The Care-Call pendant panic button is surrounded by a protective rim and is activated when the panic button is pressed for one second. This has been designed into the system to prevent activation when the pendant is dropped or accidentally pressed, which will minimise false alarm activations.

One of the unique selling points of the Care-Call pendant is that it has three Light Emitting Diodes (LEDs) which inform the user what is going on after the panic button has been pressed. On pressing the panic button for a period of one second all three LEDs, red, orange and green, will illuminate for three seconds along with an audible tone.

The orange and green LEDs will then go off, leaving just the red LED illuminated. On receipt of the alarm signal from the pendant the home unit will start to dial the pre-programmed telephone numbers and inform the user that it is doing so by only the orange LED being illuminated. Once a connection has been made and recipient has pressed the * key on their telephone accepting the alarm call, the Care-Call home unit will then send a signal back to the pendant and now only the green LED will be illuminated, informing the user that they can now speak into the microphone on pendant and listen to the monitoring station or the recipient via the loudspeaker within the pendant.

The Care-Call pendant has a built in battery management system, giving an audible and visual alarm and will automatically transmit a low battery status to the Castle Care-Call home unit where it will be displayed on the home unit display during an alarm condition only. If the Home unit has been programmed to dial an Alarm Receiving Centre, then they will be automatically alerted at the same time.
