1. Product Description
Optical smoke detectors NOM 100/NOM K 100 work using a scattered light proce-
dure and are suitable for use in all cases where smoke is likely to form in the event
of a fire.
The detectors are particularly sensitive to white, visible smoke (e.g. smoldering fires).
With other types of smoke (e.g. open fires with smoke that is hardly visible and with
thick, black smoke), detection sensitivity is, as a result of the design, somewhat
lesser, but does always comply with the values required in line with EN 54.
The optical detector is available in two designs:
−Standard smoke detector NOM 100 LSN
and
−Smoke detector NOM K 100 LSN for use in a ventilation duct.
The smoke detectors are designed for connection in a local security network (LSN).
Depending on the application, connection takes place with other network elements
in loops or stub lines.
The power supply is provided by the two wires of the data line.

Anti−theft protection
If required, detector modules can be secured with a lock to prevent theft or
accidental movement.
Maximum number of detectors in an LSN ring
Owing to the different current consumption from the LSN data line, the maximum
number of network elements (interfaces and detectors) that can be connected must
always be observed.
The limiting values can be determined by reading the product information for the
danger detection system in question.
Installation cable
The installation cable for the NLT line must be a
J−Y(St)Y n x 2 x 0.6 or J−Y(St)Y n x 2 x 0.8 cable.
Norms, guidelines and planning recommendations
Additional norms, guidelines, and planning recommendations with respect to
installation location, monitoring area etc. must be taken into account (see fire
detector manual).

5. Device Design
The NOM 100/NOM K 100 comprises a detector module and a detector base. The
housing is made from impact−resistant ABS plastic.
The NOM K 100 is supplied with a dust filter and the appropriate mounting clamp.
The detector module contains the photo−electronic part with the light source and
the light receiver, a electronic evaluation switching, a wire mesh for insect protec-
tion in the smoke entry opening, shielding against electrical interference fields and
a silent individual display (two−color LED).
The detector base contains the contact and locking pins and the terminal clamps
for the detector line and also offers the option of connecting an external detector
alarm display.
The detector module is engaged in the detector base by slotting it in and turning it.
Several detector base versions are available for NOM 100.
There is a special ventilation duct base for the NOM K 100.

6. Functional Description
Smoke and contamination are measured separately with the NOM 100/NOM K 100.
For smoke measurement, a light source sends 15 light flashes through the mea-
suring area one after the other at one second intervals.
For contamination measurement, an additional light source then sends a light
flash to the opposite interior wall.
In both cases, the light, which contacts a photo diode, provides information about
quiescent state, contamination or alarm.
