Question:

We need several dozen different sensors for the monitoring of our data center. We want to obtain for reasons of cost, only one IP-monitoring system. How many analog sensors currently supports the Didactum monitoring system 500?

Answer:

The basic model of Didactum monitoring system provides 8 ports for analog sensors.

By mounting the Didactum expansion modules further analogue sensors can be connected.

Stand 01/2014, a single Didactum monitoring system 500 to monitor up to 96 different analog sensors.


Question:

We want to install in our storage area the  network enabled smoke sensors from Didactum. How many smoke detectors can be connected in series? Which area can be covered by a single smoke detector?

Answer:

Currently about 15 Didactum smoke sensors can be connected in series. Here, only 1 single analog sensor port on your IP-based Didactum monitoring system is occupied.

Note that the total length of the RJ12 patch cable must not exceed 150 meters. You only get a smoke alarm for the linked smoke detectors.

The table below gives you information in terms of detection range of the smoke sensor:

Question:

We have bought for our data center a Didactum Monitoring System 500. Before installing, we have connected some of the IP sensors for extensive testing. After removing the sensors, they still appear in webGUI of the remote monitoring device with status "critical“. How do I delete the previously removed sensors from the system tree of the remote monitoring system?

Answer:

Our programmers have deliberately integrated this feature integrated into all Didactum network enabled remote monitoring devices. In case of cable break, manipulation or tampering, disconnected sensors must be displayed and reported. After testing, the removed sensors can be deleted in webGUI. Just initiate a reboot of your Didactum remote monitoring device.

To do this, just go to the "System Menu" to the point "Reboot the system“. Please empty the cache of your Web browser.

The connected sensors should no longer be present in the webGUI after reboot. Alternatively, you can reset the alarm system Didactum also to factory default settings. Here, in "System Menu“ the entry  „Reset settings to default values“ is provided.


Question:

I have bought for the detection of smoke and smoldering fire in the computer room the network enabled smoke detector. How can I check this smoke detector sensor in terms of functionality?

Answer:

The networked smoke detector can be controlled with a suitable Areosol Smoke Detector Tester. Please use no burning paper or a cigarette, since the optical detection unit can be affected by smoke.


Question:

We have installed in our data center last year the water detection cable from Didactum. Now we get water intrusion alert. After inspection, we did not find any water leakage in raised floor. What might be the reason for this?

Answer:

Please remove the water detection cable from corresponding sensor and look what will happen. If you get an alarm from Didactum`s networked monitoring device, then please send the sensor to your retailer for inspection. If you get no alert, the water detection cable has been in contact with water or moisture. Then you have to clean and dry it.

Other reason can be that the environmental factor humidity (RH) is very high and vapor / moisture in on the water leakage cable. In this case you need to install a second water leakage cable in parallel , one cable connect to one contact, second to the other contact of the corresponding sensors.


Question:

We purchased Didactum`s IP-Thermometer including the IP-capable temp sensor in the form of the Monitoring System 50. Unfortunately we do not find the important function "dew point calculation" in the web interface. What can be the reason?

Answer:

In order to automatically calculate and display the dew point with Didactum`s IP-capable network thermometer, you also need the humidity sensor. If the temp sensor and the relative humidity sensor are connected to your networked remote measuring and monitoring unit, just click on the web interface under "System Tree" on the "+" icon, where you will find the element "Dew point". Here you can set individual thresholds and limits. Then you only have to set up the notifications and alerts in case of an critical dew point in your (IT) infrastructure such as eMail, SMS (via 3rd party gateway) and / or SNMP traps to monitoring software.

Question:

We have installed in our production hall several water leakage sensors under the existing radiators. Is there a way to be alerted if the sensors are sabotaged or manipulated?

Answer:

Every web-enabled remote security monitoring unit offers a so-called disconnect alarm function. If the sensor cable is cut or the intelligent sensor is destroyed by sabotage, you and your colleagues will receive a immediate alert in the form of SNMP traps, e-mail or SMS alerts (via GSM or LTE modem or Web-to-SMS server). Setting up this “sensor lost” feature is very simple: In the multilingual web front-end of the main sensor unit, go to the "Logic Schemes" menu and create a new notification or alarm rule. Here you select the corresponding sensor and define in the next selection field the status "not connected". Then simply select the desired alert function.
