Doors positioned in the escape routes - emergency exits - must be capable of
being opened from inside at any time easily and without the need to use exter-
nal aids. Their locks accordingly have to feature a panic function, i.e. when
actuating the internal handle, the extended lock bolt must also retract. On the
other hand, for security reasons the doors must remain locked. In many cases,
in administrative buildings, department stores, industrial plants and similar
properties, this can lead to problems. The relevant doors can no longer be
effectively monitored.
In order to gain control over this situation at reasonable cost, systems are in-
stalled which electrically lock the doors, monitor their locking status and signal
their opening or unlocking.
For opening in emergencies, this type of system - apart from certain exceptional
cases - is always equipped with an emergency switch whose actuation is swit-
ching off without delay the electrical locking elements, so enabling the door to
be passed through and initiating an alarm.
The locking elements must hold the door shut with sufficient holding force and
in emergencies, even when they are placed under preliminary load, they must
reliably unlock it. In addition, this type of system must also offer certain control
functions so that it can be temporarily or permanently released.
In addition, emergency unlocking function must also be possible by any existing
fire alarm system.
The effeff control module 1370-20 encompasses the entire electronic circuitry
required for control of an emergency exit as well as all the necessary operating
and display elements. On a parallel basis, an operating unit 1332 - for example
used as an external operating unit - and also a central control panel can be
connected to the control module.
Compliance of the units with the "Directive on electrical locking systems
for doors in escape routes (EltVTR)" (Building regulation list A part no.1
consecutive no. 6.19) has been tested by the test inspectorate TÜV
Rheinland, Cologne. Test certificate number: R 2010822
