1 Introduction
Thank you for buying this BLÜCHER®Connected Roof product. We hope that it will live up to
your expectations and make monitoring your roof performance easier.
All documents related to this product can be found at www.blucher.com.
BLÜCHER®Connected Roof allows you to easily supervise the performance of your roof.
The system is designed to detect a possible blocked drainage system before any major
issues occur.
The system consists of Gateway(s) and Monitors. The Monitor is mounted next to the roof
drain and collects water level- and temperature data. The Monitor sends a wireless signal to
the Gateway.
The Gateway functions as a master to the Monitors with one Gateway monitoring up to 16
Monitors. Additional Gateways must be installed if you have more than 16 Monitors in the
system.
You can set the system up in different ways to receive the information.
1) The information can be read directly on the Gateway display.
2) You can use the relay output to trigger a visual or an acoustic alarm.
3) You can use the Modbus signal to communicate directly with the Building Management
System (BMS).
4) You can apply a GSM-gateway to receive the information on your mobile phone or via
email.
This user manual and installation guide describes the installation and start-up for BLÜCHER®
Connected Roof Gateway item number #900.000.400, and how to connect the Connected
Roof Monitor item number #900.100.400 to the Gateway.

5 Mechanical installation
5.1 Gateway
We recommend that the Gateway is placed centrally in relation to the Monitors, and in line
of sight to ensure the best possible signal strength. Please note that obstructions such as
concrete and metal can reduce the signal range.
Do not install the BLÜCHER®Connected Roof Gateway in areas with a risk of water exposure and high humidity levels.
The ambient temperature should be in the range between -10 °C and 55 °C and the humidity below 80% non-condensing.
Please consider the material/thickness of the gateway enclosure for maximized signal strength.
Temperature
-10 – 55°C
Humidity
< 80% - non
condensing

Mounting instructions
To mount the enclosure:
60 mm
Min. 50 mm
35 mm
To acces
Micro SD card
Unscrew the 4 no. screws on the front cover, then remove
the front cover to access the mounting holes. The mounting
holes are Ø4 mm, and screws are not included.
Ensure there is enough free space around the unit to
enable access to the SD card, and to allow space for
the antenna and cable glands.
If there is no room for the gateway, because of the antenna, or if the placement of the gateway will disturb the signal to the
antenna, an external can be an option. Item number #900.900.000
The external has a magnetic socket and can be mounted directly on metal. If preferred it can also be glued.

Electrical wiring
In the bottom of the Gateway you can make three different electric wire connections - Relay,
Internal power and Modbus. Below you will nd the different ways to set it up.
Relay
Relay can be wired as NO or NC.
Internal power
As an alternative to the power
connector on the right side of the
Gateway, a 5V DC power supply
can be wired directly to the power
terminals.
Modbus
If connection to a Modbus RTU BMS
system is required, a suitable RS485,
cable must be used and connected to A,
B, GND. If connection to a Modbus RTU
BMS system is required, a suitable RS485
cable must be used and connected to A,
B, GND.
10 BLÜCHER®CONNECTED ROOF - REV. 02 - MARCH 2021
5.2 Monitor
We recommend that one Monitor is installed next to each drain on your roof. Monitors should
be installed at the primary drainage system and not at emergency outlets and drains. This
gives the system the best conditions to evaluate the performance of the drainage system.
