| 摘要 |
The invention concerns an intelligent alarm apparatus with interfacing to a telephone network, comprising of an alarm sensor (2), which is directly connected at a high impedance level via an integrator (2) and a detector (3) to the interrupt input of a processor (4) waiting in a power-saving mode. The interrupt generated to the processor (4) is adapted to activate an alarm transmission to an alarm control point. A power supply section (5) of the apparatus is connected to a telephone line (6), from which the apparatus obtains its power feed. |
