CONNECT 12 OR 24 VOLTS AC OR DC TO THESE TERMINALS. CONNECT
DC POWER WITH THE (+) AND (-) POLARITY AS INDICATED. AC POWER
DOES NOT REQUIRE POLARITY OBSERVANCE. THE KEYPAD IS AUTO
VOLTAGE SENSING. WHEN USING AC ELECTRIC STRIKE USE AC POWER ONLY.
OUTPUT 1
(RELAY 1)
OUTPUT RELAY 1 HAS S.P.D.T. DRY CONTACTS RATED 5A@ 28 VDC. THIS
RELAY CAN BE PROGRAMMED FOR LATCHING MODE OR MOMENTARY
TIME DELAY MODE FROM 1 TO 999 SECONDS.
OUTPUT 2
(RELAY 2)
THIS IS AN AUXILIARY OUTPUT CONTROLLED BY USER CODE 2.
OUTPUT RELAY 2 HAS S.P.D.T. DRY CONTACTS RATED 1A@ 28 VDC. THIS
RELAY CAN BE PROGRAMMED FOR LATCHING MODE OR MOMENTARY
TIME DELAY MODE FROM 1 TO 999 SECONDS.

A NORMALLY-OPEN REQUEST TO EXIT STATION CONNECTED TO THIS
TERMINAL AND GROUND, (-) WILL OPERATE OUTPUT 1 FOR THE SAME
TIME PERIOD AS THE USER CODE. MULTIPLE REQUEST TO EXIT
STATIONS CAN BE CONNECTED IN PARALLEL TO THESE TERMINALS.

DRY CONTACTS
Dry contacts do not have voltage connected to them. The Relay Output contacts in the KP-400
Keypad are dry contacts.
N/C CONTACT
The contact is closed in the static state and open in the active state. The contact is open when
the circuit is active.
N/O CONTACT
The contact is open in the static state and closed in the active state. The contact is closed when
the circuit is active.
TRANSISTOR OPEN COLLECTOR OUTPUT
An open collector output is equivalent to a normally-open, (N/O), contact referring to ground, (-), the
same as a relay contact connected to ground, (-). The transistor is normally turned Off, and the
output switches to ground, (-), when turned On.
The Duress, Inter-lock and Key Active Outputs are open collector outputs and the current is limited
to 100 Ma. maximum and 24 VDC maximum.
