The DSC FSA-410 4-Wire Photoelectric Smoke Detector is designed to monitor a home or a business for fires. Once the device has detected an adequate level of smoke, it will activate and send an alert to the alarm system. The alarm system will then respond based on its programming settings.

Automatic drift compensation allows the FSA-410 to operate properly even if dust has accumulated. If the device reaches its compensation limit, then a trouble condition will occur on the system. The user will then know to clean the device. Cleaning the sensor is very easy, as the device features an removable smoke chamber that can be accessed at any time.

A test button allows users to easily test the device for proper function on a regular basis. The included mounting bracket makes it easy for an end user to install the device. We recommend installing at least one of these devices on each floor of the property in order to achieve proper coverage.

The DSC FSA-410 is a 4-wire smoke detector that works with nearly any system that supports 4-wire smoke detects. As is the case with nearly any 4-wire smoke detector, you will need a relay and some other equipment to use the DSC FSA-410. The product has been discontinued, so you will be unlikely to find a new model anywhere. But should you come across a used model somewhere, it should work just fine. We think the DSC FS-410 is a great product, and we reward it graciously with a 5 Star rating.

There are many positive things we can say about the DSC FSA-410 Smoke Detector. It works with nearly any system that supports 4-wire smoke detectors. You have many options in choosing a zone for the device, as 4-wire smoke detectors can really be used at any hardwired zone, provided that they are configured properly. There is a test button on the DSC FSA-410, which allows you to easily test the device. It also alerts the system and triggers a trouble condition if too much dust gathers in the device. What an exciting feature! And we appreciate the fact that the removable smoke chamber is easily accessed.

But be forewarned, as there are some downsides to the DSC FSA-410 that you should take into consideration. As we mentioned earlier, you will need all sorts of different equipment to properly configure a 4-wire smoke detector with your system. That is why many users will just use 2-wire smoke detectors at an appropriate zone. There is also the fact that you will need to physically install the sensor in order for it to work. But these downsides are minor, and they do not stop us from giving the DSC FSA-410 a 5 Star score.

Good: Versatile, Works at Any Wired Zone, Test Button, Dust Trouble alert, Removable Smoke Chamber

Bad: 4-Wire Smokes Requires Added Equipment, Must be Physically Installed

Bottom Line: 5 Stars
