ways.

Navigate to the controller’s Input Status screen and 

highlight the board and point that you wish to map. Press 
F1 to go to the Input Setup screen for that board/point. 
Each point will increase incrementally to correspond with 
each board. (

For example, where the MRLDS is address 1 

and the MRLDS address is 100, use board 1, point 1. For 
an MRLDS address of 101, use point 2.

REFLECS Setup for IRLDS IIs

Set dip switch 8 to ON and follow the steps for setting 

up IRLDS IIs through the REFLECS controller interface: 

1.

Log on.

2.

Press 7 for 

Configuration

 to reach the 

CON-

FIGURATION

 screen.

Input Definitions should be set here to show how the 

sensor control is linked to the zone. The number of devices 
and IRLDS IIs are connected to the Gateway and enabled 
is the number of address slots the Gateway will use.

3.

Press 1 for 

Input Definitions

 to reach the 

INPUT DEFINITIONS

 screen.

4.

Pressing the down arrow several times will 
get you to the input list of 

SENS01-48

Bd

 

(board) is the address of the Gateway, 

Pt

 

(point) is the zone and allows you to define 
where the sensor input comes from. 

The board number for the IRLDS II setup is the address 

of the Gateway. If there are three or less IRLDS II control-
lers connected to a Gateway, the Gateway address = the 
IRLDS II address. However, if there are more than three 
IRLDS controllers, the second Gateway address will be the 
one entered for the board number, but the IRLDS II con-
trollers are set 1 to 3 on the second Gateway.

5.

Press 0 (zero) to go back to the 

CONFIGU-

RATION

 screen.

6.

Press 7 for 

I/O Brd Setup

 to reach the 

I/O 

BOARD MENU

 screen.

7.

Press 2 to 

Set Device

 

#’s

.

The Gateway will react as three 16AI boards. The num-

ber of IRLDS II controllers plus the real number of 16AIs 
= the total number of 16AIs to enter in the next step:

8.

At the

 I/O BOARD DEVICE NUMBERS

 

screen, press the down arrow key to reach 

Number 16AI Boards

 and enter the number 

of how many 16AI boards and IRLDS II con-
trollers there are. Press Enter.

9.

Arrow down to the 

I/O BOARD

 

MENU

 and 

press 0 (zero) twice to go back to the 

MAIN 

MENU

 screen.

10. Press 4 for

11. Press 2 for 

Setup

--up to 48 sensor control 

programs are allowed. Select one of the 48 
units and press Enter to reach the
