Each alarm system typically consists of external bell box, which sounds on activation of alarm, internal siren, which sounds on activation of alarm and a control panel, which comes with back up battery. The alarm is operated by a user friendly keypad with a personal attack facility, which is normally situated near main entry/exit point i.e. front door. Additional keypads can be fitted if required - upstairs in a house for night time arming of system or in a different offices within a factory for example.
Then, depending on the level of security required, passive infra-red wide beams or sensors, or, more typically, a combination of both will be installed. Contacts will usually be fitted on all external doors as additional protection.
