The basic burglary protection device used in KRISPOL grilles is a BOLT LOCK fixed in the bottom curtain strip on the inside. The device makes it impossible for unauthorised people to lift the grille from the outside, if bolted.
LOCK MICRO-SWITCH - used in electrically powered rolling grilles.
When the lock is in place, the grille cannot operate.
EMERGENCY BRAKE - to prevent sudden uncontrolled fall of the grille.
EDGE PROTECTION (optical or pneumatic) - an additional accessory fitted in electrically powered rolling grilles. The protection is used to protect against crushing.
When the grille comes up against an obstruction (e.g. a cardboard box) while being closed, it stops automatically and then travels up.
PROTECTION AGAINST ROLLING ON THE SHAFT - used in electrically powered grilles.
Thanks to the protection, the rolling grille stops automatically whenever an undesirable element gets into the grille.
PHOTOCELL SENSORS - an additional accessory available for grilles.
They are used to protect against crushing.
The grille lifts automatically if any obstruction is detected by photocell sensors.
