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.
The National Fire Alarm Code, NFPA 72, requires effective January 1, 2014,
that audible appliances installed in sleeping areas produce a low frequency
alarm signal that shall be a square wave or provide equivalent awakening abil-
ity with a fundamental frequency of 520 Hz +/– 10%.
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 B200SR-LF-WH and B200SR-LF-IV sounder bases are used with address-
able detector heads. For a list of compatible sensors, refer to the System Sensor
website at www.systemsensor.com. Refer to the appropriate manual for more
information on sensors.
The B200SR-LF-WH/B200SR-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 in-
dividuals in sleeping areas. It offers maximum flexibility in configuration and
operation to meet or exceed the requirements of UL268 and UL464.
The sounder base is capable of producing either the distinctive three-pulse
temporal pattern (ANSI Temporal 3) fire alarm signal now required by
NFPA 72 for commercial and residential applications or a continuous tone
by simply removing the included jumper from the device. Additionally, the
B200SR-LF-WH/B200SR-LF-IV is designed to be compatible with existing in-
stallations of B501-Series sounder bases.
The sounder base is intended for use with intelligent systems. The sounder
base requires an external 24 VDC power supply. The connections for the
external power supply and the communication loop are isolated to prevent
electrical interaction between them. Refer to the panel manual for maximum
allowable number of units per loop.
NOTE: For NFPA72 Installations, the Temporal 3 tone should be used for public
mode evacuation.
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 mm
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
the clamping plates. For best system performance, the power (+ and -) wires
and the communication circuit wires should be twisted pair or shielded cable
installed in a separate grounded conduit to protect the communication loop
from electrical interference.
Make wire connections by stripping about
the wire. Then, slide the bare end of the wire under the appropriate clamping
plate (See Figure 1), and tighten the clamping plate screw. Do NOT loop the
wire under the clamping plate. (See Figure 2.) The wiring diagram for a typi-
cal 2-wire intelligent system is shown in Figure 5.
For system monitoring - for terminals 4 and 5, do not use looped wire under termi-
nals. Break wire run as shown in Figure 2 to provide monitoring of connections.
