Automatic Extinguishing
After receiving an alarm from the zone or across zones that belong to the automatic
extinguishing outputs, the extinguishing process starts. If an extinguishing delay was
defined, the delay system starts to operate. At the end of the delay the extinguishing
output (NAC A in ADR-823A or any NAC in the ADR-723) is activated. The default
duration of the extinguishing pulse is 15 seconds.
The extinguishing pulse can be configured from 5 to 55 seconds in 5 second steps; in
steps of 1 minutes between one minute to 239 minutes, or constant (that is, it will stay on
until the control panel is reset).
EN 12094
EN 12094 Requirement
See section 14.6 on page 87 for ADR-7000 EN 12094-1 compliance.
UL 864
UL Requirement
UL 864 paragraph 36.1.7 states that "An automatic delay provided prior to
release operation by a system shall be a maximum of 60 seconds, timed from
a release initiation condition, either from the actuation of a single detector, or
from the actuation of the second circuit or detector for cross-zone and single-
zone multiple-detector, or a combination of the two operations"
IS 1220
IS 1220 Requirement
Do not combine alarm verification utilizing delay and cross zone verification.
Total delay for activation of extinguishing (detector verification delay and
extinguishing activation delay) shall not exceed 60 seconds.
5.1
Extinguishing Output and Extinguishing Controller
An output device that is configured as an extinguishing controller or an extinguishing
output differs from an output that is configured as an "And" matrix in several ways:
An extinguishing can be configured to provide an extinguishing pulse with a
configurable duration or until the control panel is reset
An extinguishing output has a higher priority when allocating currents
An extinguishing output can be configured to be triggered by a single input
An extinguishing matrix may include inputs (Pressostat, Emergency Abort,
Emergency Hold, Gas flow switch, or Manual Only switch)
Activation of an extinguishing output will result in a notification that extinguishing
was activated in the control panel. Pressing the
Reset
key will not cancel this
indication in order to ensure extinguishing agent replacement or refill

Manual Activation
See chapter 8 on page 41 for a detailed explanation about device programming.

Note
The control panel supports EN 12094 "Hold" function and UL 864 "Abort"
function as per the appropriate standard requirement.
