1. General safety instructions
1.1 GENERAL SAFETY INSTRUCTIONS
The RZ-24-05 central is a power supply with integrated tripping device for hold-open systems
on fire and smoke protection doors .
Only trained professionals may effect the installation; e.g. only a qualified electrical technician
may connect the power supply to the mains. To the electrical installation following the power
supply (safety extra-low voltage 24 VDC) apply the acknowledged technical regulations for
electrical installations. Only a professional trained by DICTATOR with an approval authoriza-
tion may approve the system.
1.2 INSTRUCTIONS FOR WIRING
The connection cables have to be installed in such a way that they cannot be moved and are
sufficiently protected against damage. Also here you strictly have to adhere to the requirements
of the respective operating company. All components of the system, the cables and their con-
nections have to be clearly marked by the installation contractor.
If nothing else is required on site or by special regulations, the following specifications have to
be respected:
All works on current circuits may only be effected in the de-ener-
gized state.
IMPORTANT
The relevant regulations must be observed for all work.
The operation of all components is only permitted in undamaged
condition.
All accident prevention regulations have to be respected.

2. General regulations for hold-open system
2.1 DEMANDS
In Germany, the installation of a hold-open system is regulated by the general building inspec-
tion approval or type approval of the DIBt. For European countries without national regulations,
EN 14637 is used as a guideline.
These regulations also govern:
the mounting positions and number of fire detectors
the position and design of the hand switch
the acceptance test (first placing in service) and marking
the recurring functional tests and maintenance
the requirements for the qualification of the persons testing and maintaining
The documents are available under www.dictator.de. The general type approval DIBt also
includes all permissible device combinations.
For further instructions on installation, use, maintenance, functional testing and servicing as well
as documentation, please refer to our operating manual for hold-open systems, which is avail-
able to our authorized specialists for DICTATOR hold-open systems.
2.2 OPERATIONAL LIFE
To ensure the correct functioning of the hold-open system, the DICTATOR smoke and heat detec-
tors have to be replaced after a maximum of 8 years of operational life. In Germany the DIN
14677 regulates the replacement obligation of fire detectors in hold-open systems.
IMPORTANT
The device combinations "RZ-24" and "RZ-24-05" have to be
mounted in the detection range of one of the fire detectors of the
respective door. If not, an additional detector is required.

4.1 MEMBRANE KEYBOARD
General Information
The membrane keyboard is slightly heated by the underlying electronics. Thus the foil surface
feels warm to the touch. When using the controller in cool rooms, the heating of the keyboard
prevents the formation of condensation water. The controller is only suitable for deep-freeze
areas if it is housed in an additional enclosure with an additional heater.
Key Reset
Key "Close door"
The "Close door" key is a 35 x 47 mm red flat key without button click, which has two functions:
Function 1: Test activation of the fire detection loop and closing of
the connected closing device.
Function 2: Resetting the triggered detectors by switching off the
loop voltage.
After pressing the button, the detection loop can only be reset after a waiting period of 3 s.
Key "Reset"
The "Reset" key is a 10 x 10 mm white key with button click, which resets the central unit when
pressed. The reset only works if the connected detectors are not triggered and ready for opera-
tion and the 3 s waiting period after pressing the "Close door" button has expired.
DANGER
Some parts inside the casing are energized with hazardous voltage
during operation! May be opened only by professionals when being
de-energized (the power supply of the RZ-24-05 is cut!!)

terminals may only be loosened with a special tool, part no. 040565, which is available sep-
arately. A normal screwdriver will damage the terminals!

5.3 CONFIGURATION OF THE DIP SWITCHES
DIP switch 1
When DIP switch 1 is set to OFF (factory setting), a tripping is stored. This means that a manual
push button release is not automatically reset and the reset button must be operated manually.
DIP switch 1 in position ON realizes the automatic reset mode. This means that a tripping is
automatically reset after 3 s when the detection loop is ready.
DIP switch 2
The DIP switch 2 in position OFF (factory setting) realizes the central closing via the external
input. For this purpose, 24 V are briefly applied to the input. Central closing can be used to
close doors (only with electromagnets) without triggering the detection loop of the RZ-24-05.
This function is not a closing in case of fire, but only realizes the closing of the fire and smoke
protection closures, e.g. at the end of the working day. The electromagnet output is switched
off for approx. 3 s when the 24 V are applied to the external input.
The DIP switch 2 in position ON enables an external reset of the central via the external input
12 or 14.

7. Functioning / Adjustment instructions for
the RZ-24-05
7.1 FUNCTIONS OF THE RZ-24-05
RESETTING the complete hold-open system af-
ter an alarm: Firstly reset the fire detectors by
means of the hand release key (1) on the cover of
the casing. For this purpose press the key longer
than 3 s. Now the entire system can be switched
back into operation with the RESET button (2) of
the central.
LED indicator "Trip"
The "Trip" LED indicator lights up red when the RZ-
24-05 detector loop is tripped. The "electromagnet"
output is switched off, the "warning light" output is switched on.
LED indicator "Ready"
The "ready" LED indicator lights up green when the RZ-24-05 detector loop is ready (not trig-
gered). The "electromagnet" output is switched on, the "warning light" output is switched off.
LED indicator "Error"
The "Error" LED indicator lights up or flashes yellow. A permanently yellow LED indicates a seri-
ous defect of the RZ-24-05. A yellow flashing LED indicates various other errors: The individual
errors are indicated by the flashing LED one after the other. The messages are separated by a
pause of 1 second (LED off).
1 x flashing = undervoltage error, i.e. the operating voltage has dropped below 15 V.
2 x flashing = flash memory error of the controller.
3 x flashing = output electromagnet overload or open.
A short flash of the LED "Error" when switching on the controller is normal and serves to test the
display.
Example: Undervoltage error and flash memory error are pending:
1 x yellow flashing, pause 1 s, 2 x yellow flashing, pause 1 s, 1 x yellow flashing, pause 1
s and so on.

7.2 TROUBLESHOOTING
Error Measure
Detection loop cannot
be reset
Check whether the RZ-24-05 can be reset with a 3.9 kΩ resistor
on terminals and 2. If not, check whether the control module is
correctly inserted in the terminal board. If the problem persists,
replace the control module. If resettable with a 3.9 kΩ resistor on
terminals 1 and 2, check the external detection loop step by step.
Is a 3.9 kΩ resistor in the last detector? Is the manual push button
reset and is a correct contact used?
Error LED lights up per-
manently yellow
Voltage from power supply too low? Please measure.
External load too high? Replace the power supply unit if neces-
sary.
Control module defective, replace it.
Key "Close door" does
not work
Replace the control module.
Key "RESET" does not
work
Replace the control module.
Electromagnets don't
work
Check the cable path from the terminal board to the electromag-
nets.
Replace the terminal board.
Warning signal does not
work
Check the cable path from the terminal board to the warning
signal device.
Replace the terminal board.
