Qolsys QS1231-840
IQ Motion-S Encrypted Motion Sensor
Description
The Qolsys IQ Motion-S is the premier motion sensor for the IQ Panel 2 Plus. This encrypted PIR motion sensor is perfect for any home or small business that need reliable motion detection. The sensor is also backwards compatible with any legacy 319.5 MHz system (Interlogix, GE, Qolsys).
There are many great aspects of the Qolsys IQ Motion-S. The device can be corner-mounted or flat-mounted, and all the necessary mounting hardware comes included. The sensor offers a wireless signal range of 600 feet when used in open air. For best results, the sensor should be used within 100 feet of the panel if possible. You should avoid mounting the sensor near HVAC vents, air ducts, ceiling fans and toward stairwells to prevent false alarms. It should be mounted at 7.5 feet high. The detection range is rated at 30 feet by 40 feet. It offers and 80 degree field of view.
Passive infrared (PIR) motion detection works really well, and it is highly effective in responding to movement. To understand a PIR motion, one should be aware of infrared (IR) energy. Every person and object gives off a small amount of energy. The Qolsys IQ Motion-S detects the change in IR energy that occurs when a person or large object comes into its field of view. The sensor will then alert the panel, and the system will respond based on the programming settings for the zone.
The Qolsys IQ Motion-S uses two (2) AAA batteries for power. It has a battery life of approximately five (5) years. The sensor produces unique transmissions for pairing, tamper, tamper restore, alarm detect motion, alarm restore, RF supervision and low battery. The device dimensions are 3.4"L x 2.4"W x 1.5"D. The motion sensor offers pet immunity for small animals weighing up to 40 pounds. Proper mounting is essential for ensuring effective pet immunity.
The IQ Motion-S offers a Walk Test Mode that is entered whenever the tamper cover is released and then closed. In this mode, the sensor will flash a red LED light whenever motion is detected. This allows the user to perform an effective walk test and check the placement of the sensor. The sensor will exit walk test mode after one (1) minute of no activity.
Note: Qolsys sensors operate at 319.5 MHz. They will not work with the 345 MHz and the 433 MHz versions of the Qolsys IQ Panel 2 Plus. They are designed for the 319.5 MHz IQ Panel 2 Plus and other 319.5 MHz systems.

The Qolsys IQ Motion-S, or QS1231-840, is an outstanding motion sensor to use if you have a 319.5 MHz IQ Panel 2 System. It works great with both the standard version of the Qolsys IQ Panel 2 and the 319.5 MHz version of the newer Qolsys IQ Panel 2 Plus. Since this is an S-Line device, it will use rolling code encryption whenever it is paired with a compatible IQ Panel 2 or IQ Panel 2 Plus System. This makes it a simple, yet secure device that is a great choice for basic residential use. That is why we give it 5 Stars.
One great aspect of the Qolsys QS1231-840 S-Line PIR Motion Sensor is that it offers a very good wireless range. In an open air environment, it can technically communicate from up to 600 feet away from the panel. Qolsys recommends using it from 100 feet or less from the panel if possible, but our technicians have found that most environments will allow the sensor to be used from up to 150 or even 200 feet away. Just make sure you test the sensor if you are trying to use the device further than 100 feet from the panel.
For a PIR motion sensor, the Qolsys QS1231-840 does offer a relatively smaller coverage area when compared with similar devices. Its specified range is just 30 feet by 40 feet when mounted at a height of 7.5 feet. However, the device does indeed detect movement reliably from within this coverage area. And most homes won't really need an interior motion sensor with a super large detection area anyway. With that in mind, you really should have no problem using the QS1231-840 in a residential environment. It even offers pet immunity for small animals weighing up to 40 pounds!
Bottom line, we are impressed with the Qolsys IQ Motion-S, and we think it is a strong all-around residential PIR motion sensor. It gets a 5-Star Rating.
