EN 54-18 Fire Detection and Fire Alarm System - Test for Input and Output Devices

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 54-18 test. This standard specifies the requirements, test methods and performance criteria for input and output devices connected to the transmission path of a fire detection and fire alarm system used to receive or transmit electrical signals from or to the transmission path necessary for operation.

For input/output devices integrated into another device covered by this standard, environmental conditioning should be performed according to this standard with the addition of functional tests before, during and/or after conditioning.

In some detector standards, dry heat (operational) testing is done in special test equipment (eg in a heat tunnel for heat detectors). Necessary functional tests of the integrated input/output device before, during and after dry heat conditioning can be performed on this equipment, if possible without disturbing the detector measurements. Otherwise, a separate dry heat test will be performed with the same conditioning. The test temperature for heat detectors is the maximum application temperature.

If an I/O device is detachable (ie attached to a detachable mounting base), then a means must be provided for a remote monitoring system (eg control and indication equipment) to detect that the device has been removed from the base.

Each input/output device will be clearly marked with the following information:

• Number and date of the standard;
• The name or trademark of the manufacturer or supplier;
• Model designation (type or number);
• Wiring terminal definitions;
• Some mark(s) or code(s) that the manufacturer may identify

If any markings on the device use symbols or abbreviations that are not commonly used, these should be explained in the data supplied with the device. The mark will be visible during installation and accessible during maintenance. Marks should not be placed on screws or other easily removable parts.
