MICROgarde controller I and II
04.20.11.18
Connections
CAUTION! Please read this section carefully as incorrect wiring could cause irreparable
damage to the controller and invalidate the warranty. Check all wiring before connecting
power to the unit.
2.4.1
Connecting Readers
The MICROgarde controller can be connected to any make or type of reader using the
following communication protocols:
Clock&Data (Magnetic)
Wiegand:
Standard 26 bit
HID 37 bit
Generic Wiegand variable up to 64 Bits
Note.
TDSi readers such as the eXprox, eXprox VR, and TDSi MIfare have colour-coded wires
that match the MICROgarde connections overlay label.
To use 2 readers on each channel for In and Out readers on the same door, then you must
be using one of the following readers: EXprox, EXprox VR, Optica, Optica VR, Digital IR,
EXprox 2, EXprox 2K, EXsmart 2 or EXsmart 2K.
For readers 3 and 4 using EXprox and Digital IR, fit the extra brown wire to CLOCK, for
other TDSi readers please refer to its manual.
CAUTION! Use shielded cable for all readers.
2.4.2
Egress or Exit button
Note.
If you have connected readers on both sides of a single door this option may not be
necessary.
Use switches with voltage-free contacts: a simple short triggers the egress function.
2.4.3
Door sensor
Use a door sensor if you want to know when the door is opened normally, forced open, or
left open too long. MICROgarde can be programmed to associate either an open or closed
circuit with the open/closed door position.
Use sensors with voltage-free contacts as a simple short triggers the function.
