ABSTRACT OF THE DISCLOSURE An alarm bell assembly is provided herein, the bell assembly includes a gong and bell operating parts on a mounting, the operating parts being concealed and protected by the gong, and preferably also a cover for the assembly. The bell assembly is secured by means comprising a detector, such as a micro-switch, by which the bell is actuable when the securing means is tampered with. A rechargeable battery is connected to an external control circuit such that the battery remains fully charged and supplies the alarm drive if the control circuit connected is served. Thus the alarm bell is sounded if a prospective burglar or intruder attempts to dismantle the assembly, since the gong and the cover are secured to the assembly in such a way as to be in operable contact with the micro-switch which is connected with the power source and bell operating means. The assembly will therefore sound the alarm on being meddled with, and so serve to disturb burglars and intruders and prevent the alarm being disable.
