October 2023 Archives

Some Resideo 5821 wireless flood and temperature sensors manufactured between July and October of 2023 may not transmit properly. They may fail to learn into the alarm panel or fail to transmit when an alarm occurs. Affected units can be returned to the vendor for refund or replacement.

The 5821 is a versatile wireless sensor from the Resideo (formerly Honeywell) 5800 Series sensor line. Alone, it can monitor for high and low temperature conditions. It can also be used with either a remote temperature probe, or a remote flood-sensing probe. The use of either remote probe allows the 5821 to monitor harsh conditions that the circuitry of the transmitter itself cannot endure.

The date code for the 5821 is located on the box it comes in, and should also be visible as a sticker or a printed series of numbers on the circuit board itself. The date code consists of a 2-digit number for the year and a 2-digit number for the week of that year.

In 2023, between week 30 and week 40*, a manufacturing issue caused 5821 transmitters to be produced with a defect that caused affected units not to transmit properly. These units may never learn into the panel, or they may fail to transmit when a monitored condition occurs. This could result in damage to a home or business.

The date codes included in this notice are 2330 (2023, week 30) through 2340 (2023 week 40). Any unit with date code 2342 or later is not affected by this issue. July 24, 2023 begins week 30, and October 8, 2023 ends week 40.

If you recently purchased a 5821 from Alarm Grid, check the date code on the unit. If it falls within the affected range, contact us at support@alarmgrid.com and we will happily provide you with a warranty replacement. You can read the full notification from Resideo here. If you received a unit that would not learn into the panel initially, it is likely that we have already performed troubleshooting with you and have at least begun the warranty replacement process.

For customers who may not read our blog, Alarm Grid is reaching out to anyone who purchased this product from us from March 2023 until now. We will provide information on the notification, how to check the date code, and will gladly replace any units affected.

*Important Note: When this issue was discovered, production of the 5821 was halted and the issue was investigated to discover the root cause. There was no production of the 5821 during 2023 week 41, which accounts for the seemingly "lost week" missing in the above referenced announcement.

The newest entry in the Qolsys "One Platform" lineup is the Qolsys IQ4 NS. This is basically an IQ4 Hub minus the touchscreen and a microphone. Qolsys is marketing this lineup as a Good, Better, Best offering with the IQ4 NS, IQ4 Hub, and IQ Panel 4 respectively filling each of those roles.

The "NS" in IQ4 NS stands for "No Screen." As a touchless panel, the IQ4 NS does not need to be installed in a visible location. It can be installed tucked away in a closet in the middle of the home or business. By installing in this way, the panel is protected from attack by intruders, and being centrally located it can provide the best range for Z-Wave and other RF devices.

In this world where seemingly everything has a touchscreen, you may be wondering how you control the IQ4 NS. There are a couple of options, actually. First, you can perform any tasks such as arming, disarming, checking status, and controlling automation devices using the Alarm.com mobile app. This app is available in both iOS and Android versions and is available as a free download from the Apple App Store and Google Play Store.

If you're looking for a more traditional security system experience, meaning you'd like to use a keypad, you have options there as well. The IQ Remote is compatible with all panel versions, and the IQ Remote-PG and some of the push-button PowerG keypads are compatible with the IQ4 NS when a PowerG daughter card is installed. Qolsys also plans to roll out a low-cost, battery-powered keypad called the IQ Keypad PowerG at the end of 2023. This is a basic, numerical keypad. It has an estimated three (3) year battery life and up to five (5) keypads can be used per system. It will work with all of the IQ4 panel lineup, as long as the panel supports PowerG.

To program the IQ4 NS locally, the IQ Installer Interface app is used. In addition, dealers can program the panel through the Alarm.com dealer portal. To program at the panel, simply download and install the free IQ Installer Interface app, open it, scan the QR code for the panel, located on the back of the unit, and follow a few onscreen prompts. You'll be programming the panel within minutes. The UI for the installer interface app is very similar to programming the IQ Panel 4 and IQ4 Hub through the panel touchscreen.

Qolsys has made the IQ4 NS a very modular system. Users can purchase a system with only the Z-Wave card installed, for example. This system can then be used as an automation hub only, perhaps in a newly constructed home, for demonstration purposes. When someone buys the home, they may then want to add security sensors. They can purchase a PowerG, 319.5MHz, 345MHz, or 433MHz daughter card to be installed into the panel. Now the same IQ4 NS is a full security system.

Because the IQ4 NS has no screen with which to relay information to the user, it has two (2) LEDs on the front of the panel that provide some information. The left LED indicates power and the right LED indicates security system status.

The table below shows the various LED states and their respective meanings:

Power LED
Solid Green	AC is present.
Flashing Green	System running on battery, AC power is down
LED OFF	System is Powered Down
Status LED
Solid Green	Disarmed, Ready to Arm
Flashing Green	Ready to Arm, with Zones Open
Solid Orange	System Trouble Present
Flashing Orange	RF Jam is Present
Solid Red	System Armed
Flashing Red	An Alarm has Occurred
Flashing Red (Rapidly)	Active Fire Alarm, Bell Silenced
Flashing Blue	Rebooting After an Update
Solid Blue	IQ Installer Pairing Mode

With no touchscreen interface on the panel, the power button also has some additional functionality on the IQ4 NS. See the chart below for details:

Power Button
Press and Hold, 3 Seconds	Panel Powers On, if Currently Off.
Press and Release, While Disarmed	Announces Alarms, Troubles, and any other Status. Alarms and Troubles can be Cleared by Pressing and Releasing again, after Annunciation Ends.
Press Twice within 3-Seconds, While Disarmed	Initiates a Pairing Window for the IQ Installer App. If Enabled in Programming, May Also Initiate a Cell Test.
Press and Hold for 30-Seconds	Initiates a Hard Reboot.

Not all versions of the IQ4 NS are available just yet, but as they roll out, we'll add links to those panels in the chart above. We've been, frankly, unimpressed with prior manufacturers' all-in-one panels with no touchscreen, but the Qolsys IQ4 NS seems to have been well thought out. We'll see how popular it is with our customers.

What do you think about this type of screenless panel? Would you consider purchasing one? Leave a comment below and let us know what you think. It seems that every manufacturer of all-in-one, professional-grade security panels decides to try a screenless panel at some point. It will be interesting to see if Qolsys can succeed where others have failed.
