In this case it has been decided that only the ground floor is to be alarmed and only the main living space. The kitchen window is not protected, but any movement further than the kitchen will be detected by the PIR in the lounge/dining room.

Note that if the Lounge and Dining room were separated then either another PIR should be fitted in the dining room or the existing PIR placed in the more vulnerable of the two rooms (normally the rear room).

The magnetic contact at the front door is wired to the entry/exit zone on the control panel.

The magnetic contact at the rear door is wired to zone 2 on the control panel.

The PIR is wired to zone 3 on the control panel.

In operation any of the zones can be separately controlled. For example during the night, just the two magnetic contacts can be used so that for example the family dog can roam the ground floor. During the day or on holidays, then the whole of the alarm can be used.

The parts list for this installation is:

• Control Panel - Stand-alone type; i.e. the keypad is part of the control panel. Honeywell (ADE) Optima G4 compact,Texecom Veritas 8 and 8 compact, Scantronic 9448EUR-90, and MDT Avanti Compact are typical examples. See Compare Stand-alone Control Panels for individual panel features.
• Back-up Battery - For compact panels this will be 2.1Ah, for large cased panels (veritas 8) any battery up to 7.0Ah can be used.
• External Sounder - Any external sounder can be connected. The choice is on style and output - some sounders have two piezo sounders and are thus slightly louder. See Compare External Sounders for individual sounder features.
• 2 x Magnetic contacts - choose flush or surface, terminal or pre-wired.
• 1 x PIR (Passive Infra-red) detector - can be standard, pet friendly or dual technology.
• 1 x 6 core alarm cable - the PIR and external sounder need 6 core cable, the magnetic contact only require 4 cores.
