Description
MPS-6 Power Supply
The MPS-6 is a supervised power supply
that converts 120 VAC, 60 Hz to unregu-
lated 24 VDC at 6A.
MPS-12 Power Supply
The MPS-12 is a high current power supply
that provides the MXL-IQ System with
primary 24 VDC power. It is rated at 12
amps and is unfiltered and unregulated.
The MPS-12 supplies the SMB-2 with the
power required for normal operation. The
module incorporates a 5 amp resettable
circuit breaker on the primary input, a 15
amp fuse on the 24V output, and a built-in
AC line filter for surge and noise suppres-
sion.
MKB Keyboard/Annunciator Panel
The MKB Annunciator communicates with
the SMB Main Control Board through the
System network link. This module provides
the MXL-IQ with its primary control and
annunciation.
The MKB modules have an LCD alphanu-
meric display that continuously updates
information about the System status and
user-defined device messages. If there are
multiple alarms, and/or troubles, including
supervisories and security conditions, the
highest priority event that occurred displays
first. The user can see additional alarm and
trouble data by pressing the NEXT key
(MKB-4) or the UP and DOWN keys (MKB-
6). Press the HOLD key (MKB-4 only) at
any time to stop the display from scrolling.
The Control Panel contains the following
indicators:
• Alarm
• Power
• Audible Silence
• Partial System Disable
• Supervisory
• Trouble
• Security
