DUAL TEMPERATURE SENSOR
INSTALLATION AND OPERATING INSTRUCTIONS
INTRODUCTION
The Honeywell Ademco
TS300 is a hardwired temperature monitor able to accurately detect variations in temperature. It
can monitor the temperature at the unit and at a remote location (using a T280R) simultaneously. Alarm annunciations
include a local piezo sounder and two programmable NO/NC outputs which activate when the mapped high or the low
limit(s) is exceeded, protecting equipment, property, and perishable items. The NO/NC alarm outputs may be delayed by
increments of one minute to allow for expected momentary temperature variations such as during a refrigeration unit's
defrost cycle. The audible alert, if programmed, sounds when the temperature limit is violated and can be silenced with
the press of a button for a programmed duration. The TS300 can accurately monitor any temperature within the range
from 32
°
F to 140
°
F (0
°
C to 60
°
C). A T280R Remote Temperature Probe may be used to monitor temperature within the
range from -40
°
F to 140
°
F (-40
°
C to 60
°
C) or to monitor temperature in a harsh environment.
INSTALLATION
Mount the unit on a wall at a convenient viewing height. For accurate temperature sensing at the unit, do not mount the
TS300 near any heat or cooling source. If the unit does not trip the panel, insure that the contact configuration (NO/NC)
as defined in the Setup Procedure agrees with that of the zone to which it is connected.
TO THE INSTALLER
Regular maintenance by the installer and frequent testing by the user are vital to continuous satisfactory operation of any
alarm system. The TS300 and the T280R should be tested periodically, at least once a month, depending on conditions.
The installer should assume the responsibility of developing and offering a regular maintenance program to the user as
well as acquainting the user with the proper operation and limitations of the alarm system and its component parts.
Recommendations must be included for a specific program of frequent testing to ensure the system's proper operation at
all times.

SETUP PROCEDURE
Remove the front cover from the TS300. With power applied to the unit, press the SETUP MODE switch (see Illustration
A). Press the Left button to lower a numeric limit by a value of one (press and hold to decrement by tens); Press the right
button in raise a numeric limit by a value of one (press and hold to increment by tens). Pressing either button will toggle
the either/or choices. When your preferred setting is displayed, press the setup button to accept and move to the next
parameter
.
Note that, when setting High/Low limits in Centigrade mode, incrementing/decrementing will raise/lower the limit by the
equivalent of 1
°
Fahrenheit (or 10
°
F, if button is pressed and held).
