Shipment Contents
Check the shipment contains the following items:
• 1 x Gallagher T11 Reader facia assembly
• 1 x Gallagher T11 Reader base
• 1 x M3 Torx Post Security screw
• 2 x 6-32 UNC Phillips drive fixing screws
• 4 x 25 mm No.6 self tapping, pan head, Phillips drive fixing screws
• 4 x 40 mm No.6 self tapping, pan head, Phillips drive fixing screws
Power Supply
The Gallagher T11 Reader is designed to operate over a supply voltage range
of 9 - 16 Vdc measured at the reader terminals. The operang current draw is
dependant on the supply voltage at the reader. For the Mifare reader at 12 Vdc the
current draw is 90 mA (standby). During card read, beeper and LED acvity, the
current will momentarily reach 125 mA (peak). For the MulTech reader at 12 Vdc
the current draw is 90 mA (standby) and will momentarily reach 140 mA (peak).
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.
Cabling
The Gallagher T11 Reader requires a minimum cable size of 4 core 24 AWG
(0.2 mm2) stranded 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. Although the reader is specified to operate at 9 Vdc, for good
engineering design it is recommended that the voltage at the reader should be
approximately 12 Vdc.
