15 Accelaterm
®
Installation and Service Manual
DOOR CONNECTIONS
Inputs from Card Readers, Keypad/Card Readers and Door
Alarms connect to the Accelaterm via the terminal strips on the
left and right side of the board labeled RDR1 through RDR16.
Wiegand/Proximity Reader Connections
Table 3 below lists the connections between the RDR1 and
RDR16 terminal strips and the Wiegand/Proximity Readers.
* Proximity Readers are normally powered
by +12VDC.
Wiegand/Proximity Reader Cable
Requirements
Wiegand/Proximity Readers require a 5-conductor cable be-
tween the Accelaterm and the particular unit (see Figure 9).
Do not use twisted pair cable.
Note: Readers may have a maximum current draw of 350mA
each.
Table 4 lists the cable gauge-vs.-length requirements for
proper operation
of the Accelaterm and a Wiegand/Proximity
Reader.
CAUTION
Keep all drain and cable shield wires between the
Accelaterm and any Wiegand/Proximity Readers
short. Connect drain and cable shield wires to the
ground posts located on both sides of Accelaterm
cabinet. DO NOT ground drain wires and cable
shields at any other point.
Keypad Connection
Wiegand-Output Card and Keypad Readers -
The preferred connection for “Card and Keypad” installations
is the use of a UL Listed Wiegand – Output Reader/Keypad
such as the HID 5355AGK
00 or 5355ABK00. These products
eliminate the cost of additional wiring, and require no addition
Interface Equipment. Compatible equipment produce the fol-
lowing codes for Keypad entries:
Note: Wiegand-output Keypads may simply be connected to
the Card Reader inputs for “Keypad Only” connections.
