GST C-9201 User manual
30303705 Issue 3.04
Features
Reusable button, that can be reset manually;
Providing an independent output contact;
Plug-in structure.
Description
C-9201 (Ex) Explosion Proof Manual Call Point (MCP)
is installed in public places. When there is a fire,
pressing the nearest MCP, alarm signal can be sent to
the fire alarm control panel (FACP). And the control
panel will show the code of I-9332 Interface
connecting with the MCP, and give alarm sound.
The MCP is operated by pressing the mechanically
latched button to reduce possibility of accidental alarm.
There is a LED on the MCP, which is used to indicate
its status.
Connection and Cabling
Terminals of the MCP are shown in Fig.1.

Connection:
I1, I2: Connecting to intrinsically safe side of the
Safety Barrier
K1, K2: Normally open output terminals
O1, O2: Connecting to the next MCP
Recommended Wiring: Selecting intrinsically safe cable
with cross section not less than 1.0mm2 , and the
capacity assigned among cables should not be over
0.04μF, the inductance assigned not over 4.3mH. All
wiring must be installed in compliance with the local
codes.
Installation
Unplug the MCP, thread the cable through the cable
entry of the base box and connect it to corresponding
terminals, and plug the MCP back. The base of the
MCP can be surface or flush mounted as shown in
Fig.2 and Fig.3.

Warning: Before installing the MCP, disconnect the
power from the loop and verify that all bases are
securely installed and that the wiring polarity is
correct at each base.

Explosion Proof Manual Call Point
30303705 Issue 3.04
Application
Explosion Proof Manual Call Point is intrinsically safe,
which is designed for flammable and explosive locations,
such as petroleum and chemical industry. When the
MCP is connected with I-9332 Interface, explosion-proof
photoelectric smoke detector, and explosion-proof rate
of rise and fixed temperature heat detector in series, a
4.7kΩterminal resistor should be connected to the end
of the output loop. Its system wiring is shown in Fig.4.

Notes:
The total number of explosion proof detectors
and explosion proof manual call point to be
installed should not be over 10.
Never carry out maintenance in field with power
on. Please operate according to corresponding
regulations.
Products passed the explosion-proof test should
not be replaced; furthermore, the components
and the structure which would affect
explosion-proof performance should not be
modified without authorization.
