The basic principle of a ‘Bells only alarm’ is that the burglar alarm makes an audible noise from external or internal siren when the alarm goes off. These kind of alarms generally don’t have any on-going maintenance but have the option of servicing on a ‘pay-as-you-go’ basis. A bell only alarm can be hard wired or wireless but is not capable of generating police response. You can add a Speech Dialler to a bell-only alarm which enables your alarm to call a selection of telephone numbers should the alarm be activated. With this type of alarm system you are generally reliant upon your surrounding neighbourhood to respond if you alarm is activated if you are not present.
