Description

The DSC PG9975 Vanishing Wireless Door/Window Contact offers a discreet way to monitor a door or a window. It is one of the thinnest surface-mount sensors we have seen, and it is nearly invisible once installed. But despite its small size, it boasts all the features of a PowerG Sensor.

What's most striking about the PG9975 is the fact that it is wafer-thin, with a thickness of just 0.3 inches. The complete dimension for the sensor are 2.45"L X 1"W X 0.3"D. But this small size doesn't stop the sensor from offering some impressive features. It will work from up to 2 kilometers away from the panel with a clear line of sight. Also, 128-bit AES encryption prevents the PG9975 from being hacked or taken over wirelessly.

The device works in conjunction with an included magnet. The PG9975 should be installed on the door or window frame, and the magnet should be installed on the door or window itself. For best results, the magnet should be placed within a quarter-inch of the sensor. When the door or window is opened, the magnet will separate from the sensor. This will cause a switch inside the sensor to activate. The sensor will then send an alert to the system to let it know about the open window or door.

The PG9975 can be mounted with either screws or with double-sided foam tape. The device comes included with the double-sided foam tape for easy installation. The device has a battery life of about three years with average use. A user can easily replace the 3V CR2032 lithium battery when it dies. The device will work with any DSC PowerSeries Neo System or any Qolsys IQ Panel 2 System with a PowerG daughtercard.

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.

Outstanding Door/Window Contact!
Submitted on 01/02/2020 Alarm Grid

The DSC PG9975 is a wireless PowerG Door and Window Contact Sensor. It is used with systems that support PowerG wireless technology, including the Qolsys IQ Panel 2 Plus and DSC PowerSeries NEO Panels with added PowerG Transceiver. As a PowerG Sensor, the DSC PG9975 is praised for its excellent wireless range and 128-bit AES encryption.The sensor also features a very thin design that helps it appear almost invisible when mounted on a blank white surface. However, the sensor has been discontinued, and it can no longer be purchased new. Overall, we really like the DSC PG9975, and we give it a 5-Star rating.

There are many things we like about the DSC PG9975. The sensor really shines with its incredible wireless range. It can be used from up to 2 km away from a panel, depending on the type of security system that is being used. The sensor also utilizes 128-bit AES encryption, which makes wireless hacking or takeover attempts virtually impossible. We also like the super thin profile of the sensor, which makes it unobtrusive when mounted. We also like the fact that the sensor is very easy to mount, making it great for DIY users.

There aren't many downsides to the DSC PG9975. The biggest issue is that it is discontinued, and you can no longer buy a new model from Alarm Grid. Its replacement model is called the PG9303. But if you have an existing PG9975 Sensor, then it should still work just fine. Another issue is that since the door and window contact is wireless, you will need to replace the battery every few years. The sensor uses a lithium 3V CR2032 coin battery for this purpose. Overall, the positives for this sensor really outweigh its negatives. We give it 5 Stars.

Good: Great Range, 128-Bit AES Encryption, Super Thin Design, Easy to Install

Bad: Discontinued, Requires Battery Replacements

Bottom Line: 5 Stars
