• emergency transmitting of the alarm message in case of one of the next emergency situations:
◦ fixation of external magnetic field influence;
◦ low internal battery charge;
◦ leak fixation (continuous consumption < 0.3 cubic meter per hour);
◦ fixation of a breakthrough (continuous consumption > 0.3 cubic meter per hour).
• there are two operation modes ("Storage" and "Operation");
• control of the battery passivation level and automatic depassivation when it is necessary.
