Product description / Function
The DKM communicates with the STG via the safety-monitored
system ringbus. The detectors forward fault and alarm mes-
sages to the STG and indicated on a display. A technician or
building manager can therefore see all connected detectors at a
glance. Important .
Note: Please also note separate specication sheets for STG 1.2.
The manual call point consists of the plastic housing and door.
It contains the circuit board with terminals, trigger mechanism,
and push-button. The replaceable standardized thin glass
pane in a lockable door (protected by a standardized lock) is
a safeguard against unintended triggering. In the event of an
alarm, the glass pane is easily broken and the pushbutton can
be pressed without interference. A special retainer keeps the
button in the pressed position. The manually actuated retainer
lever is used to release the push button. The particularly low-
prole conguration of the manual call point eliminates the
need for in-wall installation.
The detector has cable connection terminals on top and on the
bottom. An opening can be punched out on the rear face of
the detector for installation on an in-wall cup. In the event of
an alarm, the glass pane (2) is punched in rst, and the push-
button (3) is then pressed deeply. This actuates the micro-
switch to trigger the alarm; display LED (4) lights up. A locking
mechanism retains the engaged push-button. The engaged
push-button is reset by manually actuating the reset lever (5) or
by opening the detector door (1). The alarm is reset and the LED
(4) goes dark. The alarm must also be reset on the STG.

Installation instructions
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.
Other instructions:
• Manual detectors must be installed in a readily visible locations
along escape and emergency routes (e.g. exits, entryways,
stairwells) and must be readily accessible.
• The installation height of 1400 mm ± 200 mm, measured from
center of the push-button to the oor must be observed.
• Manual detectors must be suciently illuminated by daylight
or an alternative light source (including emergency lighting, if
applicable).
• Pursuant to VdS guidelines, a maximum of 10 non-automatic
re detectors can be connected to a primary cable. The test
detector can be used on primary cables together with auto-
matic re detectors. It is connected at the electrical end of the
primary cable (max. 1 test detector per primary cable).
• The distance between non-automatic re detectors should be no
more than 100 meters iaw. DIN 14 675, and 80 meters iaw. VdS.
• Non-automatic re detectors should be separated by a
maximum distance of 40 m (VDE 0833 Part 2, Section 7.2.6) in
particularly high-risk zones.
• Other standards, guidelines, and project planning recommen-
dations regarding installation location, etc. must be taken into
account where appropriate (see re detector manual).
• Local re department regulations must be observed.

Electrical connection
All work on electrical installations or equipment must only be performed by a trained electrician or by an instructed person under
the direction and supervision of a trained electrician in accordance with electrical engineering principles.
The maximum bus length is 250 m (loop length 500 m).
Each connected detector must be assigned a dedicated,
unique BUS address between 1 and 99. This is accomplished
with the PG 3.3 programming tool (accessory) The assigned
default address is 1. On request, Oppermann can congure the
detectors with custom BUS addresses (indicate in your order).
The positioning of addressed DKMs in the ringbus is arbitrary. A
fault alarm is triggered if the same detector address is assigned
twice on the ringbus. If the detector address is changed, the
detector must be reregistered with the STG in service mode.
