When should you have a normal wired alarm system and when should you have a wireless system?
Wireless systems have matured in the past few years. At one time they were clumsy and prone to continuous false trippings.
The communication between the sensors and the main alarm panel has been improved tremendously. Every sensor is now
supervised which is a technical term that means that the messages are checked and screened and the alarm panel effectively
'talks' to each sensor.
Having said that, the ideal is still a traditional wired system.
Wired systems such as the Visonic Powermax are recommended where installing wiring would be impractible.
Other situation where a wireless system would be installed would be when the system needs to easily removable for example
in student flats or small stores on a short lease.
Wireless sensors are much more expensive than wired units and their batteries need replacing every year or two. they
are also less reliable than wired units and because of power limitations, not all types of sensor are available. eg
external anti-masking sensors or fire-sensors are not manufactured. Wireless smoke detectors, however, are available.
