ContactArt. 28720 / 28720N - Motorised deadbolt
High-security solenoid bolt for doors, automatic gates and overhead garage doors. Suitable for weather operation thanks to the stainless steel lock body and an internal heating system that is activated if the temperature drops below 5 °C. It is equipped with internal microprocessor control electronics, deadbolt position contact via internal relay, door position and deadbolt position control sensors, adjustable timings and a quick-connect connector. The deadbolt is rotating anti-cutting in stainless steel and features an anti-burglary device with 'total reaction' lock in the closed position. It can be operated by remote control of the gate but also allows mechanical opening and closing by manual operation with a European cylinder (hole is through on both sides). Supplied without cylinder on the inside.
N.B.: the half cylinder (40+10 mm) or the European profile double cylinder can be purchased separately.
