EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62642-4 testing. IEC EN 62642-4 contains requirements for burglar alarm and warning devices used for notification in burglar alarm systems installed in buildings. IEC EN 62642-1 describes the four warning device ratings corresponding to each of the four safety degrees given. Requirements are given for all four environmental classes covering indoor and outdoor applications as specified in IEC EN 62599-1.
This standard considers two different categories of warning devices: remote-powered and self-powered devices. Self-powered warning devices are classified as one of four types, depending on the charging characteristics of the storage device and the source of charging power.
Electrical connection means shall be suitable for the physical dimensions and current carrying capacities of the required conductors. The termination method must not damage the conductors. Terminals and other components used for connections must be identifiable by numbers or other markings specified in the documentation.
When the excitation device is subjected to a step between maximum and minimum in the input voltage or vice versa, there will be no change in the state of the exciter and no signal or message will be produced.
The standstill and peak current consumption of the warning device at each connection must not exceed those specified by the manufacturer at the rated supply voltage, with and without alarm audible.
The voltage of non-rechargeable storage devices will be constantly monitored. The voltage of rechargeable storage devices should only be monitored when the warning device is in standby.
A storage device undervoltage fault occurs when the voltage of the storage device drops below that specified by the warning device manufacturer. This voltage will be greater than the minimum voltage required to operate the warning device.
