3. Planning Notes

MAGIC.SENS fire detectors are not intended for

external use!

3.1. Basic Planning Specifications

D T he planning of multisensor fire detectors (combination detectors) occurs

according to the guidelines for optical detectors until an independent guideline has

been worked out with the VdS.

D The types OTC, OC and OT are planned according to the guidelines for optical

detectors if they are operated as optical detectors or combined detectors; see

DIN VDE 0833 Part 2 and VDS 2095,

-- maximum m onitoring area 120m

-- installation height up to 16m.

D If the occasional switching--off of the optical unit (scattered light sensor) is

desired, the planning must occur according to the guidelines for h eat detectors;

see DIN VDE 0833 Part 2 and VDS 2095,

-- minimum monitoring area 40m

-- installation height maximum 7.5m for the T 400 E LSN or OT 400 E LSN

-- installation height maximum 6m for the T 300 GLT or OT 300 GLT.

D Maximum cable length: 1000m, for J --Y(St) Y n x 2 x 0.6 / 0.8.

D Maximum permissible air speed: 20

D When planning for fire barriers according to DIBt, the following m ust be taken

into account:

-- T 400 E LSN must be programmed according to class A1R,

-- the characteristic curve of the T 300 / F SA also corresponds to the A1R class.

3.2. Use on a Local Security Network (LSN)

On the LSN, up to 127 detectors can be operated in the following operating modes

depending on the loop or stub:

Operating mode

Detector type combined only opti cal only therm o--maximum only thermo --differential

OTC 410 LSN x x x x

OC 410 LSN x x -- --

OT 400 E LSN x x x x

O 400 E LSN -- x -- --

T 400 E L SN -- -- x x

3.3. Use with Conventional Line Technology

(German: Gleichstrom Linientechnik, abbreviated (GLT)

The GLT technology permits the connection of up to detectors to a primary line.
