Unauthorized opening or manipulation of the security tab causes the immediate activation of an alert signal, which can be connected to the private security service or the police headquarters.

Protective tab
High security manhole covers made of ductile cast iron. It incorporates opening enclosures designed to guarantee the comprehensive security of the installation they house. They are equipped with an immediate warning system against any incident. Conventional manhole covers do not have a high security closing system. In cases where it is necessary to prevent its opening by strangers, a rudimentary sealing is used by welding the iron lid to the frame. This seal is not secure and damages the lid and frame.

The philosophy of high security enclosure has been aimed at avoiding any type of unauthorized access from the outside. This is achieved thanks to a tab that protects the actual lock. Opening said security tab causes the activation of a signal that can be connected to a police headquarters or a private security service.

Security lock with second alert signal for opening or tampering
Once the protective tab is open, a special key is required to open the manhole cover lock. If the lock is opened or tampered with, a second alarm signal will warn that the enclosure is open. Possibility of incorporating an opening and closing sensor, and installing a photovoltaic solar panel for power supply, unauthorized manipulation of the manhole cover and anti-panic system for emergency opening from the inside.

Anti-panic system for emergency opening from the inside. Simple, fast; without tools. Gas pistons to facilitate opening
In order to protect authorized professionals working inside, each security enclosure has an anti-panic system that allows the enclosure to be opened from the inside, without the need for any tools. The alert signal will also be activated to the central office indicating that the enclosure has been opened.

Features of the enclosure
Automatic opening from the inside can be carried out from any depth at which the operator is or, also, underneath the register (anti-panic). From the inside, the operator can proceed to semi-automatic closure without any type of tool, since when closing the register it is automatically placed in the pre-closed position, prior to total closure. Semi-automatic closing from the outside is carried out in a similar way. When closing the register automatically, it also remains in the pre-closed position, allowing convenient closing from the outside. This closure is carried out with special anti-vandal tools, the same one that carries out the opening. The remote closing control controls the opening or closing position of the register and, at the same time, the perfect closing of the system. When the opening starts, it sends a signal to the remote control, which can receive the signal from the registration system by wired circuit, by signal interruption, by GPS, radio frequency, etc. The stepped ramp closing system allows the sealing gasket to be compressed without much effort for the operator, since known systems must be screwed or threaded, not allowing closure.
