Attract more attention with a strobe light and an audible alarm—the combination of visual and audible alerts helps ensure the alarm is noticed in noisy environments. These alarms sound and emit short, intense bursts of light when a door is opened without authorization. Arm and disarm with a key to restrict control to authorized personnel. Commonly used on emergency exits, restricted-access doors, and storerooms. All require a mortise lock cylinder (sold separately) for operation.

Mount an rim lock cylinder (not included) on the opposite side of the door to arm and disarm from the outside.

Arm and disarm these alarms with a programmable code. They sound an alarm when a door is opened without authorization and the alarm and magnetic contact are separated.

This lever has a bolt that locks your door when the alarm is armed. The alarm sounds when the lever is pushed to open the door. A lock cylinder (sold separately) is required to arm and disarm the alarm. You can mount an additional lock cylinder on the exterior of the door to use as a door lock.

Latch bolt projection is the length the latch bolt extends from the door's edge.

In addition to a bolt that locks your door when the alarm is armed, these levers have a latch that automatically locks the door when it's closed. The alarm sounds when the levers are pushed to open the door. A lock cylinder (sold separately) is required to arm and disarm the alarm.

This alarm plays a recorded message when it detects someone passing within 6 _1/2 feet.

Sound a mechanical chime every time your door opens, with no electricity or batteries required. A magnet and contact disc separate as the door swings open, triggering the chime. Unlike electronic door chimes, there are no wires to run. The magnetic contact sensor mounts to the door surface for easy installation. Deactivate the chime when notification isn't needed.

Use a free, downloadable app with these switches to automate alarms in your facility, such as sounding a buzzer if a trailer door is opened after a certain time. These switches link to your Wi-Fi network and push notifications to your smartphone. They have two parts: a magnet and a sensor. Mount each part to a surface—for instance, the magnet to a door and the sensor to the door frame—and the switch will send a signal when the magnet is pulled away.

Prevent unauthorized use of doors or windows with a combination of coded magnets and contacts that wire to an alarm system. The coded magnets mean they can’t be bypassed with regular magnets. These switches actuate when the magnet comes within sensing distance of the switch and reset when the magnet moves away. Mount the magnet to your door or window and the switch to the frame. Connect the switch contacts to an alarm system, which will trigger when the magnet is pulled away as your door or window is opened.
