shearlocksfor swing and sliding doorsWhat is a shearlock and how it worksA shearlock is an electromagnetic lock that combines magnetic and mechanical force, generating a holding power of up to 15.000N.It can be installed on all kinds of left and right handed doors (metal, wooden and glass), either horizontally or vertically. It is the ideal lockfor swing doors and emergency doors equipped with panic devices.A magnetic sensor detects when the door and doorframe are aligned and makes the shearlock lock the door in place. When a sherlock isdeactivated via an access control system or a button, the door is released. If, however, the door is no physically open within the T1 programmedtime (closing delay), the shearlock will automatically lock the door again. Otherwise, the door can be kept unlocked for a specifictime simply by interrupting the power supply.Shearlocks operate on 10-36V dc, so the installer does not have to set the voltage. They have two power connections and an adjustabledelay system, which means a delay between 1 and 25 seconds for realease and locking can be set.Shearlocks are designed to be connected for instant-release buttons, traffic lights, access control systems, radio alarms and even heat andsmoke detectors, in order to release the door immediately in case of fire.Example of useThere is an attempted robbery in a department store and the thief tries to escape through an emergency door with a panic device and ashearlock.When the thief pushes the panic bar, the door will still be locked by the shearlock for the programmed time, and a warning signal can besent to the store’s emergency control center. If the system is equipped with an acoustic alarm, it will be ringing for the time the shearlock isprogrammed to. When the thief discovers the door is locked, he will be forced to drop the goods.Once the door is released, the store’s security personnel will have to reset the shearlock to stop the alarm and reset the system.Different installation possibilitiesA) RimDimensionsRimModel: SH100SilverDoor only opensone waySwing doorB) MortiseMortiseDoor only opensone waySwing doorModel: SH200GreyC) Glass and swing doorsGlass doorABABMixed installationMixed installation28Shearlock for glass doorModel: SH300A) Shearlock surface mountedB) Shearlock glass doorModel: SH400A) Shearlock built-inB) Shearlock glass doorModel: SH500
Model SH-100Model SH-200Warning:Maximun space between parts = 3 mmElectrical features:Power supply:10-36 V dc, there is no need to set the voltageConsumption for 12 V dc 2A startup and 0,5 A operating current.Coil:Tropicalized.Autoprotection:If the closing manoeuvre is not executed correctly because there is a defect inalignment or there is an object preventing closure, the system tries to close severaltimes. If after five attempts the shearlock cannot be closed, it remains in theopen position and triggers an alarm. This prevents the product from overheating,which causes the deterioration of the product.Power supply connectionLEDT2 Release-delay adjustmentFOR PANIC DEVICEST1 Locking-delay adjustmentAuxiliary relay:Inversion circuit. Maximum current: 1 A at 24 V dc.When activated, the door is locked.When deactivated, the door is released.Time delays:When locking/ aligning: 4 sec.
