Wireless house alarm systems

A wireless alarm system is one where all the main components (hand remote controllers, sensors, keypads and sirens) report to the master panel using a specific radio frequency (therefore, no wiring). Each component runs on its own battery power supply.

Why choose a wireless house alarm system?

  1. Your property has little or no roof cavity or under floor space, so any cabling would need to be surface run to the alarm sensors. This would be visible so not great from an appearance or security point of view.
  2. Portability. A wireless alarm is easier to relocate to another location, so suits people renting or who move houses often.
  3. There are a number of wireless alarm models from a range of brands. Starting with basic DIY models (not available from Garrison Alarms or recommended as they result in false alarms due to low quality components and not insurance approved) to high quality, professionally installed, insurance approved models. The better the quality the more reliable and user friendly they become.
  4. Cost. The wireless alarms offered by licensed registered alarm installation companies who are fully compliant with NZSA requirements will cost more for components compared to hard wired but there is a savings in labour for the installation which means it will finish up being a similar price.

Wireless alarm FAQs

There was a time when this use to happen. Someone using a powerful truck RT (radio transmitter) or a neighbour opening their garage door via a hand remote could set your wireless alarm off. The government recognised there was a need to allocate product groups their own exclusive radio frequency bands. This combined with rolling encryption means the alarm frequency band is now very secure and very difficult to interfere with or corrupt.

Yes but just bear in mind that wireless devices run on battery so manufacturers design wireless components to conserve power where ever possible. The wireless sensors we use are designed to be immediately responsive, just like the wired in ones where the little light momentarily flashes to show you have been spotted. Once a wireless detector flashes it will go into “sleep mode” and then ignore you moving around in the room for a few minutes to conserve battery power. If the little light flashed with every movement batteries would only last a few months.

This has improved markedly in recent years. While the main back up battery in the master panel has a 4+ year life, the batteries in wireless components should be replaced every 2 years as a guide. It is now quite an easy exercise you can do yourself.  The alarm will tell you well in advance with a beeping sound when a battery is beginning to tire.
