With the Hanna Products Mail Chime, you simply mount a sensor on your mailbox door using double sided tape (included) and plug the Receiver into an electrical outlet anywhere in your home. When the mailbox door is opened, the Mail Chime beeps four times. And, in case you missed the beeps, a bright red LED light will tell you the mail has been delivered. You’ll love the convenience of knowing when your mail is delivered.
The Mail Chime is only designed to be used on the three basic types of mailboxes; i.e. the curb side, wall mount and the slot type mailboxes. It is not designed to be used on mailboxes with vertical hinges such as cluster type community mailboxes.
