Front battery pull tab allows battery activation without removing alarm from mounting bracket. Large mounting base makes mounting easier, protects surface paint from dirt and covers imperfections. Pre-stripped wiring harness with easy off cap does not require stripper tool. Tinned strands increase conductivity and wire nut grip. Battery run down protection will shut down alarm memory when AC power is not present, reducing low battery chirp. Dust cover protects sensor from contaminates during construction reducing nuisance alarms.
