Installing Qt Emitters

Important Considerations: 

• Each run has a maximum of 60 emitters!

• Each run supports a maximum cable length of 1000 ft.

• Each home run cable attached to the control module should be  

        labeled by Zone # and Run #. Adding a logical name (e.g.          

        Marketing, Private Offices) is suggested. In addition, fill out   

        "Zone Destination Record" at the end of this Guide.

• The module has two identical outputs, Run 1 and Run 2. All 

        emitters on Run 1 and Run 2 are controlled equally.

• Each job-made cable should be manufactured according to 

ANSI/TIA/EIA Standard 568-B. See custom cabling guidelines 

on page 9.

• Job-made cables should be tested with a LAN cable tester 

before installation.

Emitter Installation Order

1. 

Set the masking output level 

to the maximum level of 30.

2. 

Refer to the emitter layout 

and wiring diagram provided 

by the dealer for cable run 

connections.

3. 

Run home run cables from 

control module to the location 

of the first emitter for all runs.

4. 

Gather all ceiling tiles (per 

layout drawing) that are to 

receive emitters. Use the 

supplied hole saw to cut holes 

in designated tiles. Cut all 

tiles from the front. (Different 

types of emitter housings are 

available to attach in areas 

where there are no suspended 

ceiling tiles.)

5. 

Push the emitter through the 

front of the hole in tile and 

secure it by pushing down 

and twisting the locking ring 

at the back of the emitter.

NOTE:

1. 

The “tombstone” hook on 

the back of each emitter 

is next to the INPUT jack. 

This can help you find the 

INPUT jack by touch.

2. 

To adjust for unexpected 

obstacles such as 

sprinkler heads, each 

emitter may be moved 

up to two feet (one tile or 

0.6 m) in any direction, if 

necessary.
