| |
| === AC power input ===
| |
| All striker relay panels use single phase power. Clappers and hammers operate between 208 and 240 VAC. Swinging bell motor systems come in three phase and single phase versions.
| |
|
| |
| Connect a supply of at least 20A to panels with one to three bells. Add 5A per bell that could ring simultaneously (generally no more than six will ring at the same time). Input terminals L1 and L2 accept up to 10 AWG.
| |
|
| |
| === Hammer and clapper outputs ===
| |
| The striker may be a tolling hammer mounted on the opposite side of the bell from the wheel. These diagrams detail the internal hookup of the relay panel only. Consult the appropriate [[Installation_documentation#Riser_diagrams|riser diagram]] for conduit and power requirements.

| === Swinging motor outputs ===
| |
| Low current relays are used to enable swinging motor systems that use either solid state or electo-mechanical contactors. Multiple relays switch a Common line for multiple bell outputs. The outputs will be labeled M1, M2 (and so on from the largest to smaller bells). These relay outputs connect to
| |
|
| |
| For 2052 swinging bell motors with solid state controls, connect '''M''' to each motor's '''K''' lead (a purple wire). For intelliSwing Precision systems in a separate wall mounted cabinet, connect the Mn output to the Sn switch input. For legacy motors, you need to determine which wire goes to the contactor and reversing switches.
| |
|
| |
| Generally, connect the '''C''' Common terminal (fused at 2A) in the Libertas relay panel to L1 for most cases. If the motor doesn't run, move the jumper to L2 as power leads in existing motors may be reversed. For intelliSwing Precision motor control cabinets, there will either be a '''C''' input near the '''S''' input, or you can use the '''L1-out''' on the logic circuit breaker in the cabinet.

| |
| === Data Cable ===
| |
| A twisted pair data cable is required and typically we use a minimum of CAT5 with RJ45 terminations. The pinout of the terminations and wire colors is the standard B style pin out. The following colors appear top to bottom when cable exits the housing to the left and the clip is away from you:
| |
| [[File:CAT5-Termination.png|400px|thumb|right|CAT5 RJ45 Termination]]
| |
| 1 Orange/White - 12VDC negative
| |
| 2 Orange solid - 12VDC negative
| |
| 3 Green/White - Data A (RS485)
| |
| 4 Blue solid - Status B (RS485)
| |
| 5 Blue/White - Status A (RS485)
| |
| 6 Green solid - Data B (RS485)
| |
| 7 Brown/White - 12VDC positive
| |
| 8 Brown solid - 12VDC positive

| '''Crimping Procedure'''
| |
| # Cut cable to length
| |
| # Strip 1-1/2" of outer jacket from cable without nicking conductors.
| |
| # Pull the jacket back from the end as much as possible.
| |
| # Fan-out conductor pairs, orange top, green, blue brown bottom.
| |
| # Untwist green, arrange green/white above blue, solid green below.
| |
| # Untwist blue, orient solid above blue/white
| |
| # Untwist orange and brown pairs, keep solids below the striped.
| |
| # Flatten the fan and bring together keeping the order shown above.
| |
| # Use scissors to cut the conductors about 3/4" from jacket.
| |
| # Double check wire order and insert conductors fully into the RJ45 connector as shown.
| |
| # Crimp the connector using an RJ45 crimping tool.
| |
| # Inspect the crimp. The wires should be fully inserted and their ends visible at the end of the connector. The gold pins should be recessed in the slots (not protruding above the plastic).
