External Paging Relay Control
An announcement broadcast into a Paging zone can additionally activate the system relay in the CPU PCB.
The following products should help if you make your own cables. The connector is generally referred to as a
RJ45 connector wired in an RJ61X configuration. Check with your local supplier for comparable products.
● Suttle SE-266-8K 8 Position Modular Plug (requires an SE-166 or SE-166-6 modular crimping tool).
● Hubbell BRFT4P Snap-On 8 Position Modular Plug (does not require a special crimping tool).
Connecting the Relay for External Paging Control
To Connect the CPU Relay for External Paging Control (Figure 4-2)
1. Find an available connector in a station cable and make sure it is correctly punched down at the
66M1-50 block.
Follow standard color code order. Be sure the block is properly cross-connected.
2. For the connector chosen, locate pins 3T and 3R and connect the device the relays will control.
3. Plug the modular jack into the CPU modular connector.
Programming the Relay for External Paging Control
● In 0201 - CPRU Relay, to assign the CPU Relay for External Paging control, enter 2.
● In 0201 - CPRU Relay Page Zone Assignment, enter the Page Zone (1-7) that should activate the CPU
relay. Note that Zone 1 and All Call Paging announcements broadcast from the External Paging output.
