ADEMCO 5821
Temperature Sensor &
Flood Detector
INSTALLATION AND SETUP GUIDE
GENERAL INFORMATION
The ADEMCO 5821 Temperature Sensor & Flood Detector
is a wireless transmitter used with ADEMCO alarms
systems that support 5800 series devices. The 5821 can be
configured to operate as either a Temperature Sensor or
Flood Detector. The 5821 in combination with the
ADEMCO T280R is ideal for monitoring refrigerators and
freezers in restaurants, kitchens and warehouses where
food storage is a concern. The 5821 will send an alarm to
the control when the set temperature limit is exceeded or
when a flood is detected protecting equipment, property,
and perishable items via it’s rf transmitter.
Temperature Sensing is measured by an internal sensor, or
externally using ADEMCO T280R probe, or both. Flood
detection is accomplished using external probe ADEMCO
470PB with the supplied resistor.
When the temperature either increases past the high
threshold limit and delay (30 minute delay) or below the low
temperature threshold limit and delay (30 minutes) an
alarm is triggered. This preset delay offers greater
reliability against false alarms due to normal usage of
refrigeration equipment.
MODES OF OPERATION
The refrigeration mode of the device can be used to monitor
refrigerator or freezer equipment that keep perishables
below a set temperature point. The warm temperature mode
of the device is used to warn of a high temperature
condition, protecting temperature sensitive equipment and
operations. When the temperature rises to the set point
temperature, an alarm is sent.
Setting the temperature for Alarm.
When the set temperature limit is exceeded, the appropriate
predefined time-delay begins. At the end of the delay, the
alarm is sent.
The 5821 can be used to operate in several modes as follows:
• Report room air temperature has fallen below 45°F.
• Report room air temperature has exceeded either 75°F
or 95°F as selected via the positioning of Dip Switch 1
and 2.
• Monitor and report temperatures above 10°F or 42°F
using ADEMCO External Sensor Probe T280R as
selected via the positioning of DIP Switch 1 and 2.
• Monitor and report the presence of water using
ADEMCO External Probe 470PB with supplied resistor
as selected via the position of DIP Switch 2.
The 5821 also feature a tamper switch, which causes a
trouble signal to be sent to the control if the unit’s cover is
removed from the base.
The Tamper switch is also used when programming the
unit’s serial number at the control.
The 5821 is powered by a 3-volt lithium battery. If the
battery voltage gets too low, the 5821 sends a low battery
signal to the control panel.
Installing/Replacing the Battery
Important Notes:
• Use 3-volt lithium battery:
Duracell DL 123A or
Panasonic/Sanyo/Varta CR123A.
• Observe polarity.
• When replacing the battery, wait at least 30 seconds
after removing the old battery, before installing the new
one.
1. Remove the transmitter's top cover by inserting the flat
blade of a small screwdriver into the pry-off slot at one
end of the unit (see Fig. 1 for location), and slightly
twisting the blade until the cover disengages.
2. Install a 3-volt lithium battery as shown in Figure 1.

PROGRAMMING THE UNIT
Prior to programming the device you must choose an
operating mode. Refer to Table 1 for the applicable
operating mode. The transmitter’s serial number must be
enrolled in the control panel before it will function in the
system. When programming this transmitter at the control,
note the following:
• Input Type = 3 (Supervised RF)
• Loop number = 1, 2, 3, or 4
• Each loop # requires one zone.
1. Install the battery (if not already installed). Observe
polarity!
2. Enter the control’s programming mode.
3. Enter the zone number to be programmed.
4. Transmit from the detector when prompted by pressing
the tamper switch.
5. When the serial number is displayed transmit from the
detector by pressing the tamper switch.
The current loop number will begin to flash.
6. Enter the desired loop number manually.
7. Test the detector after enrolling into the system. Refer
to the Testing section.

MOUNTING THE DETECTOR
You can mount the 5821 on a wall or ceiling within the
protection area:
• The 5821 may be installed in any direction.
• When used in-conjunction with the ADEMCO 470PB
probe flood sensor, use no more than 12 inches of wire
from the 5821 to the flood sensor.
• When used in-conjunction with ADEMCO T280R
temperature probe, use the shortest wire possible to
improve sensitivity.
• Although the unit can be mounted directly to a surface,
we recommend that the mounting plate be used, for
ease in removing the unit for servicing should it become
necessary.
• Avoid mounting the detector near heat generating
devices (e.g. ovens, heat vents, furnaces, boilers) or to a
metal cabinet.
IMPORTANT: This detector should be used for property
protection. Reliance should not be placed on
this detector for life safety. When life safety
is involved, smoke detectors MUST also be
used. The detector and its optional probes
must not be painted.
Wireless Transmission Path Test
A good RF transmission path must be established from the
proposed mounting location before permanently installing
the detector. To determine that there is good signal
reception from the proposed location, perform the test
procedure described in TESTING THE DETECTOR section.
Once a good RF transmission path is confirmed, mount the
detector as follows:
1. Remove the battery.
2. Disengage the attached mounting plate from the case
by inserting the blade of a small screwdriver into the
locking tab release window (see Figure 1) and pressing
it against the locking tab (also shown in Figure 1),
while sliding the mounting plate upward along the case
back until free.
3. Install the mounting plate, with its two case- holding
posts pointing up (in this example), in the location
selected. Use the flat-head screws supplied.
4. For surface wiring entry, two thin "breakout" areas are
provided in the case wall (see Figure 1).
5. Attach the case back to the mounting plate by sliding
the keyhole slots in the case back down onto the
mounting plate's case holding posts. The locking tab
will click as the case back locks in place.
EXTERNAL PROBE WIRING CONNECTIONS (If used)
6. With the battery still not inserted, connect the wires to
the unit's loop terminals (see Figure 2).
7. Install the battery.
TESTING THE DETECTOR
The test procedure should be performed to determine a good
RF transmission path and again after installation is
completed.
Activate the control panel’s test mode.
Activate the detector:
The system’s keypads should beep and the detectors ID
should be displayed.
Exit the control’s test mode.
MAINTAINING PROPER OPERATION
To maintain the detector in proper working condition, it is
important that you observe the following:
Replace the battery when the system indicates that the
5821 has reported a low battery condition.
Units should never be relocated without the advice or
assistance of the alarm service company.

TO THE INSTALLER
The mechanism may be subject to reduced sensitivity over time.
Annual testing of the operation is recommended.
Regular maintenance and inspection (at least annually) by the
installer and frequent testing by the user are vital to continuous
satisfactory operation of any alarm system.
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 components parts. Recommendations
must be included for a specific program of frequent testing (at least
weekly) to ensure the system’s proper operation at all times.
