INTELLIGENT EGRESS BUTTON – AN UNIQUE FEATURE OF A CONTEMPORARY KEYPAD
Most of the keypads for access control are just for controlling of “Going In” from outside. It is not enough for today’s
access control systems. In fact, controlling of “Going Out” is also very important in many public passage areas. They
are not allowed to use locks or digital keypads for stopping of “Going Out” due to safety reasons. Such as hospitals,
kindergartens, elderly homes, convenient stores, emergency exits etc.. The wardens, teachers, shopkeepers and the
guards are always required to keep an eye on people to prevent unattended leaving, shoplifting, and illegal use of the
emergency exits.
The Intelligent Egress Button can be programmed to do something to get the attention of the person on duty before the
door is opened. The button offers programmable egress delay, delay with warning, holding button required for the delay,
momentary button contact with warning for the delay and even gives alarm when a controlled door is opened.
Locations 90 and 91 below are the places for setting the desired functions for the Egress Button.
The functions programmed to the Egress Button do not affect the normal operation of the system with its keypad. For
the safety consideration, the operation of the keypad with PIN, Code or Card is always in the first priority to give instant
action to the output relay 1 for door strike.
It is NOT required to program the Egress Button with the special function in normal use. Just leave it on its default
values.
WHERE AND WHY “GOING OUT” NEEDS ATTENTION
Examples for some areas may need an Intelligent Egress Button:
Hospital:
Some of the patients are not allowed to leave the ward without doctor’s permission. An egress button with exit delay
and warning beeps will help the nurse or warden to get the attention to the door when the egress button is pressed.
Further setting of the egress button with holding contact for the delay even gives higher level of security to a controlled
door.
Kindergarten:
Young children are always active. Some of them may be willing to go out to explore their ways of playing. For safety
reason, teachers have to watch all of them in the attended area. Leaving school alone without the companion of parents
or teacher is dangerous to the young children. An egress button with delay and warning beeps will be helpful to prevent
the children trying to go out without getting the attention of the teacher.
Elderly Home:
Elderly needs constant attention and care. Some old people have poor memory. They may forget the way to come
back if they leave home alone. An egress button with delay and warning beep will easily get the attention of the warden
before the door is open.
Convenient Store:
Most of the convenient stores have just only one or two shopkeepers on duty. They are usually the cashier. Shoplifting
may easily happen while the shopkeeper is busily serving customers at the cashier desk. A holding contact egress
button with delay and warning beeps may help to stop most of the shoplifting. As the thief knows that he is gotten
attention by the shopkeeper before the door is open.
High Traffic Passage:
A short buffer time may be necessary for opening a door outward after pressing the egress button for those exits open
to a high traffic passage. An egress button with short delay and warning beeps helps the user to pay attention to the
people passing by to prevent hitting them when the door is pushed outward.
Emergency Exit:
Emergency Exit is not open to the public for daily use. It is for emergency case only. It is usually closed and watched
by the security guards. The egress button of this keypad can be programmed to offer exit delay with warning beeps and
even gives alarm output to trigger an alarm system when the door is forced to open or the door is open after the exit
delay expired. It is an useful tool to get the attention of the person on duty.
