Power supply

The Gallagher T12 Reader is designed to operate at a supply voltage of 13.6Vdc measured at the

reader terminals. The opera ng current draw is dependant on the supply voltage at the reader.

For a MIFARE reader, at 13.6 Vdc the current draw is 50 mA (idle). During creden al read, beeper

and LED ac vity, the current will momentarily reach 77 mA (maximum). For a Mul Tech reader,

at 13.6 Vdc the current draw is 80 mA (idle) and will momentarily reach 142 mA (maximum). The

power source should be linear or a good quality switched-mode power supply. The performance

of the reader may be aﬀ ected by a low quality, noisy power supply.

2.3

Cabling

The Gallagher T12 Reader requires a minimum cable size of 4 core 24 AWG (0.2 mm

security cable. This cable allows the transmission of data (2 wires) and power (2 wires). When

using a single cable to carry both power supply and data, both the power supply voltage drop

and data requirements must be considered. For good engineering design it is recommended that

the voltage at the reader should be approximately 12 Vdc.

HBUS cabling topology

The HBUS communica ons protocol is based on the RS485 standard and allows the reader to

communicate over a distance of up to 500 m (1640 ).

The cabling between HBUS devices should be done in a "daisy chain" topology, (i.e. A "T" or

"Star" topology should not be used between devices). Should "Star" or "Home-Run" wiring be

required, the HBUS 4H/8H Modules and the HBUS Door Module allow mul ple HBUS devices to

be individually wired to the one physical loca on.

The end devices on the HBUS cable should be terminated using 120 ohms resistance. To

terminate the Gallagher Controller 6000, connect the supplied on-board termina on jumpers

to the Controller. To terminate a reader, connect the orange (termina on) wire to the green

(HBUS A) wire. Termina on is already included at the HBUS Module, (i.e. each HBUS port is

permanently terminated at the module).
