    • Good Replacement
Style: Alarm
This was used to replace another unit that had aged itself into the constant reminder beep. These dual-purpose ones seem a bit expensive but why gamble with CO. Easy to wire onto place and a decent set of instructions that explain the LED color and state of flash.
