Figure 4. Two-Way Key Fob Buttons
Operating the buttons
To ensure that the fob does not accidentally operate while it is in
your pocket, the buttons are deliberately slow to respond to
pressure. You must hold down the button you intend to press for
at least three seconds to activate its function.
Once the fob recognises that you intend to press a button, a red
LED next to the button will flash three times quickly. At the same
time the fob sends a radio message to the control unit of your
alarm system.
After carrying out the function you selected on the fob, the control
unit will send back a signal to the fob. The fob lights a green LED
next to the appropriate button for three seconds. The green LED
is your confirmation that the control unit has carried out the
function indicated by the button.
Radio Hold Up Alarms (HUA)
A radio HUA is a two button transmitter, used to start a Hold Up
Alarm (originally known as “PA”: Panic Alarm or Personal Attack).
To activate the transmitter you must press both buttons at the
same time. On some models a third button acts as a lock so that
you can prevent the HUA accidentally operating when carrying it
in your pocket (see Figure 5).
