iGuard IP Appliance for Access Control and Time / Attendance

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.

A typical network diagram showing multiple iGuard Systems connected through a corporate network.  Each iGuard is assigned its own specific IP address.  These systems can be set up in a master / slave configuration so that biometric template data is replicated automatically throughout the network on each iGuard.  Optionally, the template matching can be performed on a secure server at a single point on the network.  For this type of environment, the Client/Server iGuard is necessary.

WAN Network

This diagram shows multiple iGuard units connected through the Internet or over a WAN.  This environment requires the master/slave configuration for template matching because of the latency on the network when retrieving templates and matching them to a central database over the WAN.
