About This Product

The Reliable Chimes Commercial Magnetic Door Switch Alarm Kit activates your selected alert accessory while a door is open. Originally developed for a customer who needed a strobe to flash only while the door remained open, this ready-to-install system also offers audible and combined alert options.

How this kit works

A magnetic switch, or a substituted closet or door switch with the same function, controls the alert through a relay. The selected accessory remains active while the door is open. This listing describes that continuous door-open operation, called “momentary” in the original listing.

For an alert on door opening or after a selected delay, with adjustable output up to one hour, see the separate timed-output kit.

Choose your alert accessory

  • Amber, blue, red, green or clear strobe.
  • Deluxe amber strobe.
  • Siren.
  • Strobe with siren.
  • Firebell.
  • Buzzer.
  • Ding Dong chime.
  • Backup alarm.

Your selected option determines the accessory supplied; the kit does not include all listed accessories.

What’s included

  • Selected strobe or other listed alert accessory.
  • At least 20 feet of wire.
  • Magnetic switch, or equivalent closet or door switch.
  • Relay to activate the accessory.

The product arrives ready to install with no assembly required. Additional wire up to 500 feet is available at an additional charge.
