IGuard Hardware Connections
Hardware Connections
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.
