3.1.5 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, HS2ICON, HS2LED and HS2TCHP 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) ter-
minal and the black wire to the B (negative) terminal.
Keypad zones support Normally Closed Loops, Single End of Line and Double End of Line.
To connect the PGM output, run one wire to the P/Z terminal and the other to R.
Figure 3-5 Keypad P/Z Terminals
Note: When using end of line supervision, connect the zone according to one of the configurations outlined in "Zone Wiring"
on page 21. End of line resistors must be placed on the device end of the loop, not at the keypad.
Assigning Keypad Zones
When using keypad zone inputs, each input used must be assigned a zone number in Installer Programming.
First, ensure that you have enrolled all installed keypads into the desired slots (See "[902] Add/Remove Modules" on page
133). Next, assign keypad zones by entering programming section [861]-[876], subsection 011 for keypads 1-16. Enter a 3-
digit zone number for each of the keypad zones. This number must be programmed into the slot location that the keypad is
assigned to.
Note: If a keypad zone input is assigned to zone number 1 to 8, the corresponding zone cannot be used on the main control
panel.
Once the keypad zones are assigned, you must also program zone definitions and zone attributes. See "[001] Zone Types"
on page 70 and See "Zone Setup" on page 70.
