The DSC PT4 Proximity Tag is a special device that will automatically disarm a DSC Impassa or PowerSeries Panel. It can only be used if a WT5500P External Keypad is programmed. The PT4 can be held up to the WT5500P to perform an action that would otherwise require a code. Buy the PT4 here.

The DSC PT4 is a proximity tag that works exclusively with DSC Systems. The device can only be used if there is a WT5500P Keypad programmed with the system. When the PT4 is held up next to the tag reader on the WT5500P, it will provide the same function as entering in a valid user code.

The PT4 is a great product for users who might have a hard time remembering system codes. It can also be temporarily given to a guest so that they can arm and disarm the system without actually knowing a regular system code. The device has a diameter of just 1.35 inches, making it very convenient to carry around in a pocket or a purse.

To use the PT4, simply hold the device up against the tag reader on the WT5500P Keypad when a valid code needs to be entered. The keypad will recognize the device, and it will simulate providing a user code. The battery in the PT4 will need to be replaced roughly every 8 years in order to keep it working.

Please note that the PT4 will only work with the WT5500P Proximity Keypad. It will not work with the standard WT5500 Keypad!

Update: the PT4 will also work with the WTK5504P Touchscreen Keypad for the DSC Impassa. This keypad also includes a proximity tag reader. But it will not work with the standard WTK5504 Touchscreen Keypad, as it does not include a proximity tag reader.

The DSC PT4 is a replacement proximity tag for use with the DSC WT5500P Keypad. This is an optional keypad for a DSC Impassa System that includes a built-in proximity tag reader. The DSC PT4 also works with the DSC WTK5504P Touchscreen Keypad, which is also built for use with the DSC Impassa Security System. While both of these keypads already come with a proximity tag, you may need to replace it with a new one. Or another possibility is that you just want a second proximity tag for the keypad. Either way, the DSC PT4 works great in this role. For that reason, we give the DSC PT4 a 5 Star rating.

There are many reasons to like the DSC PT4 Proximity Tag. For one, it offers a convenient way to arm or disarm the system, in place of entering a valid code. It is great for users who may suffer from memory loss, as well as those who do not feel like entering a code. The DSC PT4 is small and compact, and you can easily store it inside your pocket, purse, or even inside your wallet. The device is very easy to use, as you can just hold it up to the proximity tag reader after it has been properly programmed.

There are some downsides to the DSC PT4 Proximity Tag that should be kept in mind. For, it only with compatible DSC Keypads that include a proximity tag reader. This restricts its use. The proximity tag has a built-in battery that must be replaced roughly every eight (8) years in order to continue working properly. The proximity tag should be treated as a user code, and losing it would be a security risk. Also consider that the DSC PT4 will take up a user code slot on the system. But these downsides are relatively minor, and they do not stop us from awarding the DSC PT4 a 5 Star score.

Good: Convenient, Small & Compact, Easy to Use

Bad: Limited Compatibility, Battery Requires Replacing, Losing PT4 is Security Risk, Requires Own User Code

Bottom Line: 5 Stars
