Door Alarm
The Door Alarm will occur when:
door has been opened without entering of a valid USER code
door has been opened without pressing of the Exit Button
door has not been closed within designated time defined by the C5C6 configuration
settings
Once started the Door Alarm is indicated by the pulsed signal on OUT2 output which is
accompanied by a the continues acoustic sound generated by the internal buzzer.
Pressing any key will cease the acoustic signal – however this does not cancel the alarm
indication on the OUT2 output. The alarm indication on this output disappears when door
becomes closed or automatically after 60 seconds from the moment when alarm arose.
Inputs
Input IN1: Exit Button
Triggering of this input activates Door Lock (momentary) output on the same rules as
entry of the valid USER code. The Exit Button is a NO type input – it becomes triggered
when shorted to supply minus (GND).
Input IN2: Door Contact
This input is dedicated for the connection of a door open sensor. When input is open or
left unconnected the code lock assumes that door is closed, when input is shorted to
supply minus (GND) the SL2000 assumes that door is open.
Input SYS: LED SYSTEM
This input is dedicated to control the LED SYSTEM (yellow), shorting this input with
supply minus lights up LED SYSTEM. The LED SYSTEM can be use to any arbitrary
selected purpose required by the installer (e.g. to indicate actual status of the alarm
system or any other state).
Special options
Option 1: Timed Lock-Out
If this option is enabled the Sl2000 disables the keypad for 60 seconds after three
attempts of entry of the incorrect code. After this time the SL2000 re-enables the
keypad and is ready to accept new keypad’s entries. The end of 60 seconds lock-out time
is indicated by two series of two beeps (** **).
Option 2: Disable USER Codes When in Armed Mode
If this option is enabled the SL2000 grants access only when it operates in Disarmed
mode. With this option active the access to the controlled door will be totally disabled
unless the SL2000 will be switched to Disarmed mode again. Thanks to this formula the
MASTER user can disable access to the room by switching the unit to the Armed mode
and vice verso, he can re-enable access to the controlled door by switching the lock to
the Disarmed mode. The SL2000 can be switched between Armed and Disarmed modes
via the MASTER code only.
Note: The Door Alarm has higher priority than Door Bell. When two of these events occur
simultaneously SL2000 indicates Door Alarm only because it has higher priority then
Door Bell indication.
Note: If you are not going to use a door open sensor leave the Door Contact input
unconnected. Without a door open sensor the SL2000 will not signal the Door Alarm.
