Wishlist design form - try our new Alarm System Design Page, all the relevant information on one page with suggested equipment.

The articles show typical examples of alarm system designs. Obviously, the designs are only typical and your property is probably entirely different in layout. However the examples do provide a good guide as to what is required for the alarm system. All the examples shown can be expanded to include components such as the following.

• Extra detectors - most Control Panels have 8 available alarm zones, however, this does not mean you are restricted to 8 detectors as more than 1 detector can be connected to a zone. Any type of hard-wired detector can be connected.
• Smoke detectors - these are just another form of powered detector. They are usually wired into a zone set as a Fire zone (operates 24hrs). Multiple detectors can be wired into the same zone.
• Internal sounders - several extra internal sounders can be fitted but bear in mind that the bell output is around 1 Amp, but generally 2 or 3 are OK.
• Extra External sounders - extra external sounders can be fitted but they must be configured in SCB mode (most have the SAB/SCB option - see compare external sounders)
• Speech Diallers - speech or speech & text diallers can be fitted to any system but, in order to use the full facilities of the dialler, a control panel with communicator outputs should be used. Such panels include the ADE Accenta range, the Texecom Veritas R8 Plus and Excel, and the Scantronic 9x5x series to mention a few.
