Application

The analog input module (MPC-8AI) is an expansion 
module that plugs directly into any of the four option 
slots available on the TAC MicroSmart Multi-purpose 
Controller (MSC-MPC), providing additional analog 
inputs to the MSC-MPC.

The MPC-8AI provides eight universal analog inputs 
that can be configured as 1000 ohms Balco, 1000 ohm 
platinum, 4-20 mA, 0-11 Vdc sensors, or status contact 
inputs.

SPECIFICATIONS

Model No.

MPC-8AI.

Agency Listings:

UL-916,

Energy Management Equipment.

UL-873,

Temperature Indicating and Regulating 

Equipment.

UL-864,

Smoke Control System Sub-assembly. 

Complies with FCC Class “A” requirements.

Warning:

Listed as a smoke control system sub-assembly. 

Not to be used by itself or as part of a TAC MicroSmart 
Control Network (RCM/NCM) in a smoke control application. 
For smoke control applications, install in accordance with F-
25645, “TAC DMS Smoke Control Systems Manual”.

Installation Guidelines

FCC Guidelines

This equipment has been tested and found to comply with the 
limits for a Class “A” digital device, pursuant to Part 15 of the 
FCC rules.

These limits are designed to provide reasonable protection 
against harmful interference when the equipment is operated 
in a commercial environment. This equipment generates, 
uses and can radiate radio frequency energy and, if not 
installed and used in accordance with the instruction manual 
may cause harmful interference to radio communications. 
Operation of this equipment in a residential area is likely to 
cause harmful interference in which case the user will be 
required to correct the interference at his own expense.

Pre-Installation

Warning:

To reduce risk of fire or electrical shock, install in 

a controlled environment relatively free of contaminants.

Before beginning the installation process for the MPC-8AI, 
visually inspect the unit for any obvious defects and to make 
sure all parts are included. If any flaws are detected, contact 
your local TAC office or authorized representative 
immediately.
