1 Scope This European Standard specifies requirements, test methods and performance criteria against which the effectiveness and reliability of routing equipment capable of transmitting fire alarm and/or fault warning signals for use with fire detection and fire alarm systems installed in buildings can be assessed (see EN 54-1). The routing equipment is designed to allow the system to function in accordance with the requirements of this European Standard. It also provides for the evaluation of conformity of the equipment to the requirements of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

The version reference or references shall be in accordance with the documentation of 7.10.2.1. 7.10.5.3 For site specific data, the following requirements shall apply: a) the alteration of site specific data shall only be possible at access level 3 or 4; b) the alteration of site specific data shall not affect the structure of the program; c) if stored in volatile memory, the site-specific data shall be protected against power loss by a back-up energy source which can only be separated from the memory at access level 4, and which is capable of maintaining the memory contents for at least 2 weeks; d) if stored in read-write memory, there shall be a mechanism which prevents the memory being written to during normal operation at access level 1 or 2, such that its contents are protected during a failure in program execution;

15 °C – 35 °C, Relative humidity:
25 % – 75 %, Air pressure:
86 kPa –106 kPa. The temperature and humidity shall be substantially constant for each environmental test where the standard atmospheric conditions are applied.

(-5 ± 3) °C, Duration:
16 h. 10.4.2.5 Measurements during conditioning Monitor the specimen during the conditioning period to detect any change in status. During the last hour of the conditioning period, subject the specimen to the functional test. 10.4.2.6 Final measurements After the recovery period, subject the specimen to the functional test and inspect it visually for mechanical damage both externally and internally. 10.5
Damp heat, steady state (operational) 10.5.1 Object of the test The object of the test is to demonstrate the ability of the specimen to function correctly at high relative humidity (without condensation), which may occur for short periods in the service environment. 10.5.2 Test procedure 10.5.2.1 General Use the test procedure described in EN 60068-2-78. 10.5.2.2 Initial examination Before conditioning, subject the specimen to the functional test. 10.5.2.3 State of the specimen during conditioning Mount the specimen as specified in 10.1.3 and connect it to suitable power supply, monitoring and loading equipment (see 10.1.4). The specimen shall be in the quiescent condition. 10.5.2.4 Conditioning Apply the following severity of conditioning: Temperature:
(40 ± 2) °C, Relative humidity:
(93 23+−) %, Duration:
4 days. Pre-condition the specimen at the conditioning temperature (40 ± 2) °C until temperature stability has been reached, to prevent the formation of water droplets on the specimen.
