to indicate and annunciate, by zone, any alarm, supervisory or trouble
condition on the system. Upon restoration of power, start-up shall be
automatic, and shall not require any manual operation. The loss of primary
power or the sequence of applying primary or emergency power shall not
affect the transmission of alarm, supervisory or trouble signals. Where
the panel controls continuous linear thermal detection cable, the panel
shall be fully compatible with the cable, as certified by the cable
manufacturer. In such applications, the panel shall be capable of
controlling multiple independent adjustable fixed temperature set points to
achieve the effect of a rate-of-rise detector. The panel shall be capable
of identifying the location of a hot spot along the length of the detector
cable and providing a constant temperature readout.
2.20.1
Zone Annunciator
Visual annunciators shall be provided for each active zone and spare zone.
A separate alarm and trouble lamp shall be provided for each zone and shall
be located on the exterior of the cabinet door or be visible through the
door. A minimum of [two] [_____] spare alarm zones that are fully
operational shall be provided. Each lamp shall provide specific
identification of the zone by means of a permanently attached rigid plastic
or metal sign with either raised, engraved or silk-screened letters. Zone
identification shall consist of a unique zone number as well as a word
description of the zone. Zones shall be arranged as shown on the drawings.

System Zoning
**************************************************************************
NOTE: Correlate the zoning of the foam system
control panel with what is shown in the riser
diagram/schematic and controls matrix shown on the
drawings. Differentiate groups of ALARM zones and
SUPERVISORY zones as well as indicate specific
devices in each circuit or zone. Generally,
separate alarm initiating zones will be for heat
detectors, waterflow switches, manual actuation
stations, etc.
**************************************************************************
The system shall be zoned as follows:
ZONE NO.

Primary Power Supply
**************************************************************************
NOTE: The drawings will indicate a dedicated power
supply circuit for each preaction and deluge
sprinkler system control panel. The power circuit
will be arranged so that power and lighting system
can be shut down for building modifications without
shutting down primary power to the control panel.
