Introduction
The SL2000E electronic code lock is designed for operation as a indoor/outdoor stand-alone door access control
unit. The device is equipped with one relay output, two transistor outputs and two NO inputs. All codes and
parameters configuring the device’s operation are stored in nonvolatile memory.
Functional Description
Door Relay Output
This output is designed to control a door locking device (e.g. door strike or magnetic lock). Each time the valid
USER code is entered the SL2000 starts counting time delay specified by
C1C2
parameters and after it elapses
the relay output is activated for a time defined by
C3C4
value. The triggering of the
Door Relay
output is
indicated by LED OPEN (green), this LED lights up as long as
Door Relay
output is on.
Status Output
When the SL2000 is in
Armed
mode this output is not active and remains in high resistance condition. When
code lock switches to
Disarmed
mode the Status output shorts to supply minus (GND) and stay in this condition
as long as the SL2000 operates in the
Disarmed
mode. The maximum current sink by this output is internally
limited to 1.0A, the maximum voltage applied to it must not exceed 16V DC. The
Status
output can be used for
rearming of an alarm zone or to control any other device or system which requires
on/off
method of control.
Aux 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 24V DC. Normally the
Aux
output is used to trigger some kind of warning device (e.g. alarm siren or
buzzer).
Exit Button Input
Triggering of this input activates
Door Relay
output on the same rules as the entry of a valid USER code. The
Exit Button
is a NO type – it becomes triggered when shorted to supply minus (GND).
Door Contact Input
This input is dedicated for a 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
C1,C2…C10
parameters which appear in this manual refer to configuration settings programmed to
the SL2000 during
Memory Reset
procedure (see section:
Configuring the SL2000
later in this document).
Note: If the option
Disable Access
in
Armed Mode
is enabled the activation of the
Door Relay
output may occur
only when the unit operates in the
Disarmed mode
.
Note: The arming and disarming of a code lock can be carried out by MASTER code only.
Note: The
Door Alarm
has higher priority then the
Door Bell
event. As a result when two of those events occur
simultaneously only the
Door Alarm
is indicated on the output line.
