6 Current requirements
6 Current requirements
The FSZ Pro provides a total output current of 900 mA. This output current can be completely used
for the required components of the hold-open system. The current required for the hold-open
system consists of the sum total of all currents of the components connected.
Example calculation:
The hold-open system comprises the following components:
Smoke switch 3 x ORS 142 3 x 22 mA 66 mA
Electromagnetic door
retainer
2 x THM 425 2 x 63 mA 126 mA
Total current requirements 192 mA
The total current must not exceed 900 mA. The current consumption of the various components of
the hold-open system is specified in the related product documents.
6.1 Energy storage module ESM Pro (must be ordered separately)
6.1.1 Operating mode – buffering 24 V
The ESM Pro supports two different operating modes, which can be activated or deactivated using
DIP switch 5 (buffering 24 V).
Operation mode buffering 24 V deactivated (see page 22)<GT>
Complete system is buffered for max. three seconds.
Operation mode buffering 24 V activated (see page 23)
Only the 24 V supply voltage is buffered until the energy store is emptied.

7 Installing the FSZ Pro
The safe installation of the FSZ Pro requires only 2 holes (see annex drilling template). The FSZ Pro
is therefore delivered including two screws and dowels. The installation position can be selected
as desired. The FSZ accessories kit – which must be ordered separately – includes two mounting
adapters for installation of the FSZ Pro in a switch cabinet or on a top-hat rail. The mounting
adapters can be mounted on the rear of the FSZ Pro at the points provided.

8 FSZ Pro – applications
8 FSZ Pro – applications
The FSZ Pro allows setting up a hold-open system in three different configurations:
1. According to DIBt without line surveillance
A +24 V wire jumper must be fitted to connector 5 in the last detector to be connected (see Fig. 5).
If no manual button (HAT) is connected, a wire bridge must be implemented to the HAT connection
terminal in the FSZ Pro. If nothing is connected to the external alarm input, a jumper must also be
set there.
The connection lines of the smoke switches and manual buttons must be completely laid in a cable
conduit or cable channel. If this is not possible, the lines must be laid separately.
No more than 20 smoke switches, electromagnetic door retainers (THM) and other consumer
devices may be connected. The total current must not exceed 900 mA. The DIP switches 2 and 3
must be set to OFF.
2. According to DIBt with line surveillance
The line surveillance function must be activated via DIP switch 3 (EN 14637). One termination
module AM 142 or a magnet for ORS 142 must each be connected in the last detector to be
connected and in the manual button (see Fig. 7 resp. Fig. 8). If no manual button is connected the
termination module AM 142 must be connected to the HAT connection terminal in the FSZ Pro. If
nothing is connected to the external alarm input, a jumper must also be set there.
No more than 12 smoke switches, electromagnetic door retainers (THM) and other consumer
devices must be connected to one stub. The total current must not exceed 900 mA. The DIP switch 3
must be set to ON. Depending on the connection DIP switch 2 must set to ON or OFF.
3. According to DIN EN 14637
The line surveillance function must be activated via DIP switch 3 (EN 14637). One termination
module AM 142 or a magnet for ORS 142 must each be connected in the last detector and in the
manual button (see Fig. 7 resp. Fig. 8). If no manual button is connected the termination module
AM 142 must be connected to the HAT connection terminal in the FSZ Pro. If nothing is connected
to the external alarm input, a jumper must also be set there.

14
9 Electrical Installation
No more than 12 smoke switches must be connected to one stub. The remaining available current
can be used by any number of electromagnetic door retainers (THM) and other consumer devices.
The total current must not exceed 900 mA.
The DIP switch 3 must be set to ON. Depending on the connection DIP switch 2 must set to ON or
OFF.
9 Electrical Installation
WARNING
Risk of electric shock
The device contains unprotected contacts which may cause severe injuries through electric shock if
touched.
►The power supply cord of the device must be de-energised before assembly work is started.
9.1 Installation instruction
Installation and electrical connections may only be executed by qualified electricians or by
persons appropriately instructed with regard to electrical engineering. An interrupter (circuit
breaker, max. 10 A / tripping characteristic B) must be installed in the supply circuit. The place
of installation of the interrupter must be entered in the acceptance report .
Lines must be provided with adequate mechanical protection, properly installed and secured, and
meet the requirements present at the place of installation. For installation, the local provisions shall
have priority.
Protective conduits must generally be used in areas that are within reach of persons. On the
basis of local provisions it must be determined whether to use plastic or steel-armoured conduits.
Safety extra-low voltage lines must be laid separately from line voltage carrying lines. Therefore,
separation strips must be used in cable conduits or in cable trays.
Cables and lines incoming from outside must be secured upstream of their connection sites such
that the connection sites are strain- and pressure-relieved.

15
9 Electrical Installation
Cables must be laid separately inside the device. The jacket must be left on the cables all the way to
the terminals.
Cable type NYM 3x1.5 or 3x2.5 must be used for power supply connection.
Any commercially available communication cables with or without shielding may be used for the
safety extra-low voltage lines.
The cable cross-section must be configured according to the current consumption of the devices
used and to the line length.
Power supply connection:
The cross-section of the power supply cord must not exceed 2.5 mm².
Hold-open system wiring:
Recommended line type: without smoke switch in combination with a smoke
status indicator switch status indicator
IY(ST)Y 2x2x0,6 IY(ST)Y 3x2x0,6
IY(ST)Y 2x2x0,8 IY(ST)Y 3x2x0,8
Maximum line length:
– 35 m to the electromagnetic door retainer
– 45 m to the smoke switches (cable diameter 0.6 mm)
– 75 m to the smoke switches (cable diameter 0.8 mm)
The number of line connections should be kept as low as possible. Every required connection must
be made by means of reliable methods. Clamped connections require the use of terminals with
pinch protection.
Do not place lines directly across the printed circuit board of the FSZ Pro.

When line surveillance is switched off, the inputs for the external manual button and the external
alarm input must be bridged when not in use.
When line monitoring is switched on (see pages 28, 29 und 30), the input of the external
manual button must be terminated with an AM 142 if no external manual button is connected. If
an external manual button is connected, the AM 142 must be installed in the manual button. In
addition, the external alarm input must be bridged when not in use.
The connection cables for the ext. alarm input must be completely laid in a cable
protection conduit or cable conduit . If this is not possible, a separate cable routing is
required.

9.4 FSZ Pro - operation
The FSZ Pro can be operated according to the requirements of DIBt and/or to the requirements of
DIN EN 14637. The DIP switches in the FSZ Pro must be set accordingly.
The DIP switches allow configuring the alarm storage and line surveillance features as well as using
stubs with smoke switches.

Alarm storage – DIP 1
OFF The FSZ Pro does not store an incoming alarm. If the releasing smoke switch resets
itself or if the manual release button is no longer actuated, the FSZ Pro returns to the
operating state.
ON The FSZ Pro stores an incoming alarm. This alarm must be reset manually via the
integrated or an external reset button.
After a loss of power, the FSZ base returns to the previous operating state after the
voltage is on again. If the previous operating state was an alarm, this alarm is again
signalled. If the previous operating state was a fault or operation, the fault is indicated.
After a power failure, the FSZ Pro must be reset to operate again.
