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
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
3
/
8
" (10 mm) 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.
CAUTION
For system monitoring - for terminals 2, 3, 4, and 5, do not use looped wire under
terminals. Break wire run as shown in Figure 2 to provide monitoring of connections.

MOUNTING
Mount the TR-B200S-LF-WH/TR-B200S-LF-IV mounting plate directly to an
electrical box. The plate will mount directly to 4" (10.2cm) square (with and
without plaster ring), 4" (10.2cm) octagon, 3½" (8.9 cm) octagon, single gang
or double gang junction boxes.
1. Connect field wiring to terminals, as shown in Figure 1 and 2.
2. Attach the mounting plate to the junction box as shown in Figure 3.
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.
CAUTION
Do not over tighten mounting plate screws; this may cause mounting plate
to flex.
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 7A. Then, install the detector. To
remove the detector from the base once the tamper-resist feature has been ac-
tivated, insert a small-bladed screwdriver into the slot from the top and press
down on the lever. (See Figure 7B). 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 TR-B200S-LF-WH/TR-B200S-LF-IV
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 FACP, command the individual TR-B200S-LF-WH/TR-B200S-LF-IV
to activate using the associated sensor address. That sounder base should
sound in approximately five seconds.
2. Via the FACP, command all TR-B200S-LF-WH/TR-B200S-LF-IV low fre-
quency sounder bases to activate using group communication to all associ-
ated 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 Sys-
tem Sensor synchronization pulses or a synchronization module.
When performing maintenance on connected smoke sensors, carefully note
the location and address of each removed sensor. When re-installed, the
TR-B200S-LF-WH/TR-B200S-LF-IV will confirm that address of the sensor
matches the address stored in the sounder base memory. If there is a mis-
match, this will be communicated to the FACP 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
TR-B200S-LF-WH/TR-B200S-LF-IV low frequency sounder base to re-enter its
address learning mode and adopting the address of the new sensor.
