siren offline

I change the battery frequently and even though the siren never goes off, it says offline within a short time. Why can't these be plugged in or better battery options?

@jamesosuch​ The Extra Siren has an expected battery life of 1 year, depending on its placement and usage. You mention that your siren does not go off, so usage shouldn't be the culprit here; however, interference could be. Depending on the placement of the Extra Siren, the device could be forced to work harder to maintain its connection to the Base Station, which in turn could drain its batteries.

Interference can be caused by dense physical objects literally getting in the way between the Extra Siren and Base Station. If there are thick walls or heavy appliances between the two devices, that could be blocking the signal.

Interference can also be caused by other wireless signals competing for the same airspace. Since the Base Station uses a low frequency to communicate with the components, you'd want to look for simpler devices like remote controlled garage door openers, wireless weather stations, or some types of baby monitors and move them away from the Base Station.

My batteries appear to last about 2 weeks!!

@robhigginson That is very unusual and recommend you call tech support to troubleshoot and, if under warranty, have it replaced.  Under regular usage they should last, in my experience, at least 7-9 months, and I test my system every other month.

@robhigginson this seems like it could be a case of interference. If there are many thick walls or heavy appliances getting in the way between the Siren and Base Station, that can make the Siren to work harder to maintain a connection - forcing its batteries to drain faster. 

We would recommend scanning the area around your siren - are there any large electronics (think WiFi routers, televisions, etc.) or appliances around it? Or any thick walls/doors? If there are, try moving the Siren so there is a path between it and the Base Station that is free of these obstructions.
