Security for School Perimeter Doors

Nov 30 / Dan Keller





Schools are complex buildings that have multiple perimeter entry points.  These portals of entry include primary entry doors, visitor entry doors, secondary entry doors, event entry doors, emergency exit doors, and maintenance and service doors.  The security of perimeter doors should be the number one security priority for K-12 schools.

Every school perimeter door should be locked and secured at all times whenever it is not being directly monitored by a school staff member.

School perimeter doors should either be electronically controlled, requiring an access credential to gain entrance, or electronically alarmed and monitored to identify, by electronic sensors, whether the door has been propped open or the locking mechanism appropriately engaged.


One of these two types of security systems should be functional for every school perimeter door.


School perimeter door electronic security systems must be monitored on a real-time basis whenever a school is occupied. This usually occurs in the school’s administrative office. Whenever a school perimeter door security alarm is activated, it is vitally important that a timely response occurs.


Vision panels, sidelights, or other glazing in close proximity to school perimeter doors should be equipped with forced entry laminate glazing, bullet resistant laminate glazing, or security film.


Primary and secondary school perimeter doors should be electronically access-controlled requiring an access card or credential or biometric feature to gain access and electronically alarmed and monitored to identify if the door has been propped open or the locking mechanism properly engaged.


Door propping and latch engagement alarms should be both locally audible and centrally monitored at the school administrative office.


It is vitally important that school staff in the administrative office are able to real-time monitor door propping and latch engagement alarms and ensure a timely response to their activation. Failure to do so voids the benefit of these perimeter door alarm systems.


All school perimeter doors should be within view of video surveillance cameras.


Electronic access-controlled perimeter doors should have a call-in intercom adjacent to the door exterior.


School perimeter doors should be either aluminum or hollow metal or fiberglass.


School door frames should be ANSI (American National Standards Institute) Grade 3.


Unless they may possibly be designated for “reverse evacuation”, emergency exit doors should have no exterior door hardware or trim for intruder leverage.
