Model MKB-4
Annunciator/Keypad Module
Fire Safety
The SIEMENS Model MKB-4 Annunciator/Keypad
provides the MXL-IQ/MXL System with its primary
control and annunciation. The MKB-4 communicates with the SMB-1/2 or the MMB-1/2 Main
Control Board through the System network link.
OPERATION
The MKB-4 has an 80-character, backlit LCD
alphanumeric display that continuously updates
information about the System status and user
defined device messages (See Figure 1). If there
are multiple alarms and/or troubles that include
supervisories and security conditions, the MKB-4
displays the highest priority event that occurred.
The user can see additional alarm and trouble
data by pressing the NEXT key. Press the HOLD
key at any time to stop the display from scrolling.
There are switches for the following functions:
Acknowledging fire alarms
Silencing audibles (AUD SIL)
Acknowledging supervisories (SUPV ACK)
Acknowledging troubles (TRBL ACK)
Acknowledging security conditions (SEC ACK)
(ALARM ACK)
specific menu-driven operations as well as
programming and maintenance functions.
Another series of switches located on the MKB-4
allows the user access to the MXL-IQ/MXL
Control menu. There are also System status
indicator LEDs. The ALARM and TROUBLE
LEDs function even if the main processor fails
(See Figure
1).
There is also a separate key for resetting the
Control Panel (RESET).
The 10-digit numeric keypad allows entry of the
three levels of user passwords. It also does

INSTALLATION
Remove all system power before
installation, first battery and then AC.
(To power up, connect the AC first
and then the battery.)
Unpack the MKB-4. Inspect the module for such
things as integrated circuits (ICs) not firmly
seated in their sockets, bent IC pins, connectors
not properly installed, dirt, and packing material
on the board.
Setting the Network Address
(See Figure 2)
1. Before installing the MKB-4 panel, set its
network address on S1, the switch on the
ANN-1 board located on the back of the
MKB-4. Use dipswitches SW1 and SW2 on
switch S1 to set the network address of the
MKB-4. Refer to Table 1 for switch settings.

Setting Supervision
2. The MKB-4 module address is always set
within network addresses 248 through 251.
3. One supervised MKB-4 must be installed
at network address 251. Other supervised
MKBs may be at the other addresses.

Use switch S1-SW5 on the ANN-1 to select or
deselect supervision. If your ANN-1 has a switch
with position 1 indicated on the left-hand side,
ignore the printing on the switch. SW1 on S1 is
at the extreme right-hand side of S1, regardless
of any other marking.
To set for supervision
S1-SW5 = Closed (ON)
To set for non-supervision
S1-SW5 = Open (OFF)
NOTE: When you select non-supervision for an
annunciator, there must also be one
and only one supervised annunciator at
the same address. The supervisory
mode is independent of the network
address.
NOTE: Switches S1-SW3 and S1-SW4 are for
future use. Switch S1-SW5 is used to
select supervision.

Mounting the MKB-4
(Refer to Figures 3 and 4)
To mount the MKB-4 in an MSE-3/3L enclosure:
1. Install 3 screws in the first group of 3 tapped
holes in the right flange as shown in Figure 3.
Leave a 1/8-inch gap between the head of
the screw and the flange. Slide the slots of
the MKB-4 panel hinge under the head of the
screws and tighten.
2. After the MKB-4 is mounted to the enclosure,
connect the cable (P/N 555-192238)
between P1 on the ANN-1 (on the back of the
MKB-4) and P8 on the SMB-1/2.
CAUTION: Be sure the black tracer wire on
the edge of the cable is close to
the 1 on position 1 of connector
P1 on the ANN-1 and the 1 on
position 1 of P8 on the SMB-1/2.
To mount the MKB-4 in an EBX-1/-2 backbox:
1. Install the XEA-1/-2 adapter plates and
brackets in the EBX-1/-2 backbox according
to the XEA-1/-2 Installation Instructions, P/N
315-093608.
2. Mount the MKB-4 on the right bracket using
the hardware supplied with this module as
shown in Figure 4. Install 3 screws in the 3
1
tapped holes in the right flange. Leave a
/8inch gap between the head of the screw and
the flange. Slide the slots of the MKB-4 panel
hinge under the head of the screws. Adjust
the position of the MKB-4 so that the module
opens smoothly and closes securely against
the magnet. Tighten the screws.
3. After the MKB-4 is mounted to the enclosure,
connect the cable (P/N 555-192238) between
P1 on the ANN-1 (on the back of the MKB-4)
and P8 on the MMB-1/2.
CAUTION: Be sure the black tracer wire on
the edge of the cable is close to
the 1 on position 1 of connector
P1 on the ANN-1 and the 1 on
position 1 of P8 on the MMB-1/2.
