Hardware and Components
Two sizes of enclosures provide flexibility and expansion to meet evolving application needs. Both sizes of
enclosures come standard with a liquid crystal display (LCD) and controller board. In addition, the large
Universal Monitor has an internal Transformer Module.
The enclosure features a key lock for added security and is made of metal to accommodate secure conduit
fittings and protect components against environmental debris. The enclosure is designed for easy wire
routing and terminations, with top and bottom access slots for communication cables and network wires. The
enclosure is 2-3/4" deep, allowing for recess mounting in a wall.
Keypad Display
The keypad display is a user
interface mounted on the
enclosure door of each Universal
Monitor. The display provides
for complete monitoring and
configuration of the panel and is
password-protected.
The keypad display provides the ability for the
Universal Monitor to operate as a complete
standalone panel.
Controller Board
The controller board supports 22 points:
• Eight digital inputs
• Four analog inputs
• Eight digital outputs
• Two Common Alarm outputs
The digital inputs are dry contacts. The analog
inputs are 4-20mA inputs. The digital outputs and
Common Alarm outputs are Form C contact relays.
The point terminations are made using removable
terminal blocks. This allows for easier access to the
terminators, streamlining the process of connecting
external devices to the Universal Monitor.
The battery supplies power to the modem for a mini-
mum of 10 minutes, providing the capability to send
out a loss-of-power alarm to all configured pagers.
Flash ROM may be easily upgraded at the job site,
simplifying the process of installing new firmware as
it becomes available.
An RS232 operator terminal port is included with
each controller board for easy interface to a laptop or
desktop PC for setup and device monitoring.
An integrated on-board modem is included with each
controller board for remote access to the Universal
Monitor. An RJ11 phone modem jack is also
included. The modem is factory-configured, eliminat-
ing field configuration and wiring requirements.
An IGM422 connection is included with each control-
ler to connect the Universal Monitor to Liebert’s
SiteScan Web Enterprise Monitoring System. This
connection allows information and alarms to be mon-
itored from a centrally located command center.
Transformer Module
The large Universal Monitor
comes with either 115VAC or
230VAC Transformer Module.
• The 115VAC Transformer
Module provides step-down
power from 115VAC to
24VAC, two Class 2 24VAC
40VA power terminations
and one 115VAC outlet to
power accessory devices,
such as a Portable Operator’s
Terminal.
• The 230VAC Transformer
Module provides step-down power from 230VAC
to 24VAC and two Class 2 24VAC 40VA power ter-
minations. An outlet is not provided on this Trans-
former Module.
The Transformer Module may be ordered separately
as an option for the small Universal Monitor—or any
device requiring 24VAC—and mounted outside the
enclosure.
I/O Expansion Module
The Universal Monitor I/O Expansion Module, pur-
chased separately, has connectors for 16 digital
inputs and eight digital outputs, as shown below.
The board has light emitting diodes (LEDs) to dis-
play the status of monitored output devices, commu-
nications ports for connection to the Universal
Monitor, power connections and other features nec-
essary to monitor and protect your operation.
