Controller Board Overview
The Universal Monitor’s controller board has connectors for eight digital inputs, four analog inputs
and eight digital outputs, as shown below. The board comes complete with light emitting diodes
(LEDs) to display the status of monitored devices, a battery pack for short-term backup, communica-
tions ports, power connections and other features necessary to monitor and protect your operation.

Description
For more information, see:
A - Power On/Off
switch
Power switch for the controller board. When switched off,
the battery pack is disabled.
B - Battery pack
Provides battery backup during a power loss to maintain
normal operation of the panel for a minimum of 10 minutes.
The analog inputs will not be functional during a power loss
(P/N 133455P1).
2.4.3: Connecting the Battery Pack
Indicates the connection status between the Universal
Monitor and SiteScan Web.

N/A
F - Common Alarm
connectors
The two common alarm connections are used to connect to
a secondary warning device such as a horn, light or
Building Management System (BMS). When an alarm is
present, the contacts close and the external warning device
is activated/notified. The common alarm contacts may be
configured to be reset with the Silence button/command.
G - Digital output
status LEDs
Each output has an LED to indicate its status: ON/OFF
(energized/de-energized).
H - Manual Override
Switch (outputs)
Placing the switch in the ON position will turn ON, or energize,
all eight outputs simultaneously. This switch removes all
automatic output control from the Universal Monitor.
I - Digital output
connectors
Each of the eight output connections is a two-state point:
ON/OFF (energized/de-energized).
An example of a field digital output point is a motor starter.
4.2.2: Connecting Digital Outputs
J - Status LEDs
