OUTPUT 2 (NPN TRANSISTOR OPEN COLLECTOR)

The Output 2 is an NPN transistor open collector output controlled by User Code 2, and can be used for some auxiliary controls. It is equivalent to an N.O. output rated 100mA @24VDC.

1. Shunting an N.C. Protection Zone

Use output #2 to shunt an N.C. protection zone.

Set output #2 to ON/OFF Mode (See pg.14, section 3, programming option 51).

WIRING – Auxiliary Accessories

1. Tamper N.C.

When the keypad is secured in the single-gang box, the tamper switch is in the closed position. When the keypad is removed, the tamper switch will open. Connect the terminals to a 24-hour N.C. alarm system protection zone if required.

2. Door Sensing

a) Auto Relock – The door will relock after granting access to prevent ―tailgate‖ entries.

		ALARM CONTROL PANEL

Refer to your alarm control panel manual to determine whether the arm- disarm control is NC or NO.

Set output #2 to momentary mode for multi station systems or ON/OFF mode for single-station systems. See page 14, section 3 for programming options.

b) Forced-Open Alarm – Alarm will go off instantly if the door is forced open. Enable this function with programming option 801 (found on pg.14).

c) Door-Propped-Open Alarm – Alarm will go off if the door is left open longer than the programmed delay time. Enable this function with programming option 9 (1~999 seconds).

3. Drive an Optional Output Relay

Use a 12VDC relay and connect it to the same 12V power supply as the keypad.

d) Mantrap (Interlock) Control – When the door is open, the interlock output of the keypad will switch to ground to disable the other keypads.

3. Duress Output

4. Connecting Inhibit Control

WARNING

Make sure nobody is inside the house before starting the door lock inhibit function.

The inhibit authorization code should always be kept by only the owner.

Using this setup, the owner may enter the user code for output #2 to disable output #1 during a certain period to prevent unauthorized access.

Set output #2 to ON/OFF mode

(pg.14, section 3, programming option 51). Connect the O/P 1 INHIB terminal with the

O/P 2 N.O. terminal as shown in wiring diagram. User code #1 is invalid while the O/P 1 INHIB terminal is shunted to ground via user code #22.

Duress

Output

When a duress code is entered, the duress output will switch to (-) ground. It can trigger a connected LED lamp or small buzzer to notify a guard, or connect it to a 24 hour N.O. alarm system protection zone.

NOTE: Only one connection option is recommended. Output current must not exceed 100mA.
