APPLICATION HINTS FOR THE AUXILIARY TERMINALS
(C) KEY ACTIVE
(a)
(b)
The Key Active Output switches to (-) ground
for 10 seconds whenever a key is touched.
You may use it to turn ON an LED lamp and
/or a small buzzer to notify a guard; or
to energize a relay to switch ON lights or
trigger an CCTV Camera to start recording.
Make sure that the relay for switching ON
lights has high enough isolation between
high voltage and low voltage to prevent
damage of the keypad.
Only one connection option is recommended.
Make sure the sink current does not exceed
the maximum rating of 100mA.
External power supply and isolation relay
are strictly necessary in driving high power
device, such as lights.
(B) DOOR SENS
With the help of a Normally Closed
door position sensor (usually a
magnetic door switch) on the door to
set up the following functions:
Door Auto Relock
-- The system will
immediately relock the door after a valid access
has been gained to prevent "tailgate" entries.
Door Forced-open Alarm
-- The keypad will
generate alarm instantly if the door is forced to
open. Enable the function at Location 80.
Door Propped-up Alarm
-- The keypad will
generate alarm if the door is left open longer
than the pre-set delay time. Enable the function
at Location 81.
Inter-lock Control
-- When the door is open,the
interlock output of the keypad will give a (-)
command to stop the other keypad in an
inter-lock system.

DOOR SENS
(A) TAMPER N.C.
The tamper switch is Normally Closed while the
keypad is secured on gang box. It is open when
the keypad is removed from the gang box. To
prevent sabotage, connect these terminals in
series with a 24 hour N.C. protection zone of an
alarm system if required.
