Hartte SBL-series

Electric bolts SBL-series ensure high level of security and break-in resistance. The construction enables vertical and horizontal (on the top of the frame) assembly. All electric bolts are equipped with monitoring, built-in varistor, protection against damage in case of incorrect position of doors and auto-lock function after 5 seconds of no activity. Available also in NC mode with mechanical lock for emergency opening of the bolt (for example in case of power failure). 

Characteristic:

•  fail-secure (NC normally closed) or fail-safe (NO normally open)
• mechanical strength – break-in resistance 8 000 N (800 kg) or 10 000 N (1000 kg)
• mechanical strength – opening cycles 500.000
• for mortise mounting vertically or horizontally (in top frame with bolt released down)
• varistor and locking monitoring built-in
• automatic relock after 5 seconds in case of no operation 
• prevention against locking doors in incorrect position
