– for the safety of persons,
– for avoiding damage to the environment or other material
NOTE Examples of safety services include
− emergency (escape) lighting,
− fire pumps,
− fire brigade lifts,
− alarm systems, such as fire alarms, smoke alarms, CO alarms and intruder alarms,
− evacuation systems,
− smoke extraction systems,
− essential medical equipment.

Replace clauses 556 to 556.8.1 by the following:
556 Safety services
556.1 General requirements
556.1.1 Safety services required to operate in fire conditions shall meet the following
requirements:
– a safety source shall maintain an electrical supply of adequate duration;
– equipment shall have a fire resistance of adequate duration either by suitable selection or
erection.
NOTE 1 Safety services may also be required to comply with additional national or local regulations.
NOTE 2 Two types of electrical supply source may exist: the safety source and the normal source.
NOTE 3 The normal source is, for example, the public supply network
556.1.2 For protection against indirect contact, protective measures without automatic
disconnection at the first fault are preferred.

---------------------- Page: 5 ----------------------

60364-5-55 Amend. 1 © IEC:2001 – 9 –
In IT systems continuous insulation monitoring devices shall be provided to give an audible
and visible indication of a first fault to earth.
556.2 Supplies to current-using equipment
Where electrical equipment is supplied by two different sources, a failure occurring in the
circuit from one source shall not impair the protection against electric shock or the correct
operation of the other source. Where such equipment requires a protective conductor, it shall
be connected to the protective conductors of both circuits.
556.3 Special requirements
556.3.1 Protection against short-circuit and against electric shock, under normal conditions
and in case of a fault, shall be ensured under any configuration of the normal and safety
sources of supply.
556.3.2 Protection against overload may be omitted where the loss of supply may cause a
greater hazard. Where protection against overload is omitted, the occurrence of an overload
shall be monitored.
556.3.3 Depending on whether the safety source is to operate in parallel with or
independently of the normal supply, the appropriate subclauses of clause 551 shall be taken
into account.
556.4 Switchgear and controlgear
556.4.1 Switchgear and controlgear shall be provided, either by construction, location or
erection, with protection ensuring fire resistance of adequate duration.
556.4.2 Controlgear shal
