Product Information MAGIC.SENS -- Product range
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)
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.
2.3.1. Features MAGIC.SENS . . . LSN
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 The 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 Variable 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 receiver 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.
