Bistable/Switch output
Enter the master code each time switches output in the opposite state. This mode is
dedicated to control some device or system which requires bistable (latch) control,
usually it can be used to control arming mode of the alarm zone or entire alarm system.
The Status output can be used for rearming of an alarm zone or to control any other
device or system which requires the ON/OFF method of control
Bell output
Normally this output remains in high resistance state, if triggered it shorts to supply
minus (GND). The Aux output has been designed to indicate two situations:
Door Bell event
Door Alarm event
Whenever the Bell key is pressed for a moment or the [#] key is pressed and held down
longer then half a second, the Aux output goes steady on (shorts to supply minus), the
Aux output remains in this condition as long as the Bell or [#] key is being pressed. The
Aux output can be also activated when Door Alarm is active. The code lock indicates the
Door Alarm through pulsed modulation of the Aux output. Thanks to this feature (steady
or pulsed output) operator may distinguish the Bell signal from the Door Alarm. The
maximum current sink by this output is internally limited to 1.0A, the maximum voltage
applied to it must not exceed 15VDC. Normally the Aux output is used to trigger some
kind of warning device (e.g. alarm siren or buzzer).
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 BELL 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 BELL 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 DR: 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 DC: 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.
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.
