This helps reduce battery drain, especially during the construction phase Provides 2 tamper-resistant options: The unit can be locked to the mounting bracket to prevent the alarm from being removed from the ceiling or wall. The battery door can also be locked to prevent battery removal. Neither option requires the use of additional components Battery door: Provides easy access, which reduces the installation time and battery replacement time.
