CONCENTO PLUS - <strong>Technical</strong> <strong>Manual</strong>, 11/12 (Rev. 3.0), 00 8814 14<br />
- Unambiguous call raising and simple handling must be ensu‐<br />
red for the changing users, and the possibility of mix-ups with<br />
parts of other systems must be eliminated.<br />
- Damage or destruction by external influences that can be ex‐<br />
pected during proper use (e.g. bed transport) must be impossi‐<br />
ble.<br />
- May not be installed in rooms that can have harmful effects on<br />
telecommunications systems.<br />
Devices with displays - Must be well within the field of vision (terminals, display mo‐<br />
dule).<br />
- Should not be subjected to direct sunlight<br />
Call switches, call devices - Must be in easy reach.<br />
Presence buttons - Near doors<br />
Visual signalling devices - Recognition must not be impaired by light from other sources.<br />
Signal lamps, corridor displays - Must guide the called or sought persons to the call location via<br />
the shortest route.<br />
Room lamps - Must be easily assignable to the rooms.<br />
In WCs and wet rooms - Observe the special regulations of DIN VDE 0100!<br />
Power supply units, Group<br />
Electronics, Management<br />
Interface, fire alarm interface<br />
Distribution boxes that are<br />
used jointly for the nurse call<br />
system and power system<br />
- Only in dry rooms, ideally in a distribution box (not in pati‐<br />
ents'/residents' rooms).<br />
- Easily accessible at all times (access space min. 60 cm width).<br />
- Heat dissipation must not be obstructed.<br />
- In the case of installation in switch cabinets etc., the heat loss<br />
must be dissipated by forced ventilation if necessary.<br />
- Due to the voltage drop, the power supply unit should, if possi‐<br />
ble, be housed close to the largest consumers.<br />
- Fire hazard! Heat is produced in short-circuit operation of<br />
power supply units. Make sure thatt here is sufficient ventilation<br />
in the distribution box.<br />
- After the outer cover is removed, the power section must re‐<br />
main covered.<br />
- The terminals for the nurse call system and the power system<br />
must differ from each other clearly, e.g. in shape and/or colour.<br />
Labelling alone is not a sufficient distinguishing feature.<br />
- Spatially separate arrangement.<br />
