2.3. System Description MAGIC.SENS ...LSN

Up to three detection principles are integrated into the multisensor detector

MAGIC.SENS . . . 400/410 LSN:

1. Optical (for smoke)

2. Thermal ( for heat) OTC, OC, OT, O, T

3. Chemical (for gas)

The individual sensors can be programmed via the LSN network manually or

time--controlled. All sensor signals are evaluated continually by the internal signal

analysis electronics and are linked with each other. By linking the sensors ( combined

detectors), the detector can also be used in places where the work carried out gives

rise to light smoke, steam or dust. If with the OC, OT, O, and T detectors a signal

combination fits the selected identifier for the area of operation, an alarm is triggered

automatically.

D Active self--monitoring of the sensors, with display on the fire panel:

-- Display for defined sensor faults (life--zero monitoring),

-- Stepless display of the degree of contamination (only in service),

-- Fault indication with heavy contamination (instead of false alarm).

D Active adjustment of the threshold (drift compensation) if the optical sensor

becomes contaminated.

D Active adjustment of the threshold (drift compensation) of the chemical sensor.

D T he EMVsecurity is, with 30V/m in the range 1--1000MHz and with 40V/m in the

cellular frequency ranges 415--466MHz and 890--960MHz, significantly higher than

that required by VdS 2110 (VdS Schadenverhütung GmbH).

D Thanks to integrated isolators, the LSN ring will continue to function in case of

wire breakage or short--circuit of a detector.

D Detector individual identification on the fire panel in case of alarm. Alarm

display on the detector with a blinking red LED.

D Programmable, that is, can be adjusted to the area of operation.

D Increased detection and false alarm security thanks to evaluation of the temporal

behavior of fire and disturbance variables.

D Manual or time--controlled switch--off of individual sensors for adjustment to

extreme disturbance variables.

D Activation of a remote external detector alarm display is possible.

D Va riable mechanical removal safeguard (can be activated/deactivated).

D Dust--resistant labyrinth and cap construction.

D Can be connected to the LSN – fire panel BZ 500 / universal European central unit

UEZ 2000 / universal danger detection system UGM 2020 and to other central units

or their r eceiver components with identical connection conditions.

D Depending on the central unit, using the WinPara program (Version 4.53 or higher)

it is possible to read out the serial number, degree of contamination (for the O unit),

operating hours, and current analog values for each configured detector.
