To reduce the disconnection threshold of the discharge transistor /T2 is selected with a high rate of current transfer. The load (in addition to the resistor R2) and at the same time an indicator is incandescent НL with a voltage of 1 V at a current of 75 mA. In the absence of a low-voltage light bulbs a consumer may be led АЛ307Б.

I must say that the proposed options combined metal dowels rather complicated to manufacture, but their use is justified for hollow panels and panels of partitions, which in modern buildings are not too frequent. Novosel is usually found with the need to drill or punch holes in concrete, brick and rarely in gipsolitovye panels, and requires significant skills, experience and special tools. Besides produce during operation the noise causes discomfort to the neighbors.
Of course, easier to repair in the apartment with an assistant.
