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 (+12VDC) wires to the power supply positive terminal.
Do not connect the power supply positive terminal to any panel terminal. Refer to
the 505-12 Power Supply Installation Guide if needed (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.
