Question: What are the latching features on the First Alert® OneLink® alarms?
Answer: There are two latching features on these alarms: Alarm Latch and Low Battery Latch. The latching features are an easy way to see what unit initiated an alarm or what unit is in low battery condition. Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke or CO. After smoke or CO levels drop below alarm levels, the Red LED will begin to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about 15 minutes, to give time to determine which unit initiated the alarm. Low Battery Latch is activated when the Alarm is in the "low battery condition". When this occurs, the Power LED flashes Green On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature is designed to help you identify which Alarm needs to have the battery replaced. Although, the alarm will sound the low battery chirp approximately once every minute, sometimes during the initial stages of "low battery", the alarm will chirp in greater intervals than once per minute, sometimes up to several hours, until the battery reaches a steady low battery level. This innovative feature eliminates the frustration of waiting for and/or identifying which unit is chirping.
Question: What is Optipath 360 Technology™?
Answer: Optipath 360 Technology™ is an exclusive patented feature that provides 360° of direct access to the smoke chamber. The Photoelectric sensor actually is mounted on the bottom of the circuit board so that when the alarm is installed the sensor points towards the ceiling. The sensor has virtually an unobstructed path to smoke that enters through the slots on the bottom of the alarm.
Question: Are First Alert® OneLink® alarms listed to ANSI/UL Standards?
Answer: Yes. All First Alert® OneLink® alarms are listed by ETL, an accredited NRTL (nationally recognized testing lab) to ANSI/UL 217 Standard for smoke alarms and ANSI/UL 2034 Standard for carbon monoxide alarms.
**Interconnected alarms provide added warning as compared to single alarms.
