External Connections
iGuard
provides easy-access terminals for
connections to external controls,
including Door Strikes, Door Sensor,
Door Open Switch, and External
Alarm.
Door Strike (Optional)
Terminals
#1-3 (1-2 Normal Open, 2-3 Normal
Close). These terminals are
connected directly to the internal
relay, rating at 12V / 5A. If the
door strike is within this current
limit, it can be directly connected
to these terminals. If the system is
used solely for Time Attendance
System, these terminals can be left
open. When using a 12v door strike
a diode is required to be installed
in-line between the iGuard and door
strike to eliminate back EMF.
Door Sensor
(Optional)
Terminals
#4-5. It provides iGuard the current
status of the door (open / close).
If the door is left open for over 10
seconds, iGuard will generate beep
sounds to alert the people.
Door Open Switch (Optional)
Terminals
#6-7. An optional door switch can be
connected to these terminals. It is
used to open the door remotely, such
as opening the door from the inside
of the business premises, or from
the reception area.
External Alarm
(Optional)
Terminals
#8-9. This is used for optional
external alarm. If the case of the
device is forced open during
operation (such as a break-in), an
internal sensor will trigger this
connection, and it will sound the
external alarm.
Power (12V DC)
Terminals
#10 (ground) & #11 (+12V). The power
requirement is 12V DC, 200mA (idle)
800mA (peak). Since most of the door
strikes require the same 12V DC
power supply, iGuard can generally
share the same power supply with the
door strike.
