TELEPHONE CONNECTIONS
1. If an RJ31X jack has been supplied by the telephone company, it is probably wired correctly and the controller can be
connected by plugging the supplied 8 conductor telephone cable into the RJ31X jack. The other end of the cable is spaded.
The green, red, brown, and gray wires must be connected to the controller at the designated terminals under the section of the
board marked 'PHONE'.
2. If required, install the supplied RJ31X jack as shown in the following diagram. The polarity must be correct for proper
operation of the phone access feature.
3. IT IS IMPERATIVE THAT THE PHONE LINE COMING INTO THE HOUSE BE CONNECTED TO A GROUNDED
SURGE ARRESTOR OUTSIDE THE PREMISES. IT IS THE RESPONSIBILITY OF THE TELEPHONE COMPANY
TO PROVIDE THIS SURGE ARRESTOR.
4. INSPECT THE INCOMING PHONE LINES. THE FIRST THING THAT THEY SHOULD GO TO IS A SMALL BOX
ON THE OUTSIDE OF THE PREMISES. THERE SHOULD BE A HEAVY GROUND WIRE COMING FROM THIS
BOX GOING TO A COLD WATER PIPE OR A SEPARATE GROUNDING ROD.
5. IF THERE IS NO SURGE ARRESTOR OR IF THE GROUND WIRE IS MISSING, HAVE THE CUSTOMER INSIST
THAT THE TELEPHONE COMPANY INSTALL ONE FOR THE SAFETY OF THE CUSTOMER.
6. WHEN WIRING A RJ31X JACK, MAKE SURE THAT THE INCOMING PHONE LINES GO TO THE TELEPHONE
COMPANY SURGE ARRESTOR BEFORE THEY GO TO THE RJ31X JACK.
7. When the RJ31X is installed as shown, locate the green, red, brown, and gray spaded wires from the 8 conductor phone cable
and connect to the section on the Omni II controller marked 'PHONE'. Plug the modular end of the cable into the RJ31X
jack. If necessary, bend the tab up on the plug to ensure a tight fit that will not fall out.
8. Verify the following if you have trouble during check out: With the system running, the RJ31X jack properly connected and
all phones on-hook (hung up), the PHONE LED, located in the upper left corner of the controller, should be OFF. If it is on,
reverse the RED and GREEN wires to both the house phones and the telephone company wires at the RJ31X jack. When the
receiver is picked up on any phone, the PHONE LED will come on. When the phone line rings, the PHONE LED will light.
9. If the Omni II is accessed on an in house telephone, the Omni II will disconnect the phones from the phone company lines
and supply its own talk voltage to the phones. The PHONE LED will be on in this case.
10. Refer to FIGURE 5 (RJ31X JACK CONNECTIONS) for this configuration.
