PLEASE FULLY READ THIS USER GUIDE!
The handling of products operating with electric current requires you to
follow the rules from VDE such as VDE 0100, VDE0550/0551, VDE 0700,
VDE 0711 and VDE 0860 or other local rules in your country.
• TowiTek modules are not designed and authorized for use in life support
or life saving applications! Do not use the product for applications in
which a temporary or permanent failure or malfunction could cause
damage to persons or propery.
• If the module is used to switch currents greater 24V it is necessary to
have the installation done with no voltage applied and performed by a
trained professional authorized for such work. The module may only be
used in such application if it was installed in a safe to touch enclosure.
• The module must only be used in dry and clean environment. The use
near water, heavy dirt and/or high humidity is dangerous and not
permitted.
• The product must not be used in conjunction with any type of flammable
liquid or gas or other environment with risk of spark triggered
explosions.
• Never exceed the limits or ratings listed in the 'Technical Data' section at
the end of this user guide.
• If the module is used in schools or educational facilities or similar
institutions the operation must be supervised by trained and authorized

Intended use for this product
The TowiTek Mini Alarm Module is a compact size alarm system based on
microcontroller technology. Its well thought features allow it to be used in
many applications.
Features of the Mini Alarm Module
• Connection of two signalling loops (with / without delay)
• Entry and exit delay on input loop #1, configurable 0 ... 30 seconds
• Alarm duration configurable from 5..120 seconds
• Alarm inputs can work with 'normally open' or 'normally closed' sensors
• Alarm inputs can work with loop resistance supervision
• Digital signal processing with microcontroller using analog/digital
conversion for loop resistance checking
Operation instructions
Learning the normal (quiet) condition for input lines
The Mini alarm module has connections for two signalling loops with two
contacts each. There are various configurations possible:
• The contacts are not connected in quiet state and connecting the
contacts will trigger the alarm (normally open mode)
• The contacts are connected in quiet state and disconnection of the
contacts will trigger the alarm (normally closed mode)
• The contacts are connected with an resistor (recommendation 2k Ohm).
Both attempts of manipulation, disconnection and short circuit of the
contacts would trigger an alarm if this mode is used.
Both alarm inputs can be used in different configuration mode if desired.
