Surveillance installation

摘要

The surveillance installation comprises both a fire extinguisher device (40) and an intrusion control device. The intrusion control device comprises a control means (21) situated in a remote control station (20), and detectors (25) linked to the control means by an alarm signal transmitter (23). A manual switching control (24) is arranged so as to provide for automatic switch-on of these devices if nobody is in the protected area and to allow manual switch-on when someone is in this area.
