FAQs
Is it safe to install with heavy-duty fasteners or magnetic pads?
- No, to ensure proper functioning, it is recommended to mount this alarm on any wall or ceiling with our included mounting bracket, screws, and anchor plugs.
Does this comply with the UL 217 and UL 2034 standards?
- Yes, this product is certified to meet the UL 217 and UL 2034 standards.
Can it be connected to Amazon Alexa?
- No, this unit is a traditional standalone alarm and is not Wi-Fi compatible, so it cannot be controlled via a smartphone app. If you want a Wi-Fi alarm, you should check out X-Sense XS01-WT and XS03-WX Wi-Fi smoke alarms.
How do I know that the alarm is working? Is a light supposed to blink?
- In standby mode, the LED indicator flashes green once every 60 seconds, indicating it is functioning properly.
What is the difference between the SC07 and the SC01?
- The SC07 and SC01 are combination alarms with the same basic functions but different appearances.
Does it work in non-heated hallways?
- Yes, but it is not recommended to be installed in hallways near the bathroom. This can prevent malfunction due to too much steam.
Does the ppm read the actual count, ranging from 1 to 1000 ppm, or is the readout displayed only in the alarm ranges?
- Yes, but like most units, it shows CO levels above 30 ppm (30–999 ppm). Individuals with medical conditions that may make them more sensitive to carbon monoxide may consider using warning devices that provide audible and visual signals for carbon monoxide concentrations under 30 ppm. When the reading reaches 70 ppm, an alarm will be triggered.
Does this unit come with a 10-year non-replaceable battery?
- Yes, this unit comes with a sealed lithium battery that can last for 10 years.
What is the lowest carbon monoxide ppm level that this alarm will detect?
- Like most units, it shows CO levels above 30 ppm. When the reading reaches 70 ppm, an alarm will be triggered. An alarm’s response time will vary depending on different CO levels in the air: within 60–240 minutes at a level of 70 ppm, within 10–50 minutes at a level of 150 ppm, and within 4–15 minutes at a level of 400 ppm.
Does it have a backboard for mounting?
- Yes, all accessories are provided for your installation, including a mounting bracket, 3 screws, and 3 anchor plugs.
