Reduced to the basics, commercial locks are designed to prevent or deter someone from entering a premises while alarms are designed to indicate when someone has already entered a premises. Locksmiths have always taken the position that a good lock, correctly installed, is the best defense against forced entry while alarm companies have thrived by telling people that a mechanical lock is not enough protection. This argument will go on indefinitely, but Schlage now has a solution for the problem which will stop the alarm people in their tracks.
The new Schlage FE51 grade 2 lever lock contains both a deadlocking latch for security and an alarm system in the same unit. The FE51 contains a sensor unit. The lockset has three different settings. The “Tamper Alert” setting is the most sensitive. Whenever the door knob/lever is disturbed, the FE51 will sound a 90 db alarm for approximately 15 seconds. The unit has modern styling which will upgrade the looks of any residential door but the element of surprise comes when a burglar moves the lever and the alarm sounds before any attempt at forced entry has been made.
According to FBI reports, an estimated 2.1 million burglaries took place in the U.S. during 2010. Burglaries are classified as the unlawful entry of a structure. Approximately 60 percent of these burglaries involved forcible entry, 30 percent involved entry where no force was used and the remaining percentage involved attempted forcible entry. Finally, the FBI states that a burglary occurred in the U.S. during 2010 every 14.6 seconds. As the alarm begins sounding after movement of the lever, a Schlage FE51 can make the difference between being another forced entry statistic or sending a would-be burglar away empty-handed.
Cutouts required in the door are identical to the Schlage “F” series locksets. The crossbore hole must be 2 1/8” in diameter and the edge bore for the latch must be a 7/8” hole. A drive-in face cap is included. The standard latch face can be removed and replaced with the round drive-in face cap. Drive-in face caps require a 1” edge bore. The “F” latch contains two hub settings and is automatically interchangeable for either 2 3/8” or 2 3/4” backsets. Replacement of an existing cylindrical key-in-knob or lever lock with an FE51 lock with built-in alarm requires no extra drilled holes or door remortising.
Two AAA batteries are required for the alarm operation. Two batteries are included in the FE51 package. The two AAA batteries must be installed in the battery brackets on the inside trim plate before installing the new lockset on the door. After initial installation the alarm function must be activated. Press the “Schlage” button inward and hold for approximately five seconds. The alarm will be set to an activated condition when the section around the Schlage button illuminates.
There are three possible alarm settings: Activity, Tamper and Forced (entry). The factory-set setting is Forced Entry.
• Activity: This setting is used to monitor doors and alert the homeowner who may be caring for either very small children, an elderly parent or someone with special needs. The FE51 alarm will beep twice whenever the door opens or closes regardless of whether the lock is in the locked or unlocked mode. After the alarm sounds, and after a three second delay, the alarm is automatically reset.
• Tamper Alert: This is the most sensitive setting. The Tamper Alert setting detects any subtle movement of the lever handle. Even though the door remains in a closed and secure position, an alarm will sound for approximately 15 seconds at a 90 decibel noise level. The alarm will sound regardless of whether the lock is in a locked or unlocked position. A built-in 60 second delay allows the building occupant to normally exit and lock the door without causing the alarm to sound.
• Forced Entry: Alarm will sound only if significant force is exerted against the door such as someone trying to kick the door in. The alarm will then sound continuously for approximately three minutes.
