We fit Yale all the time - very good systems.
Batteries last about 2-3 yrs in each device.
"Hello SKY / Crow11",
In general I am happy with my Yale HSA 2500 `Wireless` Alarm System - although as You will read below it is NOT really a `Wireless system` any longer:
But I am only still happy with it because I have been capable of finding out what has caused the various problems that I have had - and been capable of rectifying these myself - it would have been completely different if I was NOT capable of doing the `Fixes`.
I fitted the Yale HSA 2500 Wireless Alarm system in my Home about 13 Years ago to replace an Alarm system on which the Control Box malfunctioned.
Before I purchased the HSA 2500 I contacted the Yale Alarms Technical Department to ask some questions - especially about the possibility of Radio Frequency Interference to the Alarm / Detectors.
I was informed that the `Wireless Alarm used a Frequency that nothing else uses` so there should definitely NOT be any Interference.
I purchased the Yale HSA 2500 Kit and also a few more wireless PIR Detectors - a couple of wireless Door Detectors - the Cable Protector for the Siren Box and some Remote Controls.
When I opened the Box containing the HSA 2500 Kit and saw the Control Box the first thing that I noticed was that there was a Light to warn of Interference !
If there is Definitely NOT any possibility of Interference why is there the Interference warning light ?
I installed the System which at that time required the Siren Box to be wired to the Control Box - but all of the Detectors were wireless.
About a Month after installing the Alarm system the Alarm went off at about 3 AM - there was no Interference Light illuminated at that point but I did find out that the Alarm was caused by a particular PIR Detector which it seems had not communicated with the Control Box with the monitoring signals for I think either 3 or 5 consecutive instances.
This happened again a couple of Days later and during the Evenings I had seen the Interference Light illuminated a few times.
As this was a New System I contacted Yale - sent them the Detector that was instigating the Alarm for a replacement -
but I was concerned about seeing the Interference light a few times.
As I had purchased a couple of Spare PIR Detectors I fitted one where the other PIR had been `malfunctioning` - that same Day the Alarm went off - caused by the New Detector - having not communicated with the Control Box for either 3 or 5 consecutive instances.
After speaking to the Yale Alarm Technical Department We concluded that this was because something was definitely Interfering with the Monitoring Signals from the PIR Detector that was fitted to the Utility Room inside my Home`s Back Door.
There was still the comment / attitude that `We cannot understand this happening` - and that
`Nothing else uses the Frequency that the Alarm uses` - although when I brought it to their attention that there was an Interference warning light on the Control Box and it was mentioned in the Installation Manual that
some Electrical appliances could cause Interference to the Alarm they were lost for a reply.
Something was Interfering with the PIR Detector in that location and I ended up having to Wire it to the Control Box.
Throughout the Years since then there have been similar problems with the Wireless Detectors and I ended up Wiring some more to the Control Box.
Also over the Years I have had to replace the PIR`s - I used Honeywell Wired PIR`s as I rate Honeywell as the absolute Best Manufacturer of Heating Controls - I used the Honeywell Intellisense IS-215T.
Unless I could find out that there was a Technical / Design / RF Frequency reason why there is NOT as much chance of RF Interference with the more recent Models of Wireless Alarm Systems I would definitely NOT install a Wireless Alarm System again in My own Home.
Regarding Battery Life - I used to ensure that I used only Duracell Ultra Batteries since they became available on the wireless PIR`s and wireless Door Detectors and although they probably would last 2 Years or more I made sure that I changed them every Year.
Note on Calendar's to do so as well as the Smoke Alarm Batteries.
Although Wireless Detectors usually go into `Sleep Mode` for a short period each time when people are walking around the Home / Business obviously the more often the Detectors sense movement / `Flash` the more use the Battery gets regarding somewhere that is occupied all Day / all Night.
I have also replaced the Control Box Rechargeable Battery 3 times in the 13 Years.
Regards,
Chris
