Emerson TM115 Specification Guide

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.

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.

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.

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.

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.
