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.

Mount the housing

1. Mark the drilling position for the four external mounting

holes (A) Fig. 3.

2. Drill holes and insert plugs.

3. Screw in the screws leaving approximately 1.5 cm

proud (B) Fig. 3.

4. Snap the spacers in at the four mounting holes from

the back in the intended slots (Fig. 3).

5. Route the connection cable through the cut-outs (D) in

the back wall and hang the back on the screws .

6. Tighten the screws.

Fig. 4

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.
