Mounting
The Manual Call Points are mounted at an easily visi-
ble location at a height of 1.4 m +0.2 m / -0.4 m.
You can find information about this in the DIN VDE
0833-2 standard and in the BHE guideline for house
alarm systems – type A. Mount the housings using
suitable oval-head screws with washers.
Countersunk head screws must not be used.
The dimension drawing shows the fixing dimen-
sions, the overall dimensions and the predetermined
breaking points for FM cable entry.
The upper and lower predetermined breaking points
on the rear wall of the Manual Call Point housing can
be opened to permit direct mounting on an FM box
or hollow-wall box (see dimension drawing; horizon-
tal distance 60 mm). Both SM and FM cable entries
are available for the cabling.

The figure shows how to connect the Manual Call
Points to a zone. Each wire is connected individually
to the designated terminal. If shielded cables are
used, the shield of the incoming and outgoing ca-
bles must be looped through using suitable means
(e.g. micro cable connecting terminals).
Two holders for fastening micro cable connecting
terminals are available on the right-hand side of the
control unit.
Ensure the system compatibility of the products.

PROJECT PLANNING AND
OPERATING INFORMATION
The mounting location is governed by the respective
standards and directives (e.g. DIN VDE 0833-2,
BHE guideline for house alarm systems – type A).
If the house alarm system is used to implement
alarm signaling as required by building supervisory
authorities, the house alarm system must be set up
based on the DIN VDE 0833-2 standard.
Manual Call Points that are not in operation must be
marked with the “out of order” sign included in the
scope of delivery.
The door labeling can be changed.
To do this, remove the door plate cover as shown
and then refit it after inserting the required labeling
plate.

IMPORTANT NOTES
The Manual Call Points are built using high-quality
electronic components and materials that provide
excellent resistance to environmental conditions.
We nevertheless recommend replacing the Manual
Call Points after 10 years of continuous operation in
order to lower the risk of limited functionality due to
external influences. Ensure that these Manual Call
Points are used only with compatible Fire Alarm
Control Panels. Fire detection systems must be
checked and maintained at regular intervals in order
to ensure that they function properly.
Observe the national procedural rules and other in-
ternationally recognized fire protection technology
standards. A corresponding risk analysis should
first be performed to determine the required proj-
ect planning criteria and then updated on an ongo-
ing basis.

IMPORTANT NOTES
Mounting and commissioning are only allowed to be
carried out by electricians. The appropriate stan-
dards, directives, regulations and specifications of
the appropriate country should be observed when
planning and setting up electrical installations.
• Protect the device from moisture, dirt and damage
during transport, storage and operation.
• Operate the device only within the specified tech-
nical data!
• Operate the device only in the closed housing.
Disconnect the device from the supply of electrical
power before mounting.
Cleaning
If devices become dirty, they can be cleaned using a
dry cloth or a cloth dampened with a soapy solution.
Never use corrosive agents or solutions.
Maintenance
Proper functioning of each Manual Call Point must
be checked at yearly intervals. Additionally,
the external intactness (particularly of the glass
pane) must be checked during the cyclical inspec-
tions or during inspections by the operator. In the
event of damage, e.g. during transport and/or stor-
age, repairs are not allowed to be made.
