APPLICATION HINTS FOR THE AUXILIARY TERMINALS
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.
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.
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.
