Fire Safety
The
SIEMENS
Model
MKB-4 Annunciator/Keypad
provides the MXL-IQ/MXL System with its primary
control and annunciation. The MKB-4 communi-
cates 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
(ALARM ACK)
Silencing audibles
(AUD SIL)
Acknowledging supervisories
(SUPV ACK)
Acknowledging troubles
(TRBL ACK)
Acknowledging security conditions
(SEC ACK)
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
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).
