The GSM alarm module is a compact, distributed control and signaling system. With the GSM alarm module, it is possible to monitor and control, for example, heating, air-conditioning and cooling systems, elevators and escalators, and all kinds of production equipment such as machinery, automated devices and conveyor belts in industrial and private building management. Additionally, the GSM alarm module is particularly suitable for remote plants, such as monitoring the heating of summer houses or the pumps of a water treatment plant. In combination with voltage relays, current relays, fuse monitors, miniature circuit breakers, residual current devices, or surge arresters fitted with auxiliary current switches or signaling contacts, there are virtually no limits to the type of monitoring tasks that can be carried out.

Changes to the 8 multi-functional bs (digital: 24 V DC / analog: 0 … 10 V AC) can be signaled both via SMS and via e-mail. The 4 digital outputs can be activated via SMS. It is also possible to b the first 4 digital bs to the 4 outputs. The GSM alarm module can be easily beterized using the accompanying configuration software, which has a simple and b structure. Parameters can also be assigned online (OTA = Over The Air) after the initial installation. The firmware can also be updated via the Internet.

The exportability of log files for the bs/outputs enables the user to obtain an overview and, if applicable, configure the processes to be better and more efficient. In the event of a power failure, the integrated maintenance-free SuperCap capacitor ensures that an error message is still sent to the pre-defined recipients via SMS.

Note:

Because the availability of mobile networks cannot be guaranteed, GSM alarm modules should not be used for safety-relevant control functions.

• Mobile monitoring and controling of electrical installations and system components
• Quick and reliable alarm message via SMS or e-mail
• Easy beter assignment and operation by means of configuration software and SMS
• Apps (for Android smartphones and iPhones) for easily reading out the status and switching the outputs

SIM card

An activated SIM card of a GSM network provider is used (e.g. T-Mobile D1, Vodafone D2, E-Plus, O2 – even prepaid cards). The card is prepared for use in the GSM alarm module in a conventional cell phone, by setting the PIN to "1234". The device can then be simply configured and put into service without any software tools or programming skills. The status of two digital bs are monitored and in the event of any change, an SMS is sent. By sending an SMS from a cell phone to the GSM alarm module you can switch the output.

Administrator

One cell telephone number has administrator rights. This administrator number is used to specify the signaling and control texts, define time responses at outputs and bs and register and store up to 5 further phone numbers in the device. An SMS alarm message is then also sent to these 5 phone numbers in the event of a fault.

Freecall function

The freecall function is an extremely interesting feature and - unlike the sending of SMS messages - completely free. It can be used for the functions of the GSM alarm module. By simply selecting the device, this function can be used to switch the output, switch it over or call up the switching states of bs and outputs. The GSM alarm module detects the phone number that is calling, checks the authorization and executes the desired function. To use this function, the anonymous call feature must be disabled on the phone being used.

Safety in the event of power failure

Any device power failure is detected by the 5TT7 120-0 GSM alarm module. The device then sends an appropriate alarm SMS and switches itself off.

Status interrogation

A status SMS can be used to query the switching state of both bs and the output. If required, the freecall function can also be used for this purpose.

Heartbeat function

The GSM alarm module automatically sends a status SMS at user-definable intervals.

User-definable device name

In the devices, users can define their own device names. This device name then prefixes each SMS. If more than one device is in use, the user can bly see where the alarm has occurred.

Power-On SMS

If required, the GSM alarm module automatically sends a so-called Power-On SMS with device name and time delay after the system is switched on. A time delay can be set for the bs. If there is a change in the device state, the alarm SMS is then not sent until the set delay time has expired.

Time delay

The adjustable delay time serves to suppress the sending of multiple alarm SMS texts, e.g. in the case of chattering contacts. This time is started after an alarm SMS is sent. No further SMS is then sent within the set time interval.

Monoflop function

This allows a time to be set after which the output is automatically reset to zero.

Password protection

If the password protection is activated, the password must be entered as a prefix to each SMS. This protects against unauthorized access.

Interrogation settings

All the settings of a device can be called up using a range of of SMS interrogations.
