1 General
DI-9204Exd Digital Flame-proof Manual Call Point (MCP) is installed in vessels and
industrial explosion-proof areas. When there is fire, pressing the glass on this MCP,
alarm signal can be sent to fire alarm control panel (FACP).
The MCP can work at addressable mode to connect with GST’s series FACP that can
control fire suppression devices and transmit signal through loop. It can also work at
non-addressable mode to connect with 24VDC power and output fire alarm signal
through key switch.
The MCP is applicable to vessels, Zone 1 and 2 of explosive gas atmosphere and Zone
20, 21, and 22 of explosive dust atmosphere. It is also suitable for outdoor application.
2 Features
Using built-in microprocessor for alarm detection and output control. It features
stable operation and good protection against electromagnetic interference.
Electronically addressed. The address can be modified in field.
An independent output contact is provided to control periphery devices.
The MCP is reusable. You can press it to alarm, and reset it by a special key.
With wide temperature range, high ingress protection rating, the MCP can apply
to vessels, outdoors and explosivehazardous environment.

5.1.1 Installation of Base and Mounting Plate
The MCP consists of a base and an enclosure. Before installation, unfasten the four
screws and remove the enclosure from the base with care.
Connect the mounting plate and base with M5×8 cross recessed countersunk pan
head screws. Then fasten them to the wall with M8×60 expansion bolts.
5.1.2 Cabling
For MCPs with explosion mark Ex dII B T6, the cables are to be drawn in through
grommets. Thread the screened twisted pair with cross section not less than 1.0mm2
and outer diameter φ8mm-φ10mm through a metal washer and a grommet, screw
them all into the MCP enclosure, and thentighten the grommet with the thread using an
Allen key.
For MCPs with explosion-proof markEx dII C T6, the cables are to be drawn in through
flame-proof cable glands following the steps below:
(a) Strip an armored cable with cross section not less than 1.0mm2and outer
diameterφ8mm as shown in Fig. 3.
(b) Install the “Entrance Interface 3”and “Grommet 1”to the MCP body using an
Allen key.
(c) Thread the end of cable through “Nut 8”, “Grommet 7”, “Middle Sheath 4”,
“OuterWasher 6”, “Taper Washer 5”, and “Flame-proof Washer 9”in sequence,
and put the “Inner Sheath”of the cable inside the “Flame-proof Washer 9”of
the gland, cover the “Armor Layer”of the cable outside the “TaperWasher5”of
the gland, and then add the “Outer Washer 6”of the gland.
(d) Fill the uniformly mixed sealing filler between “Flame-proof Washer 9”and
“Taper Washer 5”, and then press the two parts tightly. Screw “Middle Sheath
4”onto “Entrance Interface 3”securely. Refer to Fig. 4.
(e) Finally screw and lock“Nut 8”onto “Middle Sheath 4”, as shown in Fig. 4.

5.1.3 Connection
There are terminals on the circuit board in the cover, as shown in Fig. 5.
K1 K2Z3 Z4Z2Z1
Fig. 5
Terminal description:
Z1, Z2: In addressable mode, connecting with signal cable, polarity-insensitive. In
non-addressable mode, connecting with 24VDC, polarity-insensitive.
Z3, Z4: Junction output for input signal of Z1 and Z2.
K1, K2: Volt free normally open output terminals. When the MCP is pressed, output
contact is closed to control external devices. These two terminals are optional that can
be used or not.
Connect the cables to the terminals in sequence.
(4) Final installation
After connection, put the cover into the base, and then fasten them with M5×10
Hexagon socket countersunk head screws.
5.2 Pole-mounting
The pole-mounted MCP is shown in Fig. 6 and dimension of the pole is shown in Fig. 7.
The mounting steps is as follows:
(1) Thread the cable through the cable outlet of the pole and the rubber washer.
(2) Install the pole on the ground using M10 anchor bolts.
(3) Screw down the cover, and lay out the cables according to the application
requirement with the same method as wall-mounting.
(4) Wire the MCP with the same method as wall-mounting.
(5) Connect the MCP base with the pole using M4X10 screw assembly.
(6) Install the MCP with the same method as wall-mounting.
