Solenoid bolts are an ideal alternative security solution, where the use of an electric strike is impractical. Solenoid bolts from manufacturers such as Alpro and Adams Rite are suitable for sliding doors and single or double action swing doors. Their versatility means that they can be fitted to either the frame of the door or morticed into the door itself, offering the user a concealed and slimline option for door security. If using a failsafe solenoid bolt; when power is applied, it drives the bolt into the door strike which prevents the door from opening. When power is cut by means of an exit button or access control keypad, the bolt is withdrawn to allow exit/entry. Solenoid bolts use a low level of power to operate but when solenoid bolts are activated, there can be a surge in amperage, so be sure to ensure that your power supply can accommodate this
Some solenoid bolts also offer door position and bolt monitoring functionality. They can be used on timber, metal or steel doors and offer various levels of holding force. There are some solenoid bolts that offer a very high level of security and there are models that are more suited to an area that has lower requirements. Slimline versions are perfect for installing on doors with narrow stiles. They can be fitted into the head or the vertical door stile.
