System description
Overall system
To integrate the Combi B lock into a VdS-compliant intrusion detection
system, the Combi B alarm box must be used. The box allows transmission
of a threat alert (silent alarm) and of the status message of the bolt lock
to an intrusion detection system (IDS). In addition, the operation of the
lock can be disabled via an input. Finally, the box allows permanent power
supply of the lock if a suitable supply by the IDS or a power supply is in
place.
Wiring
The alarm box makes the inputs and outputs of the lock available to an
intrusion detection system (IDS) connected down-stream. Installation and
commissioning should be performed exclusively by authorized skilled
personnel. The line resistors to be installed separately are not part of the
scope of delivery and must be soldered in accordance with the
specifications of the manufacturer of the IDS.

Installation
For installation, all components of the system (lock, input unit and alarm
box) must be free of voltage. Please remove all connections of the lock and
the batteries of the operating unit, if necessary.

The alarm box must be provided with the
required line resistors while de-energized. In the
delivery state, the terminals X1 and X2 to the
intrusion detection technology are in the close
position.
To close the spring clamps, the white sliders are
pushed toward the cable using a screwdriver.
The connected cable must then be checked for
tight fit.
Power supply
Once the lock has been de-energized, the 8-pin interface cable of the
alarm box is plugged into the "IN/OUT" socket at the Combi B lock. The 4-
pin power cable of the alarm box is plugged into the "Power" socket at
the Combi B lock.
The Combi B alarm box must be supplied with power from an external
voltage source. Either the KMH "Combi B alarm box power pack“ (article
number 3002501230) or an alternative voltage source of the required
specifications of 9-15 volts DC and max. 80mA current consumption
lock/box must be used, e.g. the supply of an IDS. The power pack or the
alternative voltage source is connected to the two terminals X1.1 (Uon) and
X1.2 (GND, see chapter Connectors) of the alarm box. Despite the power
supply of the lock by means of the alarm box ("Power" plug of the lock),
the batteries must also be inserted again into the Combi B input unit.
Without inserted batteries, a continuous undervoltage display will be
shown at the lock (see operating instructions chapter 13.3)!

Lock monitoring line via the main bolt contact
of the lock
Terminals: X2.3 to X2.8, see Connectors
Line resistors, either R105 or R106 and R107, see Schematics

The main bolt contact of the lock is part of the lock monitoring line. It
does not have to be activated, as it is always active. 
If variant A (see Schematics, R107) has been mounted, the main bolt
contact will function as NC contact. If variant B (see Schematics, R107)
has been mounted, the contact can be used as NO contact.
Further possible connections for boltwork contacts or monitoring
contacts can be incorporated in the line.
Tamper line
Terminals: X1.9 to X1.12, X2.1 and X2.2, see Connectors
Line resistors R102 or R104, see Schematics

Up to 3 further sabotage detectors (externally, optional) can be inserted
into the tamper line. The cover contact of the alarm box is part of the line.
The cover contact is actuated by closing the alarm box.
Optionally the opening monitoring line can be inserted into the loop by
means of R104.
Opening monitoring line
Terminals: X1.3 to X1.8, see Connectors
Line resistors, R101, R103 or R104, see Schematics

Depending on the structure and design of the secure storage unit, the
door contacts, monitoring lines and tamper lines can be looped in or used
as separate lines. 2 door contacts can be connected / inserted to the
connections of the opening monitoring line. Similarly, the tamper line can
be included using R104.

Silent alarm
Terminals: X2.9 and X2.10, see Connectors
Line resistor R108, see Schematics
Short-circuit bridge for variant A or alternative B on R109, see Schematics
(variant A: switch contact normally closed; variant B: switch contact
normally open)

When the silent alarm is set at the lock for the first time, the output is
switched once for four seconds for checking purposes (for the terminals
and resistors, see above).
To check the silent alarm during lock operation, an alarm code must be
entered at the lock. Unlike the actual opening code, the alarm code is
entered with ±1 at the last digit (for more details on activating and
entering an alarm code, please refer to the operating instructions Combi
B chapters 9.5 and 10.4). If wired correctly, the appropriate alarm signal
should trigger the connected system (e.g. IDS). If this is not the case, the
installation must be checked.
If a master code has not yet been activated at the lock, but the installer
code is still operating, no alarm will be triggered! More details can be
found in the operating instructions chapter 8.
NOTICE
Depending on the mounting position of the resistors in the alarm box, the
installer configures the silent alarm as NC contact (variant A, see Schem-
atics) or NO contact (variant B, see Schematics) at the terminals of the
box for the IDS.

15Mounting instruction Alarm box V2.0
The lock has a signal input. This input is inactive ex works. Via the PC
software (see PC Software Manual), the input can be configured as
remote control disable, omission alarm, override of the opening delay /
opening stand-by time or double code override (for details, see Combi B
PC Software Manual).
• If the remote control disable signal is active, the lock cannot be opened
nor reprogrammed. In this case, each key press at the operating unit of
the lock is acknowledged by the red LED flashing once.
Opening by means of the emergency key is not blocked by the remote
control disable.
NOTICE
• An omission alarm is only triggered if prior to the code input no separate
signal generator is pressed or no additional authorization is given.
• The override function of the opening delay / opening stand-by time
(OD/OST) has the effect that the opening delay time can be skipped
when a switch is actuated (see above). 
• The double code override works identical as the OD/OW override, except
that not the opening delay time is skipped, but the set double code is
replaced by a simple code when a signal is active.
Input
Terminals: X2.11 and X2.12, see Connectors
Series resistor R108 for variant A or B, as desired, see Schematics
If a master code has not yet been activated at the lock, but the installer
code is still operating, no alarm will be triggered! More details can be
found in the operating instructions chapter 8.
NOTICE

16 Mounting instruction Alarm box V2.0
• To check the remote control disable, energizing must be carried out as
described in chapter 4.2 and an opening in-tent must be carried out at
the lock (see operating instructions chapters 8 and 10).
If a signal from the red LED is received each time a key is pressed, the
disable function works correctly.
If the lock operates as usual or even is openable or programable, the
remote control disable does not work and the installation must be
checked.
With the remote control disable working, it must be checked whether it
can be disabled again and whether the lock can be opened by means of
the correct code.
• To test the omission alarm, the signal must be triggered (see chapter
4.2), a valid code must be entered at the lock and a check as to whether
a silent alarm was triggered must be carried out. This must be followed
by entering a valid code without triggering the signal prior to that and
checking whether a silent alarm (duration of 4 seconds) has now been
triggered. If this is not the case, the installation and the setting of the
lock must be checked by means of the PC software.
• To test the override of the opening delay/opening stand-by time, make
sure that the opening delay/opening stand-by time at the lock is active
(see operating instructions chapter 9.3). Now the signal must be
triggered (see chapter 4.2) and a valid code must be entered at the lock.
It should be possible to open the lock directly without starting the
opening delay. If this is not the case, the installation and the setting of
the lock must be checked. If the override is working, check whether the
opening delay proceeds as programmed if the signal is not triggered. If
the opening delay is not working properly, the opening delay
programming of the lock must be checked (see operating instructions
chapter 9.3).
• To test the double code (DC) override, make sure that the DC is active
(see operating instructions chapter 9.4). Now the signal must be
triggered (see chapter 4.2) and a valid code must be entered at the lock.
It should be possible to open the lock directly without expecting the
second code. If this is not the case, the installation and the setting of
the lock must be checked. If the override is working, check in a second
step whether the DC is requested if the signal is not triggered. If no DC
is requested, the DC programming of the lock must be checked (see
operating instructions chapter 9.4).
Depending on which functions are active (inactive ex works, others set via
the PC software), the installation must be checked as follows:
