Post Installation Troubleshooting Wireless Alarms

Sudden problems in RF alarm systems that have already been successfully commissioned are often the result of changes in the environment.

Look for things recently brought into the area like metal framed pictures, metallic insulation or wallpaper, metal shelving, air conditioning, cabling and cars parked under the main roof. If you can’t discover any obvious environmental change, try moving the transmitter – shifting it a few centimetres may be all that’s required. You can turn the unit upside down taking up the same space as before yet moving the antenna a significant distance.

Another option is to insert a non-metallic spacer behind the transmitter. Try swapping sensors in system around and see if there’s any improvement in reporting. A last-ditch solution is to move the receiver, but this should be a final resort. You might be able to get away with moving the receiver just a metre or 2 allowing you to keep the same power and comms links but there’s a chance you’ll have to move the receiver to another location.

The introduction of noise, or passive shielding into an environment can impact on a wireless systems reliability, as well as its range. In some cases, the replacement of a sensor with a long-range device might resolve issues. In external applications, it may be possible to reimagine the system layout in a way that improves performance without compromising detection coverage.
