Security for exterior automatic sliding doors while maintaining egress requirements Solutions for maintaining Security, Fire, & Egress requirements Troubleshooting basic automatic door issues Troubleshooting basic swinging type door issues Troubleshooting accordion type fire doors Fire, construction, & smoke barrier door labels

Often times exterior sliding doors are equipped with manual locking hardware to secure the doors after hours This creates an emergency egress problem in that the doors will not break out

Carriage Locks can be used as a stand alone feature in a retro-fit application They provide the most security when used in conjunction with exit device hardware They can be used with key-pad, RFID card readers, etc. to gain access from the outside

Provides a level of security in the path of egress Delayed Egress locks provide 15 second delay before the door will unlock, after the touch pad is activated The facility must be protected with automatic sprinklers, or smoke detectors to qualify for delayed egress locks No more than (1) delayed egress lock is allowed in the path of egress

Access control locks do not provide security in the path of egress Typically used where access INTO an area is to be controlled (doors are usually locked) Access Control locks automatically unlock in the path of egress when someone approaches the door Also by activating a manual release button The button must be mounted within 5 feet of the door

The length of the touch pad or cross bar must be at least ½ the width of the door Panic devices are tested to meet the UL 305 Panic Hardware Test Standard Must unlatch with less than 15 lbs. of force. Mechanical dogging is allowed on Panic devices

Again, the length of the touch pad or cross bar must be at least ½ the width of the door Fire exit hardware must meet both the: Panic Hardware Test Standard - UL 305 and Fire Test Standard UL 10C. Fire Exit hardware must be labeled for both Panic and Fire Mechanical dogging is Not allowed for Fire Exit Hardware Must be electronic and release when the fire alarm is activated

Perform Visual Inspection Check Your Power Check Your Fuses Test Your Switches Then Isolate the System

Check for improper clearances Check the hinges Are they loose or worn Check to see if the Jambs are plumb and square Check to see if the frame is anchored correctly Check the hardware Is it loose or misaligned

Smoke Barrier doors in many cases do not require latching hardware NFPA 101 2000 (19.3.7.5) allows for 1¾ thick, solid-bonded, wood-core doors Latching hardware is not required However, if a 20 minute fire-rated label is on the door, it must be maintained as such The public must not be misled - 4.6.12.2 NFPA 101 2000

ALL Fire doors MUST be self-closing ALL Fire doors MUST be self-latching Fire door labels carry the rating of the opening Fire door labels specify the minimum latch throw

A possible solution but, not the best The label implies the door will resist fire for 20 Min. Is ambiguous as to why it cannot bear fire label

The Best Solution! 20 Minute Fire Door Construction. For Use Only Where Positive Latching Is Not Required Makes reference to the relevant codes Field Evaluation & Labeling is available
