An ounce of prevention is worth a pound of cure! 

This is even more important when dealing with security and customer service.  I continue to be amazed at the lack of security at businesses across America.  Most business, warehouses, retails stores, offices, etc. have some sort of security alarm system for monitoring after-hours, but where most fall short is during normal business hours, there is no mechanism to alert employees when someone opens a door into the facility.

Carlon's DH994 Mechanical Door Alert is easy to install and easier to maintain.  It does not require any wiring or batteries.  A closed door being opened is the perfect moment to alert you when someone enters/exits your building and is the ideal solution for homes, offices, shops and small businesses.

The product is purely mechanical.  The main unit attaches to the door frame and a small circular magnet attaches to the door.  When the door is opened, a small plunger pulls from the magnet until it releases.  This release causes the plunger to strike a small metallic plate inside the main unit, which generates the tone sound.

If you don't have a metal door frame, a metal disc is included so the magnet will attach. Simply mount the disc to the frame to align with chime magnet and your mechanical door alert system is operational.

  • Easy to install
  • No batteries or wiring required
  • Muting bar silences sound
