Egress and Lock Control
The ngerprint reader includes an egress input and a
lock output which can be used to simplify the wiring
when the reader is being used for door or access control.
The lock output consists of a protected open collector
transistor that can be used to operate a relay to control
the door lock. The output will go from open to low for
xed 5 seconds whenever the associated door is trig-
gered.
The on board lock output will operate for a xed
time period of 5 seconds when triggered. If a dif-
ferent time is required then you should use another
output on the system to operate the door lock.
The lock output, and LAN+ power supply are not de-
signed to operate and power the door lock directly. You
should always t a relay and protection diode to the lock
output in combination with a separate power supply.
The optional CM444 Relay Module has been designed
to suit this task. If you require the door to operate when
the mains power has failed then you will also need to t
a battery backup to the external power supply. See the
wiring diagram in Figure 5: for more details.
The Egress input on the readers allow you to simplify the
wiring required to implement a egress button on the
inside of the door. The egress input triggers the lock
output on the reader by operating or ring the associ-
ated Door.
The egress input should be connected via a momentary
or push button switch to system ground. When the but-
ton is pressed the lock output on the reader will trigger
for a xed 5 second period.
For greater security, if the egress input is not being
used it should be disabled via panel programming. See
Devices-Keypads & Readers-General Options in panel
programming.
Any zone on the system can be congured to trigger
a door and can therefore also be used to operate
the lock output on the reader.
Tamper Switch Operation
The ngerprint reader includes a built-in tamper switch
which will trigger when the cover is removed or the unit
is removed from the wall. You should adjust the angle of
the switch leaver to suit the wall surface. If the tamper
alarm is not required it can be disabled via panel pro-
gramming.
Alert Tones
The reader emits several distinct tones to alert you
of particular system events. The volume level can be
adjusted or turned o via programming by setting the
reader volume to the lowest level. See the Devices-
Keypads & Readers-Commands menu in panel program-
ming.
Reader Alert Tones
Event Alert Tone Emitted
Fire
Alarm
If the system registers a re alarm, the
reader will sound 3 short beeps fol-
lowed by a 1.5 second pause. This will
repeat until reset by the user or until
the siren run time expires.
Burglary
Alarm
If the system registers a burglary
alarm, the reader will sound a continu-
ous siren tone until reset by a user or
until the siren run time expires.
Trouble
If a system trouble condition occurs,
the reader will sound 4 x fast short
beeps followed by a 5 second pause
and will repeat this tone until the user
acknowledges the trouble condition
from a display keypad
Exit
Delay
The exit delay warning will sound 1
short beep every second when the
area the reader has been assigned to
is armed. During the last 10 seconds
of exit time the warning tone will
speed up indicating that the time has
nearly expired.
Entry
Delay
The hi/lo entry delay warning tone will
sound once every second when an
entry delay zone in the area the reader
has been assigned to is triggered. If
the system is not disarmed before the
entry time expires then an alarm will
occur.
Error
If an invalid nger is presented to the
reader the unit will sound a 2 second
warning tone indicating that the cre-
dential was rejected for some reason.
See the panel log for more details.
Chime
Alert
If chime mode is active then the read-
er will sound fast short beeps to alert
the user when a zone programmed for
chime is opened. Chime mode is only
applicable when the area is disarmed.
Table 5: Reader Tones
In some situations, you may prefer that the alert
tones are disabled. See the Devices-Keypads &
Readers-Indicator Options menu in panel program-
ming to disable these features. Setting the reader
volume to o will stop all audible warning signals
at the reader.
