Mounting

NOTE: Use minimum 18 gauge wire for all customer interface wiring.

The MR1 Mini-Remote is completely tested, then shipped from the factory disassembled for your convenience during installation. To begin flush-mount installation, please refer to Figure 2A. An optional 30-foot control cable can be supplied to allow the display to be located remotely from the electrical box. Refer to Figure 2b.

The electric box containing the power supply is designed for flush-mounting into a finished interior wall. A wall plate is supplied to cover the drywall opening, with the display mounted directly in front of the wall plate/electric box.

1.Mount the electric box (Item 5) in the wall at a convenient location.

2.Make each power and unit connection (to Item 4) by inserting bare wire end into compression terminal and tightening screw. Refer to Electrical Connections section. If 30-foot cable is used, disconnect factory wire harness and attach cable to screw terminals per Figure 2.

3.Route control cable through wall plate and electric box cover, then connect to electrical box at TB1 (on Item 4).

4.Attach electric box cover (Item 3) with two (2) screws.

5.Remove the front cover from the MR1 display panel (Item 1) by gently prying open at the slots on the top and bottom of the display. Attach the control panel rear plastic and the wall plate (Item 2) to the electric box with two (2) screws.

6.Snap display panel front onto the rear plastic part.

7.Apply power to the MR1. Operate the system to test status and alarm monitoring, and customer selected options including on/off control. Also test optional customer interface (4 inputs and 1 output), if applicable.
