Keypad Wiring
To wire a keypad to the alarm controller, remove the keypad backplate (refer to the keypad installation sheet) and connect the RED,
BLK, YEL and GRN terminals to the corresponding terminals on the alarm controller.
Keypad zone/PGM wiring
Hardwired devices can be connected to hardwired keypads with inputs (zone) or outputs (PGM). This saves from running wires back
to the control panel for every device.
To connect a zone device to HS2LCDPRO and HS2TCHPRO(BLK) keypads, run one wire to the P/Z terminal and the other to B. For
powered devices, use red and black to supply power to the device. Run the red wire to the R (positive) terminal and the black wire to
the B (negative) terminal.
