1. Introduction
Proximity Tags
A proximity tag is a small plastic token with a low powered radio transmitter
inside. Each tag contains a unique identity code. (There are 4,294,967,296
32
(2
) different tag identity codes.) Inside the keypad is a sensor. When you
present the tag within about 10mm of the front of the keypad, the control
unit senses the presence of the tag and reads its identity code.
If a user presents a tag that the control unit recognises then the control unit
allows the user to access the system in the same way as if they had keyed
in a recognised access code.
Please note: the KEY-K01 keypad does not have a proximity tag sensor.
You cannot use proximity tags with this keypad. Ask your installer what
type of keypad is installed in your system.
Code Lockout
If a user has problems remembering their code, or has acquired an
unrecognised tag, they may try keying in their code or presenting the tag
several times. If this happens four times in a row then the control unit locks
all keypads for 90 seconds and starts a tamper alarm. Once the 90
seconds is finished then the keypads will allow users to try once again. If
the user gets it wrong again then the keypad will lock them out for a further
90s. Note that the system will log the fact that someone has locked the
keypads in this way by recording "Excess keys tamper".
If your alarm system is connected to an alarm receiving centre then the
control unit will send a signal to the centre as a result of the tamper alarm.
Remote Controls
A remote control is a transmitter that you can attach to a key ring. The
remote control has four buttons and a small LED that glows when it
transmits a signal.
Note that to prevent accidental operation the user must hold a button down
for at least two seconds to ensure a transmission.
When delivered from the factory three of the buttons are dedicated to
setting or unsetting the system (see Figure 3).
