Tattletale Portable Alarm
Smoke Detector
The remote Smoke Detector can be placed up to 2000 feet away from the tattletale unit depending on structures and objects in-between the smoke detector and the tattletale. It uses photoelectric technology to detect smoke (not heat) and it continually monitors its own sensitivity and operational status. The tattletale does not need to be armed to send a smoke alarm. The two 3V lithium betteries that are included will typically last for about 1 year.
