INTRODUCTION
Eaton Security Business’s DET-RSMOKE smoke detector is designed to work with Scant-
ronic 868MHz narrow band transmitters. The unit contains an integrated radio transmitter.
The DET-RSMOKE provides detection of smoke or potential fire.
It is however important to note that the DET-RSMOKE is not designed to be compliant with
the EN54 or other local statutory standards covering fire alarm systems that automatically
contact the fire services.
As an installer you should not program an intruder alarm system using a DET-RSMOKE
detector and associated system so that it is configured to replace systems that must meet
EN54 or other local statutory standards.
The DET-RSMOKE smoke detector is designed for use in family houses/apartments or
small offices rather than commercial or industrial environments. The main role of the DET-
RSMOKE is to detect smoke and provide a local alarm notification. Our smoke detector
also sends a notification to the intruder alarm system. The alarm system control unit can
then sound an alarm to notify the building’s occupants or notify personnel remotely (for ex-
ample a landlord or caretaker) using any communication device that may be fitted.
The DET-RSMOKE is suitable for use in Leisure Accommodation Vehicles (LAV’s)
The rest of this guide contains simple instructions on the approach that should be used to
ensure the positioning of the DET-RSMOKE smoke detector is optimized.

UK
Put the control unit/receiver into learn mode (consult the relevant section in the control
unit/receiver’s Installation and Programming Guide).
Radio Learning Press and hold the test button for three seconds. The detector
transmits its identity by radio (and also gives the alarm tone).
Infra-red Learning Remove the batteries. Hold the detector so that the activity LED
points at the IR learn sensor on the receiver. Make sure the activity
LED on the detector is as close as possible to the IR learn sensor.
Wait at least 60s after removing the batteries and then re-fit the
batteries. (This ensures that the DET-RSMOKE starts up correctly.)
The activity LED flashes eight times. The infra-red part of the light
carries the detector’s identity to the learn sensor.
Activity LED Control
During normal operation (when the unit is
not in alarm) the activity LED flashes once
about every minute. It is possible to disable
this feature by operating the Dip switch a)
next to the batteries, see Figure 4.

SITING
Factors Affecting Performance
The DET-RSMOKE smoke detector is designed to do three things:
• Detect smoke.
• Sound an alarm when it detects smoke.
• Send a radio message to the alarm system control unit when it detects smoke.
Each of these functions can be affected by the environment around the detector.
Detecting Smoke
The DET-RSMOKE is an optical smoke detector. This is one of the most common types of
smoke detector in use. An optical smoke detector works by admitting a continuous flow of
air to a small chamber that is shielded from all external light. Inside the chamber a lamp
shines a beam of light through the air. A light detector (photocell) to one side of the beam
looks for any light scattered by particles within the beam. The light is designed to be scat-
tered easily by small amounts of smoke entering the chamber.
All optical smoke detectors that operate in this way have the following challenges:
• They do not detect radiant heat.
• They do not detect heated air.
• Other types of particle can mimic smoke (for example dust, water droplets, insects
or steam).
• The detector cannot detect any smoke if air movement around the detector is
restricted.

The advantages of optical smoke detectors are that they are robust and
reliable, and do not need large expensive batteries.
Audible Alarm Sounder
The DET-RSMOKE uses a piezo electric sounder that produces at least 85dB(A) of sound
3m away from the detector. The volume of the alarm sound can be reduced by
distance, closed doors, heavy drapes or positioning the detector behind
furniture or other items.
Radio Signaling
The DET-RSMOKE transmits radio signals on 868.6625 MHz, a frequency within the
harmonized range in Europe for alarm signaling. The alarm signals generated by
the DET- RSMOKE are designed for Eaton’s Security Business control units and
receivers. Radio signals from the DET-RSMOKE can be absorbed and/or
reflected by metal structures, wire mesh, heat retaining window films, cabling,
metallic pipework and any other metallic items. For a detailed explanation of the
factors affecting radio transmission please read “Guidance Notes for Wireless
Alarm System Installations”, available to touchpoint members at
www.coopersecurity.co.uk under the “Support - Installation Assistance for
Wireless Systems” tab.
You must position the detector in a suitable place that does not absorb its
signals, or contains other transmitters that can interfere with those signals.
Where to Place the Detector
All the factors described above mean that there are good places to site the detector to
ensure that it will detect smoke reliably, give a clearly audible alarm, and provide a strong

10
enough signal for any receiver. All these considerations come into play in the following
recommendations:
To ensure that the detector can detect any smoke:
• Place detectors high up, in spaces where smoke accumulates.
• On flat ceilings place the detector close to the middle of the ceiling. On pitched
ceilings place the detector on the slope of the ceiling, at least one metre from the
top.
• If you cannot place a detector on a ceiling, then mount one as high as possible on a
wall, but at least 100mm away from the ceiling.
• Place detectors at the top of stair wells.
To ensure that people can hear the audible alarm:
• Place a detector on the landing outside bedrooms. The sound level of the alarm
inside the bedrooms must be enough to wake a sleeper.
• Place at least one detector on every floor of the house.
To ensure that receivers can pick up radio signals from the DET-RSMOKE:
• Place detectors high up.
• Place detectors clear of any metalwork.
• Place detectors clear of any other radio transmitter.
• Read “Guidance Notes for Wireless Alarm System Installations” carefully for more
detailed information.

Where NOT to Place the Detector
Do not place the detector in areas that smoke reaches slowly:
• Avoid ‘dead’ spaces. Dead spaces include the angle between wall and ceiling:

• Avoid ‘closed’ rooms or cupboards if you are only fitting one or a few detectors. If
you are going to fit several detectors then put one in each room where the door is
normally closed.
• Avoid spaces where there is a lot of dust. Dust may accumulate on and within the
detector, and prevent smoke reaching the sensor.

• Avoid the fresh air stream from ventilators or air conditioners. The flow
of air will blow any smoke away from the detector.
Do not place the detector in areas where there may be cause for a false alarm. Avoid:
• Spaces where there is smoke, or similar, as part of everyday life: for
example kitchens or garages.
• Central heating boilers, fireplaces, stoves, cookers, ash trays, toasters.
• Rooms with lots of water vapour/steam, for example bathrooms or
washing areas, especially where this may cause condensation on or
within the detector.
• Spaces where there may be many small insects, for example loft
spaces or greenhouses.
• Spaces where there is a lot of dust. Dust in the air may trigger the smoke detector.
• Air contaminated by solvents, for example thinners, petrol or white spirit.
• Outside areas. Smoke and contaminants can arrive from any distance if
the detector is outside of a building.

What the Detector Cannot Do
The DET-RSMOKE is designed for use in a small family home or apartment, or small of-
fice. It has the following limitations that are shared by many optical smoke detectors:
The smoke detector cannot detect a fire if smoke cannot reach the sensor. Smoke from
fire inside walls or attics, on top of roofs, or in other floors may not reach a
detector quickly enough to cause an alarm in time for the occupants to escape
unharmed. In addition, if the detector is deliberately covered to prevent smoke
reaching it then it cannot detect smoke.
The alarm sounder may not be heard. If an occupant is in another room to the
detector, is hard of hearing, is asleep, or under the influence of drugs or alcohol,
then he or she may not hear the alarm and be able to react to it.
The detector may not be able to warn about smoke from fires caused by
carelessness and general safety hazards, such as: smoking in bed, violent
explosions, escaping gas, improper storage of flammable materials,
overloaded electrical circuits, children playing with matches or arson.
No smoke detector can detect every kind of fire. In particular, smoke from slow
smoldering fires rises slowly and may not reach the detector until flame breaks
out.
PHYSICAL INSTALLATION
Use the mounting plate as a template to mark and drill two screw holes in the position
where you wish to fit the detector (see Figure 10). Note the orientation pointers molded
into the mounting plate. The two pointers are at right angles to the position of the test but-
ton on the face of the detector.

18
Fix the mounting plate into position. Mount the detector on the mounting plate by aligning
the curved rib on the base of the detector with the curved slot in the plate.
OPERATION
During normal operation the detector is silent. If the activity LED is enabled (see page 7)
then it flashes once about every minute.
If smoke is present in the atmosphere then the unit may take up to 9 seconds to detect the
smoke, go into alarm and operate its sounder. The detector sends a radio signal to the
receiver every time it goes into alarm.

If the unit’s internal circuits detect a fault then the sounder chirps once every ten seconds,
the activity flashes once a second, and the unit sends a radio signal to the receiver.
Silencing an Alarm
To silence the sounder on the smoke detector press the Test button once briefly (see Figure
3). The detector stays silenced for six minutes and then returns to normal mode. (If you carry
out an alarm test during that six minutes then the detector returns to normal mode after the
test.)
TESTING.
1. Put the control unit/receiver into walk test (follow the instructions in the relevant manual).
2. Press and hold the Test button for three seconds. (See Figure 3.) The sounder operates at
the end of the three seconds and the unit sends a radio signal to the alarm system control
unit
3. Make sure the control unit receives the alarm.
4. Choose another site for the detector if the control unit does not receive the signal.
5. Stop the walk test at the control unit/receiver.
MAINTENANCE
Every week, for example when doing the vacuuming, check that the grills are clear of debris
and test the smoke alarm by pressing the test button for at least three seconds. The alarm
signal is a penetrating, pulsating signal. The alarm sounds as long as the test button is
pressed or there is smoke in the detector. When the alarm goes off, always check carefully to
see that there is no fire and never remove the batteries from the alarm except when

20
changing them! Always test the alarm immediately after returning from holiday or after a
longer period of absence. Under the test button, there is a red activity LED. When this
LED is enabled (see page 7) it flashes about once every minute. This shows that the
batteries are correctly connected. If the alarm does not sound when testing, the batteries
must be replaced. The alarm should be dusted and cleaned regularly with a slightly damp
cloth. In connection with annual battery change or when required, for example after a false
alarm, clean and vacuum the alarm carefully using a soft brush.
CAUTION: Do not paint the alarm.
The batteries last approximately 24 months.About a month before the batteries are
completely flat, the alarm emits a short chirp once a minute. This is the signal that the
batteries need changing. The alarm works as normal during this time. The batteries
should be an alkaline 1.5 Volt AA size. Use good quality batteries: Duracell Procell
MN1500 or Eveready Energizer EN91. Always test the alarm after changing the batteries.
Notes:
1. Wait 60s between removing the old batteries and inserting the new batteries.
2. Do not pull on the catches between the batteries to try to force them out.
3. Do not try to close the battery compartment without the batteries present. The product
is designed to prevent this.
Service
If the sounder chirps once every 10 seconds and the activity LED is flashing once a sec-
ond then a fault has occurred. Remove the old batteries, wait 60s, and then fit new
batteries. Check that the activity LED is working normally.
