After finding an acceptable mounting location (based on testing), mount the DTIM as described.

1. With the cover off, place the DTIM at the desired location and mark the mounting holes (see 

Figure 3 at left).

2. Make holes in the wall for anchors at the marked locations.
3. Insert wall anchors where necessary, then use two #6 screws to secure the DTIM to the wall.

Connect the DTIM ahead (or in front) of all other phones, answering machines, computers, or any 
other devices on the phone line. This allows the DTIM to take over (seize) the phone line, even if 
another device on the line is in use.

An RJ-31X (CA-38A) jack should be installed when wiring for full line seizure. This lets the user 
quickly and easily disconnect the DTIM from the phone line in case the DTIM disables the phone 
line due to a malfunction.

1. Run a 4-conductor cable from the TELCO block to the RJ-31X (A in Figure 4).
2. Connect the 4-conductor cable wires to the RJ-31X (B in Figure 4).
3. Disconnect the Green and Red premises phone jack wires from the TELCO block and splice 

them to the 4-conductor cable Black and White (or Yellow) wires (C in Figure 4). Use weath-
erproof wire connectors for these splices.

4. Connect the 4-conductor cable Green and Red wires to the TELCO block TIP (+) and Red to 

RING (-) posts (D in Figure 4).

5. Insert the 8-conductor phone cord plug into the RJ-31X jack (E in Figure 4).
6. Remove the right knockout on the DTIM plastic, 

feed the 4-conductor phone cord plug through it 
and connect the plug into the DTIM phone jack 
(Figure 5 at right).

After connecting the phone line to the DTIM, conduct 
a phone test to verify reports are made to the central 
monitoring station. The following steps describe the 

basic steps for conducting a phone test. Refer to the 
specific panel installation instructions for complete 
details.

1. Call the central monitoring station to inform them you are testing the system.
2. Make sure the panel has the correct account number and central station receiver phone num-

ber programmed.

3. Enter the appropriate phone test command for the panel used in the system.
4. Contact the central monitoring station when you are finished testing.

After installation, programming, and testing are completed install the Ty-wrap around the battery 
and battery holder. Cut off any access.

Secure the cover with the cover screw by installing it through the cover push tab.
