EPI-TAG - How it works
Damaged or loose electrical connections can cause excessive heat and cause a fire in fuse boxes. EPI-TAG works as a patented thermal sensor and monitors the connection points.

Locations:
- Main and sub-distribution boards
- Machines and electronic devices
- Server racks in data centers
Connection option:
- Security and fire alarm systems
- Guard service and control centers “via dialers”
- Building management systems
Function:
- Triggering of the EPI-TAG at 80 ° C (± 5 ° C)
- Multiple sensors for distribution boards
- Individual sensors for machines
- Switching off and on via potential-volt free contact
1. Installation
EPI-TAG in use. Installation and activation.
1.1 Installation of the EPI-TAG
In the first step, the EPI-TAG is installed in the main electrical and sub-distribution boards, in electrical devices, in machines or in other risk areas. The installation and fastening is carried out using the supplied cable routing systems (a type of cable tie) with which both the EPI-TAG multiple sensor and the EPI-TAG individual sensors are fixed at the installation point.
The EPI-TAG is not firmly screwed to a component or otherwise integrated into the electrical system, but only lies superficially on the component to be monitored. This enables quick and inexpensive installation within a few minutes. You will find specific installation instructions with all safety instructions in our data sheets.
1.2 Connection options for EPI-TAG
After installing the EPI-TAG, you have many options for using the signal from the EPI-TAG sensors when triggered. The connection to existing and standardized systems is possible without much effort. A selection of activation options:
- Fault and fire alarm systems
- Building management system (e.g. with WAGO controller on WinGuard)
- Guard service and control center via dialing devices (e.g. Securitas)
- Shutdown of machines or power supply via potential-volt free contact
The connection is made via a potential-volt free contact and interface modules (couplers) from the respective manufacturer. You can obtain information on the required coupler from your installer.

2. Inspection and repair

2.1 Triggering from the EPI-TAG
The patented EPI-TAG sensor was developed for the thermal monitoring of electrical equipment in distribution boxes and consumers. If the monitored electrical equipment heats up, it is recognized by the EPI-TAG and the contact in the sensor is switched at 80 ° C (± 5 ° C).
80 ° C (± 5 ° C) is usually min. 10 ° C above the maximum thermal load in electrical main and sub-distributions as well as electrical consumers (devices). Some coils of contactors and other components can of course have higher maximum temperatures. In such an application example, the EPI-TAG is fixed in another position where the maximum temperature must not exceed 80 ° C (± 5 ° C).
The EPI-TAG reacts before combustion starts.
2.2 Alerting and reporting
In the event of danger, the initiation of suitable countermeasures is crucial to save human lives and material goods. The EPI-TAG triggers at 80 ° C (± 5 ° C) at a temperature at which timely action leads to little or no damage to property or personal injury. A catalog of measures is the most effective way to ensure a short response time.
- Incoming messages via the table of the hazard detection system
- Message receipt via a building management system
- Alert the control center (e.g. Securitas) using the appropriate dialing devices
- Alerting via an interface module and SMS etc.


2.3 Inspection and repair
After the alarm comes the inspection, repair of the defective connection points or the replacement of defective components. If your employee or the security guard is informed about the control center, they can use a thermal detector to localize the overheated connection point and initiate further measures.
