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 HS2LCD E and HS2TCHP E 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.
Keypad zones support Normally Closed Loops, Single End of Line, Double End of Line, and Triple End of Line resistors.
To connect the PGM output, run one wire to the P/Z terminal and the other to R.
