In addition, remote initiation can take place by means of a manually operated initiation device. e) A pneumatic non fail safe NSHEV, which does not open automatically on loss of power, shall have at least a thermal device and one power source in accordance with EN 12101-10, which is mounted directly in the NSHEV, unless the required control panel monitors the lines to the NSHEV and indicates a failure. In some specific design cases where it is suitable to initiate the NSHEV manually only, the NSHEV may be installed without an automatic initiation device. SIST EN 12101-2:2017
The specimen shall be installed in a heat tunnel in its most unfavourable position. The release behaviour for each test shall conform to (v + 3T) / 0,35 ≥ u where v is the nominal operating temperature of the thermal element and u is the release time (s). The static response behaviour of the thermal device shall be measured three times in accordance with the requirements of EN 54-5:2017, 5.3. The nominal release temperature for each test shall not vary by more than –3K to +8K. Smoke detectors shall comply with the requirements of EN 54-7 and heat detectors with EN 54-5. 4.1.2 Opening mechanism 4.1.2.1 General The NSHEV shall be provided with an opening mechanism with energy within the NSHEV, (e.g. gas containers, spring systems, electrical power supply) and/or with an external energy source. For the external links the manufacturer of the NSHEV shall specify the operating requirements for the initiation device and the opening mechanism, e.g. voltage, energy. 4.1.2.2 Integral gas containers Any gas container forming an integral part of the NSHEV shall be equipped with a pressure release device to prevent an explosion if the container overheats. The energy supply shall comply with EN 12101-10. 4.1.3 Inputs and outputs If the NSHEV is intended to operate with an external energy source it shall be equipped with inputs and/or outputs to allow connection of the NSHEV to the control panel and power supplies in accordance with EN 12101-10. 4.2 Response delay (response time) 4.2.1 Reliability The NSHEV shall when tested in accordance with Annex C open, i.e. reach its fire open position, within 60 s after actuation. 4.2.2 Opening under (snow/wind) load Roof mounted NSHEV shall open, reach its fire open position not more than 60 s after actuation and remain in position without an external energy supply (until reset), when tested under the snow load appropriate to its classification and under the specified side wind in accordance with Annex D.
