Greatest Costs At this time: X-Sense XS0B-MR Interconnected Good Smoke Alarm
X-Sense’s XS0B-MR31 Interconnected Good Smoke Alarm is a completely interconnected smoke detection system that not solely sounds all its alarms concurrently when any one in all them is triggered, but it surely additionally sends push notifications to your telephone and makes use of native voice bulletins to let you know wherein rooms smoke has been detected.
The package reviewed right here consists of a base station and three satellite tv for pc detectors that you just mount to the ceilings of the rooms you need to monitor (a 6-detector package can also be accessible). In that respect, it’s similar to the X-Sense XS01-M Interconnected Good Smoke Alarm (mannequin FS31) I reviewed earlier in August.
Specs
In truth, each packages use the identical X-Sense SBS50 base station, which is powered through a USB-C cable. The bottom station doesn’t have a battery backup and received’t ship push notifications if it’s not powered.
These X-Sense smoke detectors make voice bulletins informing you as to which room smoke has been detected in.
Since I’ll be evaluating these two equally named merchandise all through this text, I’ll check with them by their mannequin numbers, as an alternative of their full names. X-Sense mannequin FS31 is the system I reviewed earlier, and mannequin MR31 is the mannequin reviewed right here.
The important thing operational distinction between the 2 methods is that the mannequin MR31 makes use of XS0B-MR satellites that characteristic voice alerts along with sirens; so, as an alternative of only a blaring klaxon, every alarm additionally speaks to you, telling you particularly wherein room smoke has been detected.

This package got here with three of X-Sense’s XS0B-MR smoke detectors. The SBS50 base station on the coronary heart of the system can help as much as 50 different X-Sense detectors, together with carbon monoxide, water leak, and different varieties of sensors.

Whereas that’s not a main improve, it definitely doesn’t harm within the occasion of an emergency, particularly when you have a bigger house. It may probably prevent treasured time finding the supply of the emergency, which may very well be doubly essential if the occupant of that room is an toddler or somebody with mobility points who would possibly need assistance getting out.
The MR31 package’s XS0B-MR detectors are significantly bigger with a extra conventional industrial design, with every disc measuring about 4.25 inches in diameter. The look is extra dated than the pint-sized, non-talking XS01-M satellites that include the FS31 package, however they’re at the very least smaller than a standard off-the-rack smoke alarm. I also needs to level out that neither of those sensors will provide you with a warning to the presence of harmful ranges of carbon monoxide.
As I’ve already talked about, three XS0B-MR satellites come on this package, however you may interconnect as much as 24 of them on a single community. Every is powered by a replaceable 3V lithium cell (included) that can function the alarm for five years. The alarms themselves will have to be changed after 10 years of service.
Set up and setup
The setup course of for each alarm methods is equivalent, which implies scouring the X-Sense app for the proper mannequin satellites so as to add. X-Sense suggests you may scan the QR code on the again of your handbook as a shortcut, however—shock—there is no such QR code anyplace on or within the handbook. As a substitute, I needed to sift via the app’s setup display one web page at a time, primarily making an attempt to match the thumbnail photographs to the looks of the XS0B-MR satellites.

You should use the X-Sense app to check every alarm, which is much extra handy than climbing a ladder to push a button.

I ultimately discovered the alarm in query, and it wasn’t beneath the Hyperlink+ Professional Smoke Alarms part however somewhat beneath a separate one, Hyperlink+ Professional Smoke Alarms with Voice Alerts. The underside line is that X-Sense now has too many merchandise for this sort of setup to be environment friendly, and it’s time for it to improve to a extra automated Bluetooth-based or QR code-oriented onboarding system.
Oddly, establishing the SBS50 base station does contain scanning a QR code on its underside, making for a far cleaner technique to get the system speaking along with your 2.4GHz Wi-Fi community (5GHz networks aren’t supported). As with the FS31 system, the bottom station is the one machine that communicates straight with Wi-Fi and the X-Sense app. The satellites talk with each other over a proprietary 915MHz frequency band and have very lengthy vary: 500 meters, line of sight (partitions in between the satellites and between the satellites and the bottom station will in fact scale back that vary significantly).
Efficiency
As with X-Sense’s FS31 system, the MR31’s alarms will talk with one another whether or not or not its base station is on-line. I examined the alarm extensively with each the app’s alarm-test characteristic and with artificial smoke, and I discovered all options labored as marketed. Simply as with the FS31 system, even after I separated the satellites so far as I may round my home, all of them instantly sounded off with ear-piercing sirens when anybody unit was triggered—the one distinction was the added supply of voice warnings that instructed me which room’s alarm had been triggered initially.
And far as I skilled with the FS31 system, the interconnectivity labored simply as properly even when the bottom station was unplugged. The one distinction is that I didn’t obtain any push alerts on my telephone, and I couldn’t use the app to silence the alarms. Once more, the bottom station may actually use a easy battery backup system to mitigate this flaw. I might encourage consumers to put money into a small uninterruptible energy provide to plug it into.
The MR31’s configuration choices are equivalent to these of the FS31: You alter the amount of the bottom station’s alarm (however not the satellites) and select between three completely different siren sounds for every satellite tv for pc. Notifications can be configured individually for every alarm, primarily based on when the alarm is triggered, ends, silenced, examined, malfunctions, or its battery runs low.
Notifications had been invariably efficiently despatched through each push notification and e-mail. I by no means encountered any hassle with the MR31 system, and I by no means skilled the machine often dropping offline the best way the FS31 did.

The bottom station will ship push notifications when alarms are sounded, however the interconnected detectors will fireplace off domestically even when the bottom station goes offline.

As with its different alarms, X-Sense gives an non-compulsory subscription service referred to as Defend+ Premium ($5/month or $50/yr), which is operated by the third-party skilled monitoring service Noonlight. The service will dispatch emergency providers in your behalf if an alarm is triggered. Subscribers who expertise an energetic alarm first get a written message after which a telephone name if there’s no response to the message.
In the event you reply that there’s certainly an emergency, or if there’s no response to both of those contact makes an attempt, your native fireplace division shall be dispatched, reportedly inside 80 seconds of the alarm being triggered. X-Sense additionally gives a Defend+ Primary plan ($3/month or $30/yr) that requires you to request an emergency response your self by pushing a button the app when one of many smoke alarms goes off.
Each providers appear overpriced, since they solely supply safety from fireplace hazards and never police or medical emergencies, however in the event you don’t have a full-featured, professionally monitoring house safety system, one or the opposite plan would possibly make you’re feeling safer. We may help you resolve whether or not to enroll in knowledgeable monitoring service or take the DIY path? There was a time when you might have your Alexa-powered good speaker warn you of the sound of a smoke alarm going off in your house, however Amazon costs for that service now.
Do you have to purchase an X-Sense XS0B-MR Interconnected Good Smoke Alarm
Curiously, X-Sense’s record worth for the three-station MR31 system is $10 much less than the three-station FS31 system ($100 vs. $110), regardless of the addition of the voice bulletins characteristic. On the time of this overview, nonetheless, you might purchase both system at Amazon for $70.
The voice alerts are a superb characteristic, so I’d suggest the MR31 over the FS31 except you like that system’s smaller detectors.
