Qolsys recently released a service bulletin describing an issue with certain IQ Hardwire 16-F units. This issue affects both the small enclosure and large enclosure versions. Under certain circumstances, affected units can signal a false tamper/tamper restore message for connected zones.
Qolsys TSB #210708, which was released on July 8, 2021, describes this issue, and the corrective action Qolsys is taking to remedy the problem. They do not provide a lot of information regarding what "conditions" bring about this behavior. We have asked for more detail, and if more information is forthcoming, we will provide updates here in our blog.
Rest assured that only a certain number of these devices are affected, and we will provide users with the necessary information to determine if they have one of these units. Qolsys IQ Hardwire 16-F units that were manufactured outside of the window in question are not affected and should not exhibit this behavior.
How to determine if your Qolsys IQ Hardwire 16-F small enclosure (SKU: QS7133-840) is affected:
On the unit itself, or on the box that the unit came in, check the Revision Sticker. This will appear as a bar code on the sticker and will be marked with SN: and DL: If the 4th character of the SN, moving from left to right, is a "C" then the Qolsys IQ Hardwire 16-F small enclosure should be returned/replaced. This sticker may be found on the rear of the unit and may require that you dismount the unit from the wall to get access it.
How to determine if your Qolsys IQ Hardwire 16-F large enclosure (SKU: QS7134-840) is affected:
On the Qolsys IQ Hardwire 16-F large enclosure, the way you determine the revision is the same, but the revision information is different. On these units the revision to be on the lookout for is "B" rather than "C". This sticker should also appear on the unit itself as well as on the box that the unit comes in. Since these devices come from the factory with an enclosure, the sticker may be on the enclosure rather than the printed circuit board. Unfortunately, it may also be on the back of the enclosure, requiring that it be removed from the wall to be accessed. When reading the sticker, the 4th character when viewing the SN from left to right is "B" on affected units. See the example below:
Qolsys has pulled back available affected stock to correct this issue. Units that may have been affected, but have since been pulled back into manufacturing and reworked or replaced, will sport a sticker that says "TEST OK".
If you purchase a Qolsys IQ Hardwire 16-F that falls within the Revision range discussed above, but the item has a "TEST OK" sticker affixed somewhere on the packaging or the unit itself, then you do not have to worry about this issue. If you purchased a Qolsys IQ Hardwire 16-F prior to the date that this notice was released, and your device falls within the revision range discussed above, then you should contact your distributor to discuss replacing the unit. Per Qolsys, you should do this even if you haven't observed the behavior described in this Technical Service Bulletin.
