Description
The KeyPAC Low Profile (PAC Part Number 20441) proximity reader is an accessory commonly
used on a majority of access control systems. The Low Profile uses pre-encoded ISO proximity
cards (PAC Part Number 21030). Each card is encoded with a unique code that outputs a serial
number to the access control system.
The Low Profile is weather resistant and suitable for indoor or outdoor use. Cards are read at a
distance of up to 4 inches.
This reader is also available in off-white by ordering PAC Part Number 20446.
How the Reader is Used
The Low Profile is connected to a reader input on a door controller, time and attendance unit or
control panel, that can except a PAC format, Wiegand 26/ 32/ 64 Bit format or ANSI Magstripe
format. The Low Profile detects and reads the unique embedded coding from each ISO card when
it is presented within 4 inches of the reader. The Low Profile will then output this coding, that has
been received by the card, to the receiving door controller, time and attendance unit or control
panel.
How the Reader Operates
The Low Profile has an LED to indicate reader status. When the reader's LED is red the reader is
ready to read a card and output the coding to the control panel. When a valid card is read the
output will begin sending the information to the control panel. If the card is valid, the control panel
will activate and output to the Low Profile turning the LED to green. This change of the LED will
most commonly indicate a Access Granted condition or an acknowledgment that the control panel
has received and logged the coding from the card.
