                                   Figure 1. TrueAlert Is Module 

Warning:

   Make sure that all power is disconnected before starting the installation. 

 

Caution:

   Connect Wiring to terminals as shown.  Do not loop wires under terminals. 

Break wire runs to provide supervision of connections. Do not bring conduit 
through the rear of the electrical box. Strip lead insulation to 3/8” maximum. 

1.

 

At the electrical box, connect the contractor wire to the PORT 1/PORT 2 (+ and -) terminal of 
the TrueAlert Is Module. See figure 2 and 3, TrueAlert Is Class B and A 
Wiring. 

2.

 

Ensure that correct polarity is maintained across the ports. 

3.

 

Ensure that the CKT +’s or -’s are not crossed between ports. 

4.

 

Do not loop wires under the terminals.
