Product description
This add-on unit to the DET AC III Master includes an additional extinguisher unit. In addition to the DET-AC III unit, a DET-AC III slave unit is used for each additional bayed enclosure and supplies the extinguishing agent for that enclosure. Detection occurs via the DET-AC III master system, even when multiple enclosures are bayed together. If a main alarm is reported, the DET-AC III Master will activate extinguishing in all systems simultaneously.

Declarations
Declaration of conformity
DET-AC III Slave extinguisher system (add-on unit)

Add-on unit for expansion of an existing master system (fire alarm and
extinguisher system or early fire detection system).
The compact system occupies 1 U of rack space and is designed for
installation in the 19" level of closed server enclosure systems. It
enables extinguishing for up to 5 bayed enclosures. To be able to
activate an add-on unit, networking with a compatible master system
(fire alarm and extinguisher system or early fire detection system) is
necessary!
The master system provides for monitoring of the enclosures and sends
corresponding control signals to its add-on unit(s) to activate the
extinguishing process in case of a fire. Operation and indication of the
current system status are by way of the master system.
