Risk of electrical shock
zEnsure that the connection is secure and the circuit
breaker to the supply circuit is easily accessible when
operating the unit (e.g. fuse up to 16 A).
zDo not connect any external consumers to the fuse.
zGrounding has to adhere to the respective safety
regulations.
Device damage due to overvoltage
zConnect the unit only to current sources with the
specified voltage. Information on the power supply is
available on the power supply unit / rating plate.
Risk of panic reactions
zPrior to testing the system, make sure all important
persons involved and supporting authorities are
informed.
zTo avoid panic, all involved should be informed prior to
testing alarm facilities.
Danger of explosion
zMake sure that the battery poles do not short circuit.
zPlease pay attention to battery polarity.
zAlways fasten the battery in place with the holder
intended for this purpose.

Connect the mains power supply.
Cable type NYM 3 x 1.5 mm2is recommended.
WARNING
Personal risk and danger of device -
damage
zEnsure that the connection is secure
and the circuit breaker to the supply
circuit is easily accessible when -
operating the unit.
zSecure the device using a fuse of up
to 16 A. Do not connect external
consumers to this fuse.
zWhen working on the device,
disconnect this from the 230 V
supply and from the battery using the
intended cut-off.
1. Ensure that the mains supply terminal is de-energized.
2. Remove the mains fuse (2) Fig. 5
3. Check the protective conductor between the power
supply board and the base of the housing.
4. Connect the mains to the mains supply terminals
(ground wire E, null N and phase U).
5. Secure the cable to the clips in the rear wall using
cable ties.

A E-bus from control unit
B E-Bus to other accessories
E-Bus
Cable type IYSTY 2 x 2 x , Ø 0.6 mm is recommended.
The total length of the E-Bus cable must not exceed
500 m.
The power supply unit circuit board SMP14 and the
option (SMT12) must be connected to the central control
unit via the E-Bus (B1-, B2, B3, B4+). It may be routed in
parallel to other accessories. If shielded cable is used,
the shield may not be laid on the housing of the SAP14.
The shields of all cables must be connected at one point,
e.g. at one of the NC terminals of SMT12.
Fig. 7
Tamper contact
The tamper contact of the housing must be connected to
the SMT12 circuit board. Refer also to the installation
instructions for the SMT12.
Arcing contact
For the optional arcing contact, use the option SMZ91.

Operational setup
Before operating the system, all bus components have to
be connected to the E-bus and thus to the control unit.
Switch on the 230 V mains supply
1. Ensure that everything is correctly connected and
wired and then switch on the mains supply externally
2. Refit fuse F7.
Connect battery (Fig. 8)
1. Place the battery in the space provided in the base of
the housing
2. Mount the battery holder angle.
3. Connect the pre-installed battery cables (- blue, + red).
Fig. 9
Close and seal the housing
1. Glue the circuit diagram to the inside of the cover.
2. Engage the cover in the retainer.
3. Connect the earthing lead (1) Fig. 9 to the cover.
4. Lightly lift and close the cover.
5. Screw the cover closed.
6. Use eye (2) Fig. 9 to seal.
When the cover is opened again, e.g. for servicing, there
is no need to remove the cover completely. After
loosening the screw, the cover can be lifted gently,
swung downwards and suspended in the base.
