Usage
The smoke detector is used for:
- Fire protection monitoring: It detects the presence of smoke indoors and is thus a crucial element for fire prevention and safety in residential, commercial, and industrial environments.
- Installation in vulnerable areas: The sensor can be installed in rooms, building facilities, server racks, and other locations where there is a risk of smoke or fire to ensure quick detection and response to potential hazards.
These applications underline the importance of the smoke detector in increasing safety and building trust in various deployment environments.
Safety Instructions
Please observe the applicable regulations for installation in the country where the smoke detector is installed and operated, as well as the national accident prevention regulations. Also comply with any internal company rules, such as work, operating, and safety regulations.
The specified technical data and limit values must not be exceeded under any circumstances. This applies in particular to the specified ambient temperature range and the protection class according to the IP classification.
If a higher IP protection class is required for a special application, the smoke detector must be installed in a suitable housing or enclosure with the required protection class.
Requirements for the Installation Site
To ensure the proper functioning of the device, the installation site requirements specified in the "Technical Specifications" section must be observed.
Electromagnetic Interference
Interfering electrical equipment (high frequency) should be avoided.

Installation Guide
Notes on Installation
It must be ensured that the smoke detector is always mounted with the sensor head facing downwards.
In any other position, reliable smoke detection cannot be guaranteed.
The smoke detector must also be positioned so that adequate air circulation is ensured and the ventilation slots are not covered.
Installation with the Supplied Mounting Plate
The smoke detector is installed using the supplied mounting plate.
- Remove the sensor head of the smoke detector from the base.
- Attach the base of the smoke detector to the mounting plate using the supplied M4 × 10 screws.
- Reattach the sensor head to the base and turn it until it locks into place.
- Secure the mounting plate to the device frame with the 4.8 × 19 screws.
- Remove the red protective cap!
Components
The smoke detector consists of a compact plastic housing with ventilation openings.
The sensor cannot be used independently.
It must be operated together with Didactum monitoring systems.

Connection of the Smoke Detector
Connect one end of the RJ11/RJ12 cable to the monitoring unit and the other end to one of the two inputs of the smoke detector. It is possible to connect up to 10 sensors to one analog port. To do this, connect the new RJ11 cable to a free input of the already connected smoke detector and connect the other end to the next smoke detector in the chain. See the illustration below. The pin assignment of the RJ11 or RJ12 connectors is also shown in the illustration.
After starting the system and detecting the smoke detector, the LED on the smoke detector will flash weakly about once per second.
Cable assignment
Testing the Smoke Detectors
During system operation, take a needle or a paperclip and insert it into the hole in the sensor cover. Try to move it until the LED, which normally blinks weakly, lights up brightly. This indicates that the sensor is in good condition. After testing, return the sensor to its normal state. To do this, either disconnect it from the system or go to the smoke detector tab in the system interface and restart the sensor.
