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 specification 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-
profile configuration 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 first, 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.
