| Fire Exit Panic Alarms | Fire exit panic alarms are used to safely secure emergency exit doors commonly found in businesses, public buildings, hospitals, restaurants and hotels.
This is accomplished by having an alarm feature as part of the locking mechanism. The panic door hardware alarm is generally powered by a 9-volt battery. A lock cylinder within the panic bar is used to turn the alarm on and off. When turning on the alarm feature, there is typically a delay of around 15 seconds. The purpose of this delay is that it allows you to turn on the alarm and exit through the door without activating the alarm.

The alarm is activated when someone
pushes on the bar attempting to use the door as a way to exit a building. Once
the alarm is tripped, it will continue to sound until it is either turned off
with a key or consumes all of the power from the 9-volt battery. When the alarm
is turned off, the alarm will not sound again until the alarm is reset by
turning the key to the “On” position and waiting for the completion of the
15-second delay.
Fire exit panic alarms are available using a self-latching feature that is part
of most panic hardware. Pushing on the bar will open the door and set off the
alarm simultaneously. When the door closes it will re-latch, securing it from
unauthorized entry. The alarm will remain sounding until it is reset with a key.
Deadbolt Style Panic Bar Alarms
Deadbolt style panic alarms are also available. With this type of alarm, one is
able to exit through the door by pushing on the panic bar, retracting the
deadbolt and sounding the alarm. This alarm also needs to be shut off with a
key. The difference with this style is that the door does not relock upon
closing. There will be outside access until the door is secured by extending the
deadbolt into the locked position and resetting the alarm. The deadbolt style
panic alarm provides more security over the self-latching panic bar. One needs
to choose the device that best suits the opening.
Keep in mind, whichever style you choose, your local building and fire
inspectors have the final word for the style that meets your local code
requirements. | |  Featured Items We Sell
