Self powered warning devices are classified into one of four types, dependent upon the recharge characteristics of the storage device and the source of recharge power. These four types are defined in Table 8. 5 Requirements 5.1 Functional 5.1.1 Response Depending upon the grade, warning devices shall have the functionality as defined in Table 1. Where a function is provided, the warning device shall operate in accordance with the requirements of Table 2.

For grade 3 and grade 4 warning devices, if the loss of remote power source can be shown to be caused by a fault then a fault signal shall be generated, otherwise a tamper signal shall be generated. c At least one of these actions shall occur at the warning device. For grade 3 and grade 4 warning devices, if the loss of trigger command integrity can be shown to be caused by a fault then a fault signal shall be generated, otherwise a tamper signal shall be generated. d The response to a remote test pass shall be different from the response to a remote test fail.
5.1.2 Acoustic A warning device shall produce a varying sound output, which is distinctive and likely to attract attention, with a mean acoustic output of no less than that defined in Table 3 at 1 m from the mounting surface of the warning device throughout the manufacturers specified operating voltage range. Peak acoustic output levels, taken at 30° intervals in the horizontal plane, shall not be below the minimum individual level defined in Table 3 at 1 m from the mounting surface. The mean acoustic output shall be calculated by the arithmetic sum of these values divided by the number of measurements. For surface mounted devices (e.g. wall mounted devices) this is required at angles between 15° and 165° to the surface, and for pole mounted devices it is for the full 360°.

Internal warning device External warning device Minimum mean acoustic output level 80 dB(A) 100 dB(A) Minimum individual acoustic output level 75 dB(A) 95 dB(A)
NOTE 1 It is considered restrictive to define exact waveforms of acceptable alarm tones, therefore the only tests that can be applied are on the acoustic output level and that the tone is varying. NOTE 2 Voice alarms are deemed to meet the requirements of a varying sound output. NOTE 3 A warning device may also provide audible alert indications providing such indications are easily distinguishable from an alarm. NOTE 4 The acoustic output (sound level and/or frequency) of a warning device may be subject to variation depending on local or national requirements. 5.1.3 Timing
A trigger command exceeding 400 ms shall be processed by the warning device. A warning device shall commence its audible alarm within 1 s of receiving a valid trigger command to do so. It shall cease its audible alarm within 1 s of receiving a valid cancellation of the trigger command. The warning device shall sound between these signals. The maximum time for which an audible warning device shall sound continuously is 15 min. NOTE 1 Where applicable this requirement may be achieved by the CIE. NOTE 2 The duration of the operational period of a warning device may be subject to variation depending on local or national requirements A tamper signal or message shall be generated within 1 s of a tamper condition occurring. There shall be a response to loss of remote power source or loss of trigger command interconnection integrity according to Tables 1 and 2, within 10 s of the fault occurring. A response to local test fail according to Tables 1 and 2 shall occur within 10 s of detection of the fault. 5.2 Tamper 5.2.1 Protection All component parts shall be housed in an enclosure meeting the impact requirements of the appropriate grade given in Table 4. Provision shall be made to allow adequate fixing of the enclosure to the mounting surface. SIST EN 50131-4:2009

The cover of the enclosure shall be opened only with the use of one or more keys or suitable tools. It shall not be possible, without causing visible damage, to gain access to any electrical connections, or elements providing adjustment, without first generating a tamper signal or message. When the unit is mounted normally it shall not be possible, without causing visible damage, to introduce a tool, as defined in Table 5, such that the operation of the warning device could be adversely affected.

Opening the warning device enclosure by normal means shall generate a tamper signal or message. The enclosure shall not permit the introduction of a tool of dimension as specified in Table 5 and type as specified in EN 60529, to defeat the tamper detection. Attempts to remove the warning device from its mounting surface for a distance defined in Table 7 in a perpendicular direction shall generate a tamper signal or message according to Table 6.
It shall not be possible to defeat the removal from mounting detection by sliding a 25 mm x 1 mm x 300 mm blade, or by use of pliers (of thickness 5 mm and reach 150 mm), between the mounting surface and the warning device.
The warning device shall include means to detect penetration of the enclosure, which could cause mis-operation of the warning device, as specified in Table 6, when a hole of 4 mm is made in the enclosure. SIST EN 50131-4:2009

5.3 Environmental The environmental classification shall be as described in EN 50131-1. All the relevant environmental tests shall be carried out at the appropriate level for all security grades, as given in EN 50130-5. The warning device shall meet the requirements of the relevant environmental class as specified by the manufacturer. For operational tests, the warning device shall not generate unintentional activations, tamper, fault or other signals or messages, when subjected to the specified range of environmental conditions. For endurance tests, the warning device shall continue to meet the requirements of this European Standard after being subjected to the specified range of environmental conditions. See 6.9 for the relevant tests and severity. 5.4 EMC For all grades of WD the WD shall not generate or be affected by the EMC conditions and severity levels defined in EN 50130-4 and EN 61000-6-3. 5.5 Safety The warning device shall provide protection against electrical shock and consequential hazards by compliance with the requirements of EN 60950-1 or EN 60065.

This storage device has no means of recharge, and will need replacing before it is completely exhausted. NOTE 2 A type X warning device could, for example, be remotely powered from the I&HAS and with a dry cell as its storage device. This storage device has no means of recharge, and will need replacing before it is completely exhausted. NOTE 3 A type Y warning device could, for example, recharge its storage device by means of a solar cell, or connection to an external power source (e.g. mains supply). NOTE 4 A type Z warning device could, for example, be normally powered from the I&HAS, and this power source is also used to recharge its storage device.
At the end of the standby period, the storage device shall meet the operating time requirements of 5.6.3.1. For types X and Z, where loss of remote power supply causes the warning device to activate (see Table 2) then the requirements of Table 8 do not apply, and the storage device shall only meet the operating time requirements of 5.6.3.1. 5.6.3.3 Recharge rate Type Y and Z warning devices shall be capable of supplying current at the appropriate voltage to recharge the storage device equivalent to 80 % of that supplied by the storage device in meeting the requirements of 5.6.3.1 and 5.6.3.2 within the periods as specified in Table 9.
