Estimating the term…
A building has at least one security guard post to control the secured building exits, each of which has an unlocking instrumentality, without forbidding their emergency use. When activating the unlocking instrument to open a secured exit, there is a transmission of information to the security guard post and an initiation of a delay during which the security guard can forbid the opening of the exit. The unlocking instrument can also visually indicate events at the exit. The apparatus has an electro-mechanical lock, a sensor which is sensitive to motion of the unlocking instrument, a control line linking each door to be controlled to the security guard post, and a central electronic processing unit. A surveillance circuit responds to the sensor. A security circuit frees the unlocking instrument when a fault is detected.
A process to control emergency exits in a building comprising at least a security guard post, each emergency exit being provided with an unlocking component, means responsive to an activation of the unlocking component for opening the emergency exit for generating an interrogation signal which initiates a request for information from the security guard post, means responsive to said interrogation signal for setting off a first time delay To during which the security guard may forbid the opening of the exit of concern during a second time delay Tc, means for normally opening the exit at the end of the first time delay To in the absence of guard intervention, and means responsive to an intervention by the security guard for delaying the opening until the end of the second time delay Tc.
An apparatus for the control of exits provided with an unlocking component such as an anti-panic bar, of the type having an electro-mechanical apparatus for blocking the unlocking component, a sensor which is sensitive to motion of the unlocking component, a command and control line connecting each of the exits which are to be controlled to a security guard post, and an electronic system located at the security guard post and having a sensor surveillance circuit, said electronic system being connected to said command and control line, a security switch which frees the unlocking component when a fault appears, surveillance camera means at each of the exits which is located out of sight of the security guard post, an electronic system having a display apparatus connected to the different cameras via a video selection component, said display apparatus uniquely identifying the camera giving a picture as it is being displayed, and means responsive to a reception of a request signal from a sensor associated with an exit for enabling a security guard to select the picture being supplied by the camera surveilling the exit.
