The FSZ Basis 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 Basis.
All of the components to be connected must be jointly listed in one type approval. 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 12 smoke switches, electromagnetic door retainers (THM) and other consumer de-
vices may be connected. The total current must not exceed 400 mA. The DIP switches 1 and 2 must
be set to OFF.
2. According to DIBt with line surveillance
The line surveillance function must be activated via DIP switch 1 (EN 14637). One termination mod-
ule 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 Basis.
All of the components to be connected must be jointly listed in one type approval.
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 400 mA. The DIP switch 1
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 1 (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 Basis.
All of the components to be connected must be jointly listed in the device list according to
DIN EN 14637 and in one type approval.

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 instructions
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, separa-
tion strips must be used in cable conduits or in cable trays. Cables and lines incoming from outside

13
9 Electrical installation
must be secured upstream of their connection sites such that the connection sites are strain- and
pressure-relieved.
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:
The maximum length of the line to the electromagnetic door retainer must not exceed 35 m and
that to the smoke switches must not exceed 75 m.
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 Basis.

If the FSZ Basis is used according to DIN EN 14637, this DIP switch must be set to “ON”.
If the FSZ Basis is used according to DIBt, the system can be used with and without line surveillance.
OFF The FSZ Basis is operated without line surveillance. A wire jumper is set across contacts 1
and 5 in the last smoke switch (observe chapter 8, section 1).
ON The FSZ Basis is operated with line surveillance. The termination module AM 142 (see
Fig. 7) resp. a magnet
1) (see Fig. 8) must be installed in the last smoke switch of a stub
and at the external manual release button (observe chapter 8, section 2 und 3). Further-
more, the external manual release button (see Fig. 7) must be connected via AM 142 to
the HAT connection terminal in the FSZ Basis.

2 stubs – DIP 2
DIP switch 2 is only evaluated if DIP switch 1 is set to “ON” at the same time.
The connection of an external manual button is not considered to be a stub.
OFF Only one stub with smoke switches is connected to the FSZ Basis. The termination
module AM 142 (see Fig. 7) resp. a magnet
1) (see Fig. 8) must be installed in the last
smoke switch (observe chapter 8, section 2 und 3). If no manual button is connected the
termination module AM 142 must be connected to the HAT connection terminal in the
FSZ Basis.
ON Two stubs with smoke switches are connected to the FSZ Basis. The termination module
AM 142 must be installed in the last smoke switch of each of the two stubs (see Fig. 9
also observe chapter 8, section 2 und 3). The total number of smoke switches must not
exceed 9. If no manual button is connected the termination module AM 142 must be
connected to the HAT connection terminal in the FSZ Basis.
1) A magnet can only be used in combination with an ORS 142!
Alarm storage – DIP 3
OFF The FSZ Basis 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 Basis returns to the
operating state. After a loss of power, the FSZ Basis also returns to the original operat-
ing state provided there is no fault or alarm.
ON The FSZ Basis stores an incoming alarm. This alarm must be reset manually via the inte-
grated 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 Basis must be reset to operate again.
