BEFORE INSTALLING

Please read the System Sensor Smoke Detector Application Guide, which pro­vides detailed information on sensor spacing, placement, zoning, wiring, and
special applications. Copies of this manual are available from System Sensor.
NFPA 72 and NEMA guidelines should be observed.

NOTE: 200 Series sounder bases are not compatible with remote test capable
200 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 B200S sounder base is used with System Sensor 200-Series sensor heads or
equivalent. 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 B200S sounder base was designed specifically to meet the needs of dwell­ing unit applications. 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 a variety of tone patterns, including
the distinctive three-pulse temporal pattern (ANSI Temporal 3) fire alarm sig­nal now required by NFPA 72 for commercial and residential applications.

The B200S can be commanded by the Fire Alarm Control 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 B200S 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 System Sensor 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. In this scenario, the sounder bases will have the ability to synchronize
with other System Sensor horns, horn/strobes, and chimes using the same
power source.

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 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 specifica­tions. 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
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.

FIGURE 2:

Make wire connections by stripping about 3/8” of insulation from the end of
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 typical
2-wire intelligent system is shown in Figure 4.

TAMPER RESISTANT FEATURE

NOTE: Do not use the tamper-resist feature if the removal tool is to be used.
This detector base includes a tamper-resist feature that prevents its removal
from the base without the use of a tool. To activate this feature, break the tab
from the detector base as shown in Figure 6A. Then, install the detector. To
remove the detector from the base once the tamper-resist feature has been
activated, insert a small-bladed screwdriver into the slot from the top and
press down on the lever (see Figure 6B). This allows the detector to be rotated
counterclockwise for removal. The tamper-resist feature can be defeated by
breaking and removing the plastic lever from the base. However, this prevents
the feature from being used again.

TESTING AND MAINTENANCE

Sensors and bases must be tested after installation and as an integral part of a
periodic maintenance program. Test the B200S as follows:

NOTE: Before testing, notify the proper authorities that the smoke sensor
system is undergoing maintenance and, therefore, will be temporarily out of
service. Disable the system undergoing maintenance to prevent unwanted
alarms.

1. Via the fire alarm control panel, command the individual B200S to activate
using the associated sensor address. That sounder base should sound in
approximately five seconds.

2. Via the fire alarm control panel, command all B200S sounder bases to acti­vate using group communication to all associated addresses. All devices on
the loop should sound, and if a temporal tone is commanded, the tones can
be synchronized to each other.

NOTE: Synchronization requires a power supply capable of producing the Sys­tem Sensor synchronization pulses.

When performing maintenance on connected smoke sensors, carefully note
the location and address of each removed sensor. When re-installed, the
B200S will confirm that address of the sensor matches the address stored in
the sounder base memory. If there is a mismatch, this will be communicated
to the fire alarm control panel and the sounder base can be commanded to
chirp at regular intervals until the correct head is installed.

If a replacement head is installed or address changes are required, the mis­match may be resolved at the panel by commanding the B200S sounder base
to re-enter its address learning mode and adopting the address of the new
sensor.

3. To mount the sounder base, hook the tab on the sounder base to the groove
on the mounting plate.

4. Then, swing the sounder base into position to engage the pins on the
product with the terminals on the mounting plate.

5. Secure the sounder base by tightening the mounting screws.

6. Install a compatible smoke sensor as described in the installation manual
for the sensor.
