Why is my 5800 series sensor losing RF supervision?
An RF supervision loss occurs when a Honeywell wireless receiver does not receive an RF check-in signal from one or more of its Honeywell 5800 Series wireless devices for a specified period of time. A Honeywell 5800 Series Sensor will send this signal to the receiver every 70 to 90 minutes.
For most Honeywell panels, if the system does not receive a check-in signal from a supervised wireless device for a 12 hour period, it will generate an RF Supervision message. This check signal is typically designated by a 'Check nn' condition, where 'nn' is the (2) digit zone number of the wireless device experiencing the loss of supervision. This will let you know which Honeywell 5800 Series wireless devices are not being seen by your security system.
If the RF supervision trouble shows up after a low battery signal, the wireless sensor may have stopped transmitting after its battery fully drained. A low battery indication usually comes up about one month before the battery dies completely. Replacing the battery within the Honeywell 5800 Series wireless device, then performing two disarm commands should clear the trouble display.
The more common reason for a loss of RF supervision is an environmental factor that is preventing the wireless signal from the transmitter from reaching the Honeywell wireless receiver. Any large metal object located between the wireless receiver and the wireless sensor will oftentimes cause an RF supervision loss. Avoid installing Honeywell 5800 wireless devices on metal doors or windows. As it is often hard to know what materials are within your home's walls, testing your wireless devices before permanently mounting them is recommended. The Go-No-Go test is designed specifically for this purpose. When an issue arises, moving a Honeywell 5800 Series wireless device a few inches up or down, left or right can make a huge difference when troubleshooting an RF supervision loss.
If you are experiencing frequent RF supervision problems, you can try adding a Honeywell 5800RP wireless repeater between your wireless receiver and the devices causing the RF supervision issues. The 5800RP repeater boosts the wireless signal and extends the wireless range of your Honeywell wireless security system.
