The DSC PG9924 Wireless Curtain Motion Detector is ideal for monitoring an entryway or a particular section of a room. Curtain motion detectors differ from standard motion detectors in that they do not look for motion throughout an entire room. It will work with any PowerG-compatible panel.
A curtain motion detector does not pickup motion throughout an entire room. Instead, this type of sensor sends out a relatively thin detection signal, and it can only detect motion when someone moves directly in front of it. As stated before, the PG9924 works best when monitoring an entry way or to see if someone moves into a particular section of a room. The detection signal it sends out is thin, and its length can be adjusted using based on the situation.
The device can be set up to utilize coverage lengths of 6, 12 and 18 feet depending upon the size of the opening it needs to monitor. Setting it to a lower range can be useful for reducing false alarms on the system. But the option is still there to increase the coverage area at any time if needed. This gives the PG9924 excellent versatility as a motion detecting sensor.
The PG9924 is a PowerG Sensor. This means that it will work with any DSC PowerSeries Neo Panel and any Qolsys IQ Panel 2 Plus that has a PowerG daughtercard installed. The device has a maximum communication range of up to 2 km away from the panel in open air. As a result, it can be reliably used across an entire property, such as in a barn or a detached garage. The wireless sensor utilizes 128-bit AES encryption to prevent it from being taken over in a wireless attack. It has a battery life of about 7 years using a CR123A lithium battery.
NOTE: The maximum range for a PowerG Sensor when used with an IQ Panel 2 Plus System is only 2,000 feet in open air. This is considerably less than the advertised 2km range. The 2km range refers to when a PowerG Sensor is used with a DSC PowerSeries NEO System.
