Ziton ZP3 Extinguishing control unit c/w ZP3 interface, 24V

ZP3-ECU2 - Addressable extinguishing control unit

Loop wired - Each Ziton ZP3-ECU2 Extinguishing Control Unit controls the discharge of a single gaseous extinguishing system, via the ZP loop wiring. The Ziton ZP fire control panel provides secure "Co-incidence Connection" control of the extinguishing control system. It is field programmable, with cross-mapped inputs being selected from various ZP line devices or zones.

Functions such as automatic extinguishing agent release delay, selection of delay/no-delay for manual extinguishing agent release, and output relay control are fully configurable. Key switches are provided for automatic or manual operation and lock-off for maintenance. Manual extinguishing agent release, an alarm silence push button and indicators for automatic, manual, locked-off, extinguishing agent discharged and reset status are also featured.

Status display at main fire panel - Outputs are provided for extinguishing agent release valves or actuators, audible fire alarm sounders, separate extinguishing agent release sounders, visual exit signs, door closing and shutter release. Also provided are facilities for remote manual release, and remote operation and status functions. Optional monitoring is provided for low extinguishing pressure, extinguishing agent release verification, and locked/ unlocked entry door status of the protected area.

The status of each Ziton ZP3-ECU2 extinguishing control unit is displayed at each fire control panel. A fault signal indicating the type of fault is raised at the fire panel for any out-of-normal conditions, which exits at the ZP3-ECU2 extinguishing control unit. Monitoring is provided for power supply, fuses, and operation. Field wiring is monitored for extinguishing agent release valves/actuators, fire sounder, and manual extinguishing agent release units.

Double address line security option - Any number of Ziton ZP3-ECU2 extinguishing control units may be used on a ZP fire detection system, with each unit requiring two system addresses. The Ziton ZP3-ECU2 unit may be connected to a single Ziton ZP system address line, or it may optionally be connected to two Ziton ZP system address lines, providing additional security against an accidental discharge. The casing of all Ziton ZP3-ECU2 addressable extinguishing control units must be earthed to building earth. Units require a 24V DC supply which may be taken either from the main system or from an external PSU.
