2. Wiring diagram
The deBus supports a maximum of 32 devices. The amount of necessary power supplies is
depending on the application (e.g. if shutters are used or not). In this example an SNG3
adapter is used to connect the data line to the HOST.

3. General
proxSafe mini is part of a keyTag management system.
With proxSafe mini you can handle up to 8 proxCylinders in one device.
Connection of the proxCylinders is done by RJ45 connectors.
Each proxCylinder contains of the following devices:
• Relay for keyTag release
• Coil for keyTag identification
• Red LED for optical signalisation
• End switch for detecting, if the proxCylinder is occupied
UB: 13,8V/DC
proxSafe has a serial interface for communication:
RS485, 9600 Baud, no parity, 1 stopbit, 8 bits
Protocol: deBus
The following parts of the proxSafe can be controlled by the host:
• Beeper
• Yellow LED
• Red LED main board
• Red LEDs proxCylinders
• Relay proxCylinders
• Lock
• Motor
Following states are controlled by the main board:
• Tamper
• Low voltage
• Device alert (shutter blocked)
• Status lock
• Status cabinet (open, closed, in move or undefined)
• Status end switch top
• Status end switch bottom
• Voltage on antenna of the proxCylinders
(only after reset or after command “Get Image”)

4. Implementing hints
You will find the implementing hints in the debus protocol for the proxsafe mini (available
on request).
5. Shutter is blocked
If the terminal gives a signal to the multiplexer to close the shutter and the shutter is blocked,
the multiplexer tries closing the shutter for three times. If the third attempt failed, the shutter
remains in this position. The device alert flag is set (see error codes in debus protocol
description). The beeper of the multiplexer is activated regularly for a short time. The beeper
can be deactivated by sending a “Set Output”-command with TIM = 0x00 and StdIo =
virtual beeper. The device alert flag is not influenced by this command. The device alert flag is
reset by sending the “Reset Status”-command or if the next closing of the shutter succeeds.

6. Emergency unlock
If normal operation failed (e.g. processor does not work) to get keys out, an emergency
unlock is integrated. The components for emergency unlock are at the backside of the
proxSafe mini.
The first step is to open the shutter. The shutter is protected against opening by hand.
For this reason in case of emergency the jack (red marked in the picture above) must be
connected to the emergency opening box with the 2-pole cable (enclosed) as follows in
order to unlock the shutter:
While the jack is connected and the switch of the emergency opening box is being pressed constantly, the shutter can be opened by hand using a tool (for
example a screw driver).

After the shutter has been opened this way, in a second step the emergency unlock for the
proxCylinders must now be activated separately as follows:

emergency unlock
To activate this emergency unlock, the jack (red marked in the picture above) must be
connected to the emergency opening box with the 4-pole cable (enclosed) as follows:
While this jack is connected and the switch of the emergency box is being pressed constantly, all keys can be taken out.

7.3 FCC Notice
To comply with FCC part 15 rules in the United States, the system must be professionally
installed to ensure compliance with the Part 15 certification. It is the responsibility of the
operator and professional installer to ensure that only certified systems are deployed in
the United States. The use of the system in any other combination (such as co-located
antennas transmitting the same information) is expressly forbidden.
