2. Prescribed use
The ‘RM 100-2 Uni-S’ smoke detector registers smoke emissions (smouldering fire and open
fires with smoke emissions) and sets off an alarm when the smoke concentration reaches a
certain level.
The alarm is carried out via the integrated signal transmitter and a red warning LED. A bright,
white LED is also activated as an emergency light.
The smoke alarm is simultaneously radio-transmitted to the ‘HMS 100 Z’ central unit of the
‘HMS 100’ hazard detection system or the ‘FHZ 1000’ home radio central unit. This ensures
that a fire, which is some distance away (on another floor of the house, for example), can be
responded to in good time.
A smoke alarm can also be relayed by cable when several smoke detectors of this type are
connected by cable. This allows rooms to be monitored whose current conditions make radio
monitoring technically difficult.
For further information please see section 7.
The radio smoke detector should not be used in environments such as hospitals with life-
support systems or other similar environments in which the transmission of radio signals may
cause devices to malfunction.
Batteries must be used to power the smoke detector.
The product should only be installed and operated in dry indoor locations. Make sure it does
not get damp or wet.
No part of the device may be modified or adapted. Doing so invalidates the licence (CE) and
the guarantee/warrantee.
The manufacturer does not assume liability for damages caused by the improper use of the
device. All guarantees and guarantee claims will be invalidated in such cases.
The device may only be operated when its casing is fully closed.

6. Notes on batteries and rechargeable batteries
For safety reasons, the smoke detector should not be operated using recharge-
able batteries.
Due to the its low voltage (rechargeable battery = 1.2V, battery = 1.5V) the
smoke alarm may perceive that the rechargeable battery is low even though it
is fully charged. It then emits a soft signal tone every 48 seconds and the red
LED blinks three times every 48 seconds.
Therefore, please make sure that you only use high-quality alkaline batteries
(Conrad item no. 650117, for example. Order 3 batteries).
• Keep batteries (and rechargeable batteries) out of the reach of children.
• Make sure that the polarity is correct when inserting the batteries.
• Do not leave batteries/rechargeable batteries lying around as they could be swallowed by
children or pets. In such case seek immediate medical care.
• Leaking or damaged batteries/rechargeable batteries may cause acid burns, if they come
into contact with skin. Therefore, please make sure you use suitable protective gloves.
• Make sure that batteries/rechargeable batteries are not short-circuited, taken apart or
thrown into fire. They might explode!
• Conventional batteries must not be recharged. They might explode!
• If the device is not used for a longer period of time (when stored, for example), remove the
inserted batteries. This way, you can prevent the aging batteries from leaking and causing
damage.
For safety reasons, the device’s casing cannot be locked, if no batteries
have been inserted!

7. Features and functions
The ‘RM 100-2 Uni-S’ smoke detector registers smoke emissions (smouldering fires and open
fires with smoke emissions) optically using the scattered light principle.
When the smoke concentration reaches a specific level, the smoke detector activates the
integrated signal transmitter. A red warning LED is also activated as well as a white LED, which
serves as an emergency light.
A smoke alarm is simultaneously transmitted to an existing ‘HMS 100 Z’ central unit belonging
to the ‘HMS 100’ hazard detection system or the ‘FHZ 1000’ home radio central unit.
This ensures that a fire, which is some distance away (on another floor of the
house, for example), can be responded to in good time.
Furthermore, several smoke detectors in the ‘RM 100’ series can be connected by cable,
allowing the smoke alarm to be relayed by cable.
This allows rooms to be monitored whose current conditions make radio
monitoring technically difficult.
In order to avoid crossovers with other radio services operating on the 868 MHz frequency
band, the system can be coded using a house code. This protects the system from false alarms
caused by other radio transmitters operating in the same frequency range.

8. Selecting the installation location
Wegenerallyrecommendthatseveralsmoke
detectors be installed in a building or an
apartment. One smoke detector should defi-
nitely be installed on each floor of a multi-
storey building. This is the only way to en-
sure that an effective warning is issued in
time when a fire starts.
Smoke detectors should be installed in such
a way that they safeguard a route to the
bedroom (entrance area, hall or stairway).
And, when an alarm sounds, they must also
be audible through a closed bedroom door.
The smoke detector should always be
mounted to the centre of a room’s ceiling.

Study Living
room Children’s
room
Entrance area Kitchen
Minimal protection
Recommended protection
When installed in an attic room with a pointed roof, the smoke detector should
not be attached to the highest point of the room as here there is hardly any
movement of air. An ideal installation location would be a roof beam or an
overhang beam.
Smoke
Air pockets that keep the rising smoke away collect close to the walls, and also in the corners
of rooms and where there are sharp-angled ceilings. This makes the smoke detector take a
lot longer to detect smoke and trigger its alarm.

11
In normal rooms, the smoke detec-
tor should be installed at least 60
cm away from the corners of the
room.
Radiators, window sills, windows
and even furniture affect the circu-
lation of air.
Ideally you should mount it to the
ceiling in the centre of the room.
60cm60cm

Smoke
If you select an unsuitable installation location the smoke detector will remain
more or less useless when a fire starts; only triggering an alarm when the
smoke concentration reaches a very high level.
This will significantly reduce the amount of time available for saving yourself
and others from danger or for extinguishing the fire.
Window sills, curtains or furniture strongly influence the circulation of air, and
thus, the movement of smoke. They create a zone of dormant air. This means
that rising smoke does not reach the smoke detector or it reaches it too late!
We generally recommend that the smoke detector be mounted to the ceiling in
the centre of a room. However, you should make sure that you do not install the
device directly under any lights (halogen lamps, for example).
You can check whether the alarm is sufficiently loud enough to wake someone up from its
installation location by setting off a test alarm (see ‘Installation’) while someone is asleep in
the bedroom.
The smoke detector should be loud enough to wake people up! It should
not just be audible!
You should also carry out extensive checks to make sure that the radio signals sent by each
of the smoke detectors from their installation locations will reach the ‘HMS 100 Z’ or ‘FHZ 1000’
central unit.
In general, reception problems are not experienced in most single family
houses. As you can see in section 15 (‘Information on the radio range’),
however, many things can restrict the radio reception.

12
For example, reinforced concrete ceilings or electric floor-heating systems can
hinder reception between several floors.
Electric cables, electric devices or metal objects can also reduce the range.
It can be difficult to install the smoke detector in the following rooms and locations:
•Kitchen/bathroom: False alarms due to kitchen steam or high levels of humidity
•Garages: False alarms due to exhaust gases from cars, motorcycles or other combustion
engines
•Living rooms with an open fireplace: False alarms due to escaping smoke
•Dusty and dirty rooms: Dirt on the measurement chamber causes the smoke detector to
become less sensitive so that the alarm is activated later or not at all
•Places with a strong movement of air: Late smoke detection and alarm due to the
proximity of windows, fans, lamps, lamp tubes, halogen transformers, radiators, fireplaces
•Proximity to metal/electric devices: Deterioration of the radio range due to steel beams,
large metal surfaces, metal doors, televisions, power cables and so on
•Smoke from tobacco: False alarms as the smoke detector cannot differentiate between
‘harmless’ tobacco smoke and a real fire
Some smoke detectors have a sensitivity setting. The disadvantage of this,
however, is that the alarm is triggered late when a ‘real’ fire occurs, and this
shortens the response time considerably. The time that is available for
extinguishing the fire, for saving people or for escaping is considerably
reduced!

9. Installation
Please make sure you read the information on selecting an installation location
provided in section 8.
• Remove the smoke detector’s upper plate by carefully twisting the upper plate and the lower
plate against each other (anticlockwise).
The upper and lower plates can only be locked firmly, once the batteries have
been inserted.

BC
A Mounting holes for installation using an
installation box
B Holder for cable ties
C Alternative installation using spacers
• You can use the two mounting holes to screw the lower plate securely to a wall or a ceiling,
for example.
Depending on the type of surface, you may have to first drill two mounting holes and insert
suitable dowels.
When drilling or screwing be careful not to accidentally damage any
power supply lines, gas or water pipes. Life-threatening danger!
• Alternatively, the lower plate can be mounted using the two spacers (if cables run under the
smoke detector, for example) or via the screws of an installation box.

10. Initial operation
Initial operation varies for the two ‘HMS 100’ and ‘FHZ 1000’ systems. Please
make sure you read the following subsections.
a) Setting the house code for the smoke detector
You only need to set this house code, if the smoke detector is operated as part
of the ‘FHZ 1000’ system!
House code RM100-2 Uni-S FHZ1000
Code on
the display
Use the DIP switches 1 to 4 to set a
house code (freely selectable between
0 and 15).
The samecode must also be set for the
‘FHZ 1000’.
This code stops neighbouring radio
smoke detectors from triggering unin-
tentional alarms on the ‘FHZ 1000’.

15
b) Setting the house code for the ‘FHZ 1000’
You only need to set this house code, if the smoke detector is operated as part
of the ‘FHZ 1000’ system!
Proceed as follows:
• Press the ‘x’ button on the ‘FHZ 1000’.
• Turn the scroller on the ‘FHZ 1000’ until ‘Sonderfkt.Sonderfkt.
Sonderfkt.Sonderfkt.
Sonderfkt.’ appears on the display.
• Keep the ‘PROG’ button pressed until ‘Ext. AlarmExt. Alarm
Ext. AlarmExt. Alarm
Ext. Alarm’ appears on the display of the ‘FHZ
1000’.
• Use the scroller to set the house code that you previously set for the ‘RM 100-2 Uni-S’
smoke detectors.
• Press the ‘PROG’ button. The setting is applied and the menu closes.
• It is not necessary to separately register the smoke detector to the ‘FHZ 1000’. Only the
alarm priority may still need to be set up according to the FHZ 1000’s user manual.

16
c) Switching the ‘HMS 100’ function on and off
The ‘RM 100-2 Uni-S’ radio smoke detectors transmit a status signal every 30 minutes
(including, amongst other things, the battery level) to the ‘HMS 100 Z’ central unit.
DIP switch 5 must be in the ‘ON’ position for this function to work.

ON DIP
‘HMS 100’ function on
If you do not intend to operate the smoke detector as part of the ‘HMS 100’ system, you can
use DIP switch 5 to switch off the ‘HMS 100’ radio protocol.
This extends the battery life.

• Now insert the batteries into the smoke detector, as described in section 10 e).
• Then complete the registration. See section 10 f).

18
e) Inserting the batteries into the smoke detector
• Have you already set the ‘HMS 100 Z’ to the sensor search mode?
If you have not done so already, remove the batteries and first follow the instructions
provided on the previous page in section 10 d).
• Insert three new AA batteries (LR06, Conrad item no. 650117, for example) into the three
battery holders, making sure that the polarity is correct. Useful figures are located in the
battery compartments.
As described in chapter 6, we recommend that you use high-quality alkaline
batteries.
• Once the batteries have been inserted, the red control indicator blinks approx. every 48
seconds to signal that the smoke detector is ready to be used.

f) Completing the sensor search on the ‘HMS 100 Z’
You only need to set this, if the smoke detector is operated as part of the
‘HMS 100’ system!
• Once the central unit has received the signal from the radio smoke detector, ‘Sensor xxSensor xx
Sensor xxSensor xx
Sensor xx’
(xx = 01-30) appears on the display. The smoke alarm symbol is also displayed.
A cursor appears on the lower display line (entry bar). Here you can enter a name for the
smoke detector in plain text that is up 11 positions long.
• Use the ‘x’ and ‘w’ buttons to select the desired entry position (this also allows you to enter
space characters) and use the scroller to set the character you require (alphabet, umlauts,
digits, space characters) at the cursor position.
• Then select the next position using the ‘x’ and ‘w’ buttons and repeat the procedure until
you have entered the complete name.
You can also use the ‘x’ and ‘w’ buttons and the scroller to subsequently modify the text
you have entered.
You can also delete characters that have been entered using the space character (after ‘9’
or before ‘A’). You can delete the whole name all at once using the ‘Löschen’ button
(= ‘Delete’).
• Once you have entered the name, press ‘OK’.
g) Locking the smoke detector into its socket
Insert the smoke detector into the mounted lower plate by turning it clockwise. The red triangles
fitted in the lower plate and in the smoke detector help you to position it correctly.
Please note:
For safety reasons, the two parts of the casing (lower plate/smoke
detector) cannot be locked, if no batteries have been inserted!

11. Function control and operation
a) Control panel & function test
• After mounting the smoke detector you should carry out a function test.

A Opening for acoustic signal trans-
mitter
B Test button with LED indicator
C Optical signal transmitter (emer-
gency light) lights up together with
the acoustic signal transmitter
• Blow tobacco smoke, for example, onto the smoke detector. Once the smoke has
penetrated the smoke chamber inside the smoke detector, the alarm is activated, so long
as smoke is still located in the smoke detector’s smoke chamber.
A triggered alarm is signalised by an acoustic and an optical signal (about every second).
• The alarm is automatically terminated after 48 seconds once the smoke alarm’s electronics
in the smoke chamber no longer detect any smoke.
• The red control indicator of the triggering smoke alarm continues to blink for about ten
minutes after the alarm has terminated. This makes it easier to find the triggering alarm
when there is a false alarm, for example.
• Pressing the test button for approx. 2 seconds (press the button up to the pressure point)
causes the acoustic alarm to stop for approx. 10 minutes.
If there is still smoke in the smoke chamber, the LED continues to blink. Otherwise the alarm
stops completely.
