TR-B200S-WH, TR-B200S-IV
Intelligent Sounder Base
INSTALLATION AND MAINTENANCE INSTRUCTIONS
BEFORE INSTALLING
Read System Sensor’s Applications Guide for System Smoke Detectors
(SPAG91), which provides detailed information on sensor spacing, placement,
zoning, wiring, and special applications. This manual is available online at
www.systemsensor.com. NFPA 72 and NEMA guidelines should be observed.
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-WH and TR-B200S-IV sounder bases are used with addressable
detector heads. Refer to the appropriate manual for more information on sen-
sors.
The TR-B200S-WH and TR-B200S-IV sounder bases were designed specifically
to meet the needs of dwelling unit applications. They offer maximum flex-
ibility in configuration and operation to meet or exceed the requirements of
UL268 and UL464.
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-WH/TR-B200S-IV can be commanded by the Fire Alarm Con-
trol Panel to adopt the address of the attached sensor head, but as a unique
device type on the loop. By using the address, the fire alarm control panel can
command 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 addition, some fire alarm panels will offer the ability to command a custom
tone pattern. Refer to the appropriate fire alarm control panel manual for more
information.
In addition, the TR-B200S-WH/TR-B200S-IV is equipped with the circuitry 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 other listed
compatible 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-WH/TR-B200S-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 (super-
vision relays and resistors) should not be used. (See Figure 4.) In this case,
the TR-B200S-WH/TR-B200S-IV will provide supervision in both standby and
alarm/active mode. Refer to FACP installation documentation to determine 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 pro-
vide supervision in standby mode.
NOTE:
If the FACP’s “sounder base standby power monitoring” mode is en-
abled, connecting TR-B200S-WH/TR-B200S-IV sounder bases to the NAC
will result in power supervision failure when in standby. Only connect
TR-B200S-WH/TR-B200S-IV sounder bases to constant 24 V power in this
case. Refer to the panel manual for maximum allowable number of units per
loop.
NOTE:
For NFPA 72 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.
WIRING GUIDELINES
All wiring must be installed in compliance with the National Electrical Code
and the local codes having jurisdiction and must not be of such length or wire
size which would cause the base to operate outside of its published specifica-
tions. The conductors used to connect smoke sensors to control panels and
accessory devices should be color coded to reduce the likelihood of wiring
errors. Improper connections can prevent a system from responding properly
in the event of a fire.
Wire sizes up to 12 AWG (2.5 mm2) may be used with the base. The sounder
base will be shipped with the screw terminals set for 14 AWG wiring. If
12 AWG wire is to be used, back out the screws to allow the wire to fit beneath
