General
To meet local code and application requirements, NOTIFIER® offers
standard 4" and 6" bases, as well as, specialty base designs including relay, isolator, sounder and low frequency sounder options for
the new 900 Series of addressable detectors as well as previous
generations.
The standard 4" and 6" bases offer a plug-in detector base intended
for use in intelligent systems, with screw terminals identified with a
(+ and –). The 4" base offers a compact design while the 6" base
provides compatibility with a wider range of junction boxes.
The specialty bases support application driven requirements. These
bases employ a separate mounting plate that installs on various
junction box sizes to eliminate unsightly surface-mount boxes. The
mounting plate enables pre-wiring of all connections to speed and
simplify installation.
Relay bases provide one form-C contact relay for control of auxiliary
functions, such as door closure and elevator recall. The relay can
operate in two different modes (short and long delay). The activation
time for the short delay is 60-100 milliseconds, while the activation
time for the long delay is 6-10 seconds. A shunt with pin headers,
located on the base PC board, is used to set the delay timing.
Isolator bases allow the Signaling Line Circuit (SLC) loop to operate
under fault conditions created from a short circuit preventing an
entire communication loop from being disabled. The base isolates
the section of the loop containing the short circuit from the remainder of the circuit and automatically restores when the fault is corrected.
Sounder and low frequency sounder bases are designed for new
and existing dwelling unit applications. They offer maximum flexibility in installation, configuration, and operation to meet or exceed UL
268 and UL 464 requirements. The low frequency sounder bases
are designed to meet the NFPA 72 sleeping space requirement to
produce a fundamental frequency of 520 Hz +/- 10% with a square
wave or its equivalent. Studies show that a lower frequency, centered around 520 Hz, is the most ideal to wake sleeping occupants,
even those with mild to severe hearing loss.
The B200SR sounder and -LF sounder bases (B200SR-WH/
B200SR-IV/B200SR-LF-WH/B200SR-LF-IV) are fully compatible
with existing B501BH Series sounder base installations. The device
enables users to select one of two B501-supported tones (ANSI
Temporal 3 or Continuous) through a jumper.
The B200S sounder and -LF sounder bases (B200S-WH/B200S-IV/
B200S-LF-WH/B200S-LF-IV) adopt the same address as the detector, but use a unique device type on the loop. The Fire Alarm Control
Panel (FACP) can use that address to command an individual
sounder — or a group of sounders — to activate. The command set
from the FACP can be tailored to multiple event-driven tone outputs
allowing selection of volume (75 or 85 dBA), tone (ANSI Temporal 3,
ANSI Temporal 4, or March Time) and group. In addition, some
FACPs will enable custom tone patterns. The B200S series sounder
bases recognize the System Sensor synchronization protocol. This
enables them to be used as a component of the general evacuation
signal — along with other System Sensor AV appliances — when
connected to a power supply or FACP output capable of generating
the System Sensor synchronization pulses.
