B200S and B200S-LF

Sounder Bases
System Sensor B200S series sounder bases set a
new standard for performance, installation ease,
and aesthetics.
B200S Series Features
• Addressability for maximum configuration flexibility
• Two volume levels (75 or 85 dBA)
• Multiple event-driven tone outputs
• S
upports Continuous, ANSI Temporal 3, ANSI Temporal 4,
and March Time tones
• Custom tone capability with some FACP models
• A
bility to synchronize with other System Sensor
notification devices
• UL 268 and UL 464 compliant
• Pre-wire mounting plate fits various junction box sizes
• M
echanical locking feature prevents removal of attached
sensor head
• A
dditional terminal connections on Canadian model (B200SA)
enable silence feature
• 520 Hz +/– 10% square wave tone (B200S-LF)
The sounder base “listens in” to the communication between the
attached sensor head and the fire alarm control panel (FACP) to
adopt the same address as the detector, but as a unique device
type on the loop. The FACP can then use that address to command
an individual sounder — or a group of sounders — to activate. The
command set from the panel can be tailored to the specific event,
allowing selection of volume, tone, and group. In addition, some
FACPs will enable custom tone patterns.†
The B200S series sounder bases recognize the System Sensor
synchronization protocol. This enables it to be used as a component
of the general evacuation signal — along with other System Sensor
horns, horn strobes, and chimes — when connected to a power
supply or FACP output capable of generating the System Sensor
synchronization pulses.
The B200S series offers several key advantages. The sounder base
employs 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. The housing also locks with the mounting plate using two
retaining screws, for added tamper resistance.
The B200S-LF low frequency sounder base is 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 awaken sleeping occupants, even those with mild to
severe hearing loss.
