TR-B200S-LF-WH, TR-B200S-LF-IV
Low Frequency Intelligent Sounder Base
INSTALLATION AND MAINTENANCE INSTRUCTIONS
BEFORE INSTALLING
Read
Applications Guide for System Smoke Detectors
,
which provides
detailed information on sensor spacing, placement, zoning, wiring, and
special applications. NFPA 72 and NEMA guidelines should be observed. The
National Fire Alarm Code, NFPA 72, requires effective January 1, 2014, that
audible appli-ances installed in sleeping areas produce a low frequency
alarm signal that shall be a square wave or provide equivalent awakening
ability with a funda-mental frequency of 520 Hz +/– 10%.
NOTE:
Triga Series sounder bases are not compatible with remote test
capable Triga Series detectors.
NOTICE:
This manual should be left with the owner/user of this equipment.
IMPORTANT:
The detector used with this base must be tested and
maintained regularly following NFPA 72 requirements. The detector should
be cleaned at least once a year.
GENERAL DESCRIPTION
The TR-B200S-LF-WH and TR-B200S-LF-IV sounder bases are used with
ad-dressable detector heads. Refer to the appropriate manual for more
informa-tion on sensors.
The TR-B200S-LF-WH/TR-B200S-LF-IV low frequency sounder base
generates a low frequency tone around 520 Hz. Studies have shown that low
frequency audible devices that operate around 520 Hz are more effective in
waking indi-viduals in sleeping areas.
The sounder base is capable of producing a variety of tone patterns,
includ-ing the distinctive three-pulse temporal pattern (ANSI Temporal 3)
fire alarm signal now required by NFPA 72 for commercial and residential
applications. The TR-B200S-LF-WH/TR-B200S-LF-IV offers maximum
flexibility in configu-ration and operation to meet or exceed the
requirements of UL268 and UL464 for Continuous, Temporal 3 and March
time patterns. The temporal 4 pattern meets all requirements of UL268 and
UL2075, as well as, private mode setting of UL 464.
The TR-B200S-LF-WH/TR-B200S-LF-IV can be commanded by the Fire
Alarm Control Panel (FACP) to adopt the address of the attached sensor
head, but as a unique device type on the loop. By using the address, the
FACP can com-mand an individual sounder base to activate, or a group of
sounders in a suite or other multi-room configuration. The command set
from the panel can be tailored to the specific event, allowing selection of
volume, tone, and group. The device offers two volume levels: 75 dBA and
85 dBA. The available tones are Continuous, ANSI Temporal 3, ANSI
Temporal 4, and March Time. In ad-dition, some panels will offer the ability
to command a custom tone pattern. Refer to the appropriate FACP manual
for more information.

In addition, the TR-B200S-LF-WH/TR-B200S-LF-IV is equipped with the cir-
cuitry to recognize the System Sensor synchronization protocol, enabling the
sounder base to be used as a component of the general evacuation signal –
producing an NFPA 72 compliant Temporal 3 pattern in synchronization with
compatible listed notification devices. This requires connection to a power
supply capable of generating the System Sensor synchronization pulses, a
FACP NAC output configured to System Sensor synchronization protocol, or a
separate synchronization module.
The sounder base is intended for use with intelligent systems. In addition to
being connected to the SLC, the sounder base requires a connection to either
24 VDC constant power or a NAC circuit, depending on the FACP and intended
use. The connections for 24V constant/NAC power and the communication
loop are isolated to prevent electrical interaction between them.
When connected to a NAC, power is supervised via the NAC circuit supervi-
sion while in standby mode (EOL resistor required for Class B operation).
When activated, the TR-B200S-LF-WH/TR-B200S-LF-IV provides supervision
of NAC power. (See Figure 5.)
When using a FACP equipped with a “sounder base standby power monitor-
ing” mode and constant 24 V power, power supervision EOL devices (supervi-
sion relays and resistors) should not be used. (See Figure 4.) In this case, the
TR-B200S-LF-WH/TR-B200S-LF-IV will provide supervision in both standby
and alarm/active mode. Refer to FACP installation documentation to deter-
mine if this mode is available. If your FACP does not support this mode or you
choose not to use it, power supervision relays and EOL resistors are required
to provide supervision in standby mode.
NOTE:
If the FACP’s “sounder base standby power monitoring” mode is en-
abled, connecting TR-B200S-LF-WH/TR-B200S-LF-IV low frequency sounder
bases to the NAC will result in power supervision failure when in standby.
Only connect TR-B200S-LF-WH/TR-B200S-LF-IV low frequency sounder bases
to constant 24 V power in this case. Refer to the FACP manual for maximum
allowable number of units per loop.
NOTE:
For NFPA72 Installations, the Temporal 3 tone at high volume should
be used for public mode evacuation. The use of other tone styles and low
volume level will be at the discretion of the local Authority Having Jurisdic-
tion (AHJ).
NOTE:
When not used as a supplementary evacuation system, the external 24
VDC supply shall be treated as a component of the main power supply system
and shall fall under the requirements of the main power supply system per
NFPA 72.
