Power supply

The Gallagher T15 Reader is designed to operate over a supply voltage of 13.6 Vdc measured

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

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

performance of the reader may be affected by a low quality, noisy power supply.

2.3

Cabling

The Gallagher T15 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.

HBUS cabling topology

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

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

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 multiple HBUS devices to

be individually wired to the one physical location.

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 termination jumpers

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

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

permanently terminated at the module).
