Product information " Smoke, Humidity and Temperature Sensor "

The Didactum Sensor AC (alternating current) has been developed specifically for the network based surveillance of AC power. This highly reliable sensor monitors the AC voltage that is providing the critical power to your infrastructures. This sensor is compatible with all Didactum Monitoring Systems
The fact that all of these sensors are housed in a single casing prevents the possibility of any wires getting tangled due to the wiring of individual sensors. It also allows for a clean and simple installation as this is a combined smoke detector, humidity and temperature sensor in one unit.

This sensor unit is connected via the included RJ-12 patch cable to a CAN bus port on your Didactum remote monitoring system. Thanks to the simple CAN bus principle CAN individual sensors or other sensor units from the Didactum base unit can be connected in series.

You can also extend this sensor up to 200 meters from the Didactum monitoring system.
Smart multi monitoring

Addressable sensor lets you remotely monitor smoke, humidity and temperature in any location in the data center from internet

Embedded temperature sensor

Allows you to measure temperature without additional sensors

CAN ports

Simplifies installation and management by connecting to any other extension units or to master unit directly


Sensor provides 3-level user authentication

Easy Installation

Simply connect sensor to any CAN output. Processors - we use NXP


At installation indoors, inside the rack etc., sensor monitors occurrence of smoke, temperature and humidity inside the building. Automatic restoration of power after the actuation. Max. distance from the monitoring unit is 200 meters.

Mounting There are mounting holes on the bottom of the case for fastening. Fasten sensor, connect CAN inputs to the input of the previous CAN unit, sensor or of the monitoring unit. The red LED lights up.

Match the bus terminators of the CAN units. Switch terminator TR in ON position on the monitoring unit and on the last CAN unit, TR on intermediate CAN units are in Off (1,2) position. Maximum 8 CAN units, sensors and/or devices can be on one CAN bus.
Connection To connect sensor unit to the system, log into the interface -> Preferences -> Can Config -> CAN1 or CAN2 (depends on which physical port CAN1 or CAN2 of the system the unit is connected).

Click Config button and wait. The system will poll the bus CAN and give rows with data, if successful will write: Done!. CAN modules and sensors will appear in the list. Click Apply and then click Restart.

Go to --> System Map / Floor Map, click Refresh button, or wait, new devices and new sensors will appear in the tree. Green LED will light up when CAN sensor is connected and successfully determined by the system.

Connection is not successful if after clicking Config, the poll is reset before the phrase "Updating". Check whether terminators on the bus line are set in the right position, change their position using TR switch if needed.
Supply includes Sensor, 3-wired shielded patch cable RJ12 (2m), bracket, 2 screws and 2 nuts M4, 2 screws 4.8×20mm, double sided sticker.
