Fig. 4. Note the polarity
of power line.
