Connectible external systems
Previdia series control panels have been especially developed and designed for connection to various systems which
are external to the fire detection system itself, such as:
•BMS (Building Management System):
supervision systems, usually comprising
software installed on a PC platform, capable
of supervising and managing the system
through graphic maps, function keys, etc.
These systems constitute an easy-to-use
interface for end users.
•Pager: systems comprising a PABX capable of
receiving text messages from other systems
(in our case from fire-detection control
panels) and forwarding them to remote
devices such as pagers or displays of cordless
telephones.
•Video surveillance with IP cameras with
Onvif protocol: cameras installed in the same
Ethernet network can be interconnected with
the fire-detection control panel in order to
provide images captured in ambients where
dangerous situations have been detected (in
the case of PTZ bu positioning the camera at
the correct angle).
The images, visible on the control-panel
console or from remote locations (via e-mail
or web browser), provide a valid verification
tool that allows the user to establish the
seriousness or irrelevance of fire signalling.
•Voice Evac: voice evacuation systems
comprise one or more control units
(controller, amplifiers, power supplies) and a
series of sound diffusion lines.
These systems have the task of warning
occupants of the necessity to evacuate the
building and are more effective that sounders,
as they are capable of providing detailed
information regarding the fire.
The interconnection of these systems and the
fire detection system allows the activation of
accurate voice messages relating specifically
to the various zones in the building.
