Connection between Panel and Keypad/Expansion Board:
The keypad or expansion module’s terminal can be hardwired to the Control Panel.
To do so, connect the keypad or expansion module’s four terminals to the corresponding
terminals on the hybrid panel.
- For KPT-35-COMBO, connect the “V”, “G”, “A”, “B” terminals to the corresponding
“VDD”, “GND”, “485A”, “485B” terminals on the hybrid panel.
- For WEZC-8/WEPC-1/WEZ Series, connect the “VDD”, “GND”, “485A”, “485B”
terminals to the corresponding “VDD”, “GND”, “485A”, “485B” terminals on the hybrid
panel.
Daisy Chain Connection between Keypad/Expansion Board:
You can add more expansion modules/keypads by connecting one to another to form Daisy
Chain Connection.
To do so, connect the keypad/expansion module’s four terminals to the corresponding
terminals on the next keypad/expansion module.
- For connection between keypads, connect the “V”, “G”, “A”, “B terminals to the
corresponding “V”, “G”, “A”, “B” terminals on the next keypad.
- For connection between Expansion Boards, connect the “VDD”, “GND”, “485A”, “485B”
terminals to the corresponding VDD”, “GND”, “485A”, “485B” terminals on the next
Expansion Board.
- For connection between Keypad and Expansion Board, connect the keypad’s “V”, “G”,
“A”, “B” terminals to the corresponding “VDD”, “GND”, “485A”, 485B” terminals on the
next Expansion Board.
Wiring Guideline
The total length of wiring shall not exceed 1000 feet.
A maximum of 128 keypads/expansion boards (including WEZC-8,
WEZ-12/24/36/48-RS485, WEPC-1, KPT-35-COMBO) can be connected to the panel.
Out of the 128 keypads/expansion boards mentioned above, a maximum of 4
KPT-35-COMBO can be connected to the panel.
Wiring Example
KPT-35-COMBO-A is wired correctly as it is within 500’ / 152m of the panel, in wire
distance.
WEZC-8 (A) is wired correctly as it is within 800’ / 244m of the panel, in wire distance.
Since it has the furthest distance from the Control Panel, ensure its jumper switch is set to
ON to serve as a terminating resistor before tightening the cover fixing screw.
WEZC-8 (B) is NOT wired correctly as it is farther than 1300’ / 396m from the panel, which
makes it exceed the total length of wiring of 1000 feet.
Ensure the furthest keypad or expansion module’s Jumper Switch and Control Panel’s J53
Jumper Switch are set to ON to serve as a terminating resistor.
