Liebert Universal Monitor 用户手册

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.

Power switch for the controller board. When switched off, 

the battery pack is disabled.

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).

Indicates the connection status between the Universal 

Monitor and SiteScan Web.

Provides audible notification when an alarm occurs.

N/A

Jumper to disable the audible horn (factory default is 

enabled).

N/A

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. 

Each output has an LED to indicate its status: ON/OFF 

(energized/de-energized).

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.

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. 

Indicates the operational status of the controller board.
