Product description/functionality
The DRM communicates with the STG control unit via the safety-
monitored system ringbus. The alarms forward fault and alarm
messages to the STG and indicated on a display. A technician or
building manager can therefore see all connected alarms at a
glance. The system ringbus monitors for short-circuits and broken
cables. An alarm or fault message is indicated on the STG in each
case. Messages must be manually reset on the STG after the fault
has been lifted (not self-canceling).
The optical alarm (scattered light eect) provides early warning
for incipient res with smoke, in particular smoldering res. The
sensor cavity houses a dual infrared light source with 360° detec-
tion. Normally, the pulsating light ray from the transmitter does
not reach the receiver. If smoke particles enter the sensor cavity,
a portion of the light is reected to the receiver resulting in an
alarm trigger. Two red LEDs on the RM 3.3 smoke alarm and one
red LED on the STG 1.2 indicate an alarm.
The alarm status on the RM 3.3 smoke alarm expires automati-
cally after the alarm cavity is free (LEDs on RM go dark). The alarm
remains intact on the STG until it is manually reset at the control
unit. The STG can only be reset when the alarm LEDs in the smoke
alarm have gone dark.
Starting at a contamination level of 70 %, the STG 1.2 indicates
a message to prompt targeted maintenance. An alarm is issued
starting at 99% contamination.
Important note: Please also note separate specication sheets
for STG 1.2.

Installation
All work must only be performed by suciently qualied trades-
men. The respectively applicable local rules and regulations (e.g.
national building codes, electrical/VDE regulations, etc.) must be
observed. Installers and operating entities are required to su-
ciently familiarize themselves before startup. We are not liable
for printing errors and changes after printing. Appropriate use
implies compliance with operating and installation instructions.
We are not liable for losses due to inappropriate use. Unautho-
rized or inappropriate manipulations or modications of the
device render the operating permit, the product warranty and
warranty claims null and void.
Startup and maintenance/test
The alarm must be tested after installation and at least once
annually with suitable test spray (e.g. Oppermann RDP 300). The
red LED on the smoke alarm must indicate; the control unit must
switch to„Alarm“ and lock out. The unit is unlocked with the reset
button provided the smoke alarm cavity is free.
The ceiling smoke alarm consists of the smoke alarm socket RMS
3.3 and the smoke alarm RM 3.3. The alarm is mounted to the
socket with a bayonet lock and facilitates straightforward opera-
tion of the alarm. The smoke alarm RM 3.3 is engaged to the socket
in clockwise direction. Note the lateral mark for this purpose. Align
the smoke alarm approximately 15° before the socket mark and
then rotate in clockwise direction. The smoke alarm is disengaged
in counter-clockwise direction. We recommend gripping the socket
rmly and taking care to avoid misalignment between the two
parts. The socket is installed in an appropriate location with dowels
and screws.The cable is routed through the center.

Alarms are supplied with power from the system ringbus. The bus cable must be shielded on both sides (terminal 7).
The maximum bus length is 250 m (loop length 500 m).
Smoke alarm address
Each connected alarm must be assigned a dedicated, unique BUS address between 1 and 99. This is accomplished with the PG 3.3
programming tool (accessory) The standard default address is 127 and is therefore not recognized by the STG. On request, Opper-
mann can congure the alarms with custom BUS addresses (indicate in your order - particularly important when ordering replace-
ment parts). A fault alarm is triggered if the same alarm address is assigned twice on the ringbus. If the alarm message is changed,
the alarm must be reregistered with the STG in service mode. The positioning of addressed DKMs in the ringbus is arbitrary.

Programming:
• Disconnect smoke alarm RM 3.3 from smoke alarm socket.
• Engage smoke alarm RM 3.3 onto the bayonet lock of the programming tool (rotate in clockwise direction). Align exterior mark on

• Switch on programming tool by pressing the left gray button. The address is read from the alarm and shown in the display.
• Change address with the two gray buttons. Dots blink behind the gures while the address is being changed.
• Save address with the red button. The blinking dots behind the gures vanish.
