4. Programming

Programming is setting a LSN detector to the desired operating mode.

Pro

gramming is carried out with the >WinPara< software using a PC or laptop connected

to t

he fire panel.

All sensor signals are analyzed continually by the internal evaluation electronics and

are linked with each other via an inbuilt microprocessor.

The d

etectors OTC 410 LSN OC 410 LSN and OT 400 E LSN are programmed by

specifying the o

peration location (e.g. computer room, office, large kitchen).

The sele

ction of the operation location determines the optimal characteristic diagram

for fire a

nd disturbance variable evaluation.

With low sensitivity of the o

ptical sensor in the OTC 410 LSN, the detector only triggers

if s

moke and also an increase of the CO concentration or the temperature is detected.

With the ty

pes OTC 410 LSN and OT 400 E LSN, the operating mode can be changed.

at is, individual sensors can be switched off:

-- Sw

itch to optical (sensitivity O unit = low, T unit = switched off)

-- Sw

itchover to thermo--differential (sensitivity T unit = A2R, O unit = switched off)

-- Sw

itchover to thermo--maximum (sensitivity T unit = A2S, O unit = switched off)

With p

urely optical detectors O 400 E LSN, the sensitivity of the optical sensors can

be s

et on 3 levels. Depending on the operation location, the optical sensor in the

detector is th

us adjusted to the environmental conditions.

For fire re

cognition, the optical detector uses the temporal behavior of the fire variables

that deviates significantly from the temporal behavior of disturbance variables and

also f

rom the time behavior of a detector test with aerosol. Depending on the sensitivity

set, t

herefore there are also different trigger times when testing with a test aerosol,

outside of main

tenance operation (10s to max 60s).

The thermal detector T 400 E LSN is programmed by taking into account the ambient

temperature a

nd installation height with the selection of the sensitivity class.

Pro

gramming of the optical, thermal, and chemical detector and the linking of all detectors

via al

gorithms significantly increases the detection ability and security against false alarms.
