5 Installation
5.1 Safety instructions
 Please observe the valid regulations for installation in
the country in which the smoke alarm is installed and
operated, and the national regulations for accident
prevention. Please also observe any internal company
regulations, such as work, operating and safety regu-
lations.
 The technical specifications and limit values stated
must not be exceeded under any circumstances. In
particular, this applies to the specified ambient tem-
perature range and IP protection category.
 If a higher IP protection category is required for a spe-
cial application, the smoke alarm must be installed in
an appropriate housing or in an appropriate enclosure
with the required IP protection category.
5.2 Siting location requirements
To ensure proper functioning of the unit, the conditions
for the installation site of the unit specified in section 8
"Technical specifications" must be observed.
Electromagnetic interference
– Interfering electrical installations (high frequency)
should be avoided.
5.3 Installation procedure
5.3.1 Notes on assembly
 It is vital to ensure that the smoke alarm is always as-
sembled with the sensor head pointing downwards.
In any other position, there is no guarantee that smoke
will be detected.
 The smoke alarm must also be positioned so that it is
ventilated with an adequate amount of air and the ven-
tilation slots are not covered.
5.3.2 Installation with the mounting plate
provided
The smoke alarm is installed using the mounting plate
provided.
 Release the smoke alarm sensor head from the base.
To do so, hold the base, twist the sensor head, and
pull it off the base in a downward direction.
Fig. 2: Installing the smoke alarm
 Attach the base to the mounting plate using the M4 x
18 screws provided.
 Replace the sensor head onto the base and secure it
by twisting until it locks home.
 Secure the mounting plate to the enclosure frame with
the sensor head pointing downwards using the M6 x
16 screws or clamps.
5.4 Connecting the smoke alarm
The CAN bus connection supplies the smoke alarm with
the necessary operating voltage. There is no need to
connect a separate power supply unit.
Fig. 3: Rear of the smoke alarm
Key
1 CAN bus connection, 24 V
2 CAN bus connection, 24 V

Use a CAN bus connection cable to connect the
smoke alarm to a CAN bus interface on the
CMC III Processing Unit or the neighbouring compo-
nent on the CAN bus (fig. 3, item 1).
The following CAN bus connection cables from the
CMC III accessories range may be used:
– 7030.090 (length 0.5 m)
– 7030.091 (length 1 m)
– 7030.092 (length 1.5 m)
– 7030.093 (length 2 m)
Note:
If the housing of the CMC III smoke alarm is
opened, please be very careful not to touch
the circuit board of the smoke alarm with
your hands, as this may damage the sensor.

The smoke alarm software is updated, if necessary, after
connection. The status LED of the smoke alarm glows
blue throughout and also flashes purple during the entire
update process.
In addition, the status LED of the CMC III Processing
Unit flashes white and a corresponding message ap-
pears on the website.
The smoke alarm update is complete when the following
conditions have been fulfilled:
1. The LEDs on the CAN bus connection of the smoke
alarm show green.
2. The multi-LED of the smoke alarm flashes blue and
also green or red, depending on the status of the
smoke alarm.
Further components are connected as a daisy chain.
 If necessary, connect another component (e.g. anoth-
er sensor type) to the second, free CAN bus interface
of the smoke alarm (fig. 3, item 2).
Status change display:
– The two green and the two red CAN bus LEDs on
the CAN bus connection flash.
– The multi-LED of the Processing Unit flashes contin-
ually in the sequence green – yellow – red.
– The multi-LED of the smoke alarm flashes blue con-
tinuously.
– Press the "C" key on the CMC III Processing Unit (an
initial audio signal will sound) and keep it pressed for
approx. 3 seconds until a second audio signal is
heard.
Status change display on the CAN bus LEDs
– Continuous green LEDs: CAN bus status "OK".
– Continuous red LEDs: CAN bus status defective.
Status change display on the multi-LED of the Pro-
cessing Unit
– Continuous green light: All devices connected to the
CAN bus have the status "OK".
– Continuous orange light: At least one device connect-
ed to the CAN bus has the status "Warning".
– Continuous red light: At least one device connected to
the CAN bus has the status "Alarm".
Status change display on the multi-LED of the
smoke alarm
– Continuous blue flashing: Communication via the CAN
bus.
– Green flashing: When the measured value changes, or
at least every 5 seconds.
Note:
No settings can be modified as long as the
update process is running.

6.3 LED displays
A multi-LED for the status display is integrated into the
rear of the smoke alarm.
6.3.1 Multi-LED displays
The status of the smoke alarm can be read on the multi-
LED.
6.3.2 LED displays on the CAN bus connection
A red and a green LED are located on the CAN bus con-
nection. They display the status of the CAN bus.
6.4 Operation
Once the smoke alarm has been tripped, it will need to
be reset. This requires the following actions:
 First, allow the smoke to dissipate completely, to avoid
re-activating the smoke alarm.
 Disconnect the power supply to the sensor head by
releasing it from the base (twist and then pull off down-
wards).
 Wait for at least one second, then push the sensor
head back onto the base and lock it into position by
twisting.
6.5 Operating via the CMC III Processing
Unit website
After logging on to the CMC III Processing Unit, the web
interface for operating the device is displayed.
 First select the "CMCIII-SMK" entry in the navigation
area.
Similar to the CMC III Processing Unit, the Configuration
tab can be used to individually configure the access
rights for the smoke alarm (Device Rights button) and
the alarm messages (Alarm Configuration button).
The Observation tab is used to configure all of the set-
tings for the smoke alarm, such as the time delay for
changing the status message.
In the following sections 6.5.1 "Device" to 6.5.2
"Smoke", only those parameters which you can modify
are described. There are also display values that provide
information.
6.5.1 Device
General settings for the smoke alarm are configured at

7.1 Storage
If the device is not used for a long period, Rittal recom-
mends that it be disconnected from the mains power
supply and protected from damp and dust.
7.2 Disposal
Since the smoke alarm consists mainly of the "housing"
and "circuit board" parts, the device must be passed on
to the electronic waste recycling system for disposal.
