WArrAnTy conDITIons
These operating instructions are an integral part of both the device and our terms of
warranty. They must be handed over to the user. The technical design of the appliance
is subject to change without prior notification.
PEHA
products are manufactured
and quality-checked with the latest technology according to applicable national and
international regulations. Nevertheless, if a product should exhibit a defect,
PEHA
warrants to make remedy as follows (regardless of any claims against the dealer to
which the end user may be entitled as a result of the sales transaction):
In the event of a justified and properly established claim,
PEHA
shall exercise its
prerogative to either repair or replace the defective device. Further claims or liability
for consequential damage are explicitly excluded. A justifiable deficiency is deemed to
exist if the device exhibits a structural, manufacturing, or material defect that makes it
unusable or substantially impairs its utility at the time it is turned over to the end user.
The warranty does not apply to natural wear, improper usage, incorrect connection,
device tampering or the effects of external influences. The warranty period is 24 months
from the date of purchase by the end user from a dealer and ends not later than 36
months after the device’s date of manufacture. German law shall be applicable for the
settlement of warranty claims.
DIsPosAL oF The DeVIce
Do not dispose of old devices in the household waste! The device must be
disposed of in compliance with the laws and standards of the country in which it
is operated! The device contains electrical components that must be disposed
of as electronics waste. The enclosure is made from recyclable plastic.
DescrIPTIon
The in-wall input module is designed for the decentralised application of the PHC
system. The PHC bus is extended for that from the distributor to the installation site
of the in-wall module.
The in-wall module without frame features eight external inputs (
I
0-
I
7
). PHC in-wall
button modules (941 UP o.A.) can be connected for feedback at all inputs and PEHA
buttons (550 LED/PHC) can be connected at the (
I
4-
I
7
) inputs. The LEDs of these
buttons can be switched ON and OFF by the PHC system without additional wiring.
The maximum allowed line length between buttons and the in-wall module is 25
metres for the 24 Volt inputs and 5 meters for the 5 Volt inputs of the in-wall module.
No more than one switch may be connected to the
I
0 input. It is also possible to connect
one switch to the
I
0 input and a motion detector at the
I
3 input. Otherwise only buttons
are permitted! A feedback with switches is not possible.

MounTIng
The installation of the PHC modules may be carried out by authorised technicians
only. During installation the system‘s electricity has to be switched off. The PHC in-wall
module without frame is designed for installation in a 60 mm in-wall box. If installing
the in-wall module into a deep 60 mm in-wall box it is even possible to install the
in-wall module behind a button.
Attention!!
The PHC modules may
not
be employed in connection with devices that
may endanger people, animals or property when operated.
The following points must be observed:
- the valid laws, standards and regulations
- the technical state of the art during installation
- the PHC manual and the operating instructions of the PHC modules.
- Operating instructions can only cite general stipulations.
These are to be viewed in the context of a specific system.
The following systems may not be switched by Phc output modules:
- safety switches such as EMERGENCY OFF
- emergency power supplies
- fire alarm systems
- emergency lighting systems
DATA connecTIon
The PHC in-wall module without frame requires the PHC BUS that serves as data
connection and as voltage supply. The connection from the in-wall module to the
control unit and to other modules is usually made by a JY(ST)Y line of 2x 2x 0.8 mm
Ø and may have a length of no more than 1000 metres. When connecting the BUS
line be sure that the lines A and B are not crossed.
The PHC module can be positioned anywhere in the data line. Power needs to be
switched off before disconnecting the bus line.
coDIng sWITch
The input module‘s address is set by the coding switch built into the PHC control
module. The setting of the coding switch is presented in the PHC software under
the menu item „
Components
g
Edit Modules
“. Make sure that no identical module
addresses are given for PHC input modules. The setting of the coding switch may
be carried out by technicians only. For this the PHC module needs to be switched off
and it must be ensured that there can be no electrical discharge.
currenT consuMPTIon
The current consumption of the input module depends on the type and number of the
connected command devices:
Own consumption: ............................................................................................15 mA
