The Honeywell AdemcoTS300 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).

NOTES:
1
If programmed for Normally Closed (NC) it is supervised, if Normally Open (NO) it is unsupervised.
2
The Output map is a graphical representation of the possible choices.
The left character indicates which relay you are mapping, 1 or 2.
The middle character is the local sensor map and the right character is the remote probe map. See Table 2 for
map designations.
3
Hysteresis provides a buffer so that temperature that is shifting back and forth around the alarm limit point will
not create multiple alarms. You set the # of degrees that the temperature will have to rise above the
temperature low limit set point or drop below the high limit set point for the alarm to turn off. For example, if
you set the HYS at 3 degrees and your low limit is 40 degrees, you will go into an alarm condition when the
temperature reaches 39 degrees and restore from alarm would not occur until the temperature rose to 43
degrees. Hysteresis is limited to ½ the difference in degrees between the low temperature limit and high
temperature limit or the programmed HYS setting (max of 10E) whichever is least.

The setup will NOT be lost in the event that power is lost at the panel.

Options that relate to the remote probe will only appear is you have enabled the remote probe in selection 2
of the table parameters.

High/Low limits shown in table are degrees Fahrenheit. Equivalent Centigrade temperatures apply when
Centigrade has been selected.

Hysteresis is always programmed in degrees Fahrenheit, even if Centigrade has been selected to set limits.

OPERATION
Display - The TS300 displays the selected temperature (local [ambient] or remote) in either Fahrenheit or
Centigrade as programmed. To check the temperature at a sensor, press the left button for the local sensor or
the right button for the remote probe. The temperature you have requested will flash 5 times and then return to
displaying the temperature of the sensor you have chosen to display.
Alarm - If the temperature at an enabled sensor varies outside either of its mapped limits, the audible
annunciator will sound, if programmed, and the mapped output will switch to its alarm state, but only after the
selected delay time has expired. If the delay time is set to 0 the alarm will be immediate. The maximum delay
time is 255 minutes (4 hours, 15 minutes). The output will remain in its alarm state until the temperature
returns to within the selected limits as buffered by the programmed degrees of hysteresis. As long as the
temperature remains outside the selected temperature limits, the display will cycle between the desired display
temperature and the name of the limit(s) exceeded.
Silence - The Audible alarm is silenced by pressing either of the buttons. It will remain silenced until the
silence timeout time expires and then it will become audible again. In addition, when the output delay time is in
the final 60 seconds the audible will switch to a fast beep (250mS pulsed), if it has been enabled.
High and Low Temp limits and Alarm Memory - To display the programmed high and low temperature
limits, press and hold both buttons momentarily. The unit will show the programmed limits followed by any
alarms in alarm memory. The TS300 stores the last 8 alarm events. An alarm event is one where the relay
output was activated. If delays are used, and the temperature restored before the delay time expired, it is not
considered an alarm and will not be stored in alarm memory. Alarms are displayed as the limit that was
violated. For example LLO for local low limit. The alarms are displayed most recent to oldest. Alarm memory is
cleared when you enter set-up mode or when power is cycled to the unit.
