All alarm devices and local alarms shall have an automatic shut-off which will deactivate the sound, light or beacon signal of an alarm device or local alarm within one-half hour after the commencement of such sound, light or beacon signal. The police may enter the premises to deactivate such sound, light or beacon signal which has not been shut off within one-half hour of activation of same and which disturbs surrounding residents or premises. Such deactivation by police shall be taken only after reasonable efforts have been made by the police to contact the owner of the local alarm or alarm holder, or his delegate, as the case may be. Neither the police nor the town shall be liable for any damages resulting from such deactivation.
Penalty, see § 91.99
