Additional Power Supply
If the current draw for all keypads exceeds the panel output, provide additional current by adding a Model 505-12
auxiliary power supply.
1. Connect all keypad black ground wires to the power supply negative terminal.
2. Run a jumper wire from the power supply negative terminal to the panel common ground terminal.
3. Connect all keypad power (+12 VDC) wires to the power supply positive terminal.
Caution:
Do not connect the power supply positive terminal to any panel terminal. Refer to the
Supply Installation Guide (LT-0453)
Keypad Bus Monitor
For listed fire protective systems, the 893A Module or 277 Trouble Sounder must be installed on the XR150/XR550
Series panel to monitor the keypad bus. It should be programmed to sound when the keypad bus fails to operate.
