DET8M Wireless Temperature/Flood Sensor - Installation Instructions
OVERVIEW
The Honeywell DET8M Temperature and Flood sensor is a wireless
transmitter used with Honeywell's alarm systems that support 868 MHz
devices.
The versatile DET8M can be set up in several different configurations:
Possible Configurations
HOT COLD External
(on board) (on board) Sensor*
Set the DET8M configuration with the accessible DIP switches and
potentiometers. Refer to the illustrations on page 1 and the tables in Step 2
to set the operating mode.
1
SELECT MOUNTING LOCATION
• The DET8M can be mounted on walls or ceilings, in any direction, in a
room where temperature ranges from -10° to 55° C.
• Ensure that there is adequate space around the mounting bracket (in all
directions) to slide transmitter body onto the bracket (see D).
• To monitor room temperature (cold or hot) mount the sensor within the
room to be monitored.
• To monitor refrigerator or freezer temperature, use a T280R temperature
probe (not included). Mount the DET8M on the room wall or ceiling, and
the T280R inside the Refrigerator or Freezer.
• For flood detection, use FP280 Flood Probes. Up to 4 can be used (in
parallel). One is included with the DET8M.
− The flood probes should be mounted as close as possible to the
potential flood source, and at the lowest level.
− The FP280 can be mounted either vertically or flat on the ground.
(See E on page 1.)
• Flood or Temperature probes must be mounted within 5 meters (wire
length) of the detector.
• For intrusion detection, use a device with a normally closed contact that
does not require power, such as a magnetic contact. If using more than
one contact, connect them in series. Maximum total combined cable
length must not exceed 100 meters. One 10K resistor must be used in
the loop.

SET SENSOR CONFIGURATION AND OPERATING MODE
Configure the DET8M with the on-board potentiometers and DIP switches.
See B on page 1 and the following tables to set the operating mode.

Note: If no external
sensors are used, set
Switch 5 ON and
Switches 3 & 4 OFF
Alarm d (REFRIG.) ON
Alarm c (FREEZER) ON
Alarm b (HOT) ON
Alarm a (COLD) ON
Note: After any DIP switch change, reset the power.
Switches 1 - 5, plus the potentiometers (a – d) configure the detector for
temperature sensing.
− The sensor will signal an alarm when the temperature drops below the COLD
potentiometer temperature setting for approximately 10-30 minutes.
− The sensor will signal an alarm if the temperature rises above the HOT
potentiometer temperature setting for approximately 10-30 minutes.
*External sensor types
include: one T280R
Temperature Probe (to
monitor either a Refrigerator
or Freezer), or FP280 Flood
Probes (up to four in parallel),
or intrusion detectors
(magnetic contacts, in series).

4 Alarm d (REFRIG.) OFF
3 Alarm c (FREEZER) OFF
2 Alarm b (HOT) OFF
1 Alarm a (COLD) OFF
− To monitor a freezer or refrigerator, use a T280R Remote Temperature
Sensor. The sensor will signal an alarm when the temperature rises
above the FREEZER or REFRIGERATOR potentiometer temperature
setting for approximately 10-30 minutes. (Switch 5 must be ON.)
− When the flood probe(s) detect water (see E), the sensor will signal an
alarm within 60 seconds.
− The sensor will signal an alarm as soon as a tamper or intrusion is
detected.
Switch 6 sets the protocol.

INSTALL THE BATTERY
One 3 Volt Lithium battery powers the DET8M. (See Specifications, page
8.)
Open the sensor and remove the battery pull-tab (see A & B on page 1).
If the battery voltage gets too low, the DET8M sends a low battery signal to
the control panel.
4
VERIFY RF TRANSMISSION / REGISTER THE SENSOR TO THE
PANEL
Ensure a good RF transmission path from the proposed mounting location
is established before permanently installing the detector. To determine that
there is good signal reception from the proposed location:
1. Activate the control panel's programming mode and register the sensor.
Refer to the control panel's manual and the programming tool manual for
information on registering wireless devices.
2. Activate the detector by removing and replacing the cover. The system's
keypads should beep and each zone that the DET8M is programmed for
will be displayed.
3. Exit the control panel's programming mode.
Tamper Protection: The DET8M tamper protection feature causes a
tamper signal to be sent to the control panel if either the unit's cover is
removed, the DET8M is removed from the mounting bracket, or an external
probe is used and the wire is cut. The tamper is also used to program the
unit's serial number and loop assignment to the control panel.

MOUNT THE SENSOR
• Secure the mounting bracket to the wall using the three screws provided
(see C).
• For surface wiring entry, a thin "breakout" area is provided in the sensors
back cover. (See B.)
• Attach the sensor to the mounting plate (See C & D). Slide the keyhole
slots in the back cover down onto the mounting plate holding posts. The
locking tab will click as the sensor locks into place.
T280R External Temperature Probe
• Ensure that the battery is removed from the transmitter prior to hooking
up the probe to the transmitter.
• Before connecting the probe to the DET8M, measure the resistance.
Resistance should be 70 KŸ – 130 KŸ at room temperature (22° C – 29° C).
Warm the T280R in your hand for 60 seconds to verify the resistance
drops.
• Insert the leads of the remote probe into the terminal block and tighten
the screws. The terminals are not polarity sensitive.
FP280 Flood Probes
• The flood sensor must be mounted on a clean, dry surface. Remove the
double sided tape outer skin and stick the sensor to the wall or floor.
Where mounting surface is appropriate, use a number 6 screw
(provided) to secure the flood probe.
• The FP280 has a built in 2.2MŸ resistor. After mounting, measure to
verify 2.2MŸ resistance before connecting each probe to the DET8M.
• Insert the leads of the remote probe into the terminal block and tighten
the screws. The terminals are not polarity sensitive.
• After a flood condition, the unit will restore within one minute after water
recedes from the probe.
Important:
The DET8M should be used for property protection only, and not
relied upon for life safety.
