Linear DXS-65
The easy-to-read "help" button on Linear's DXS-65 speaks for itself. The water-resistant supervised emergency alarm transmitter has a snap-on mounting bracket, allowing it to be installed in the home, or as a silent alarm activator in an office or store. The 2.5-inch-wide unit uses two lithium batteries and has a supervisory status timer that checks battery life. linearcorp.com
