• Emergency lighting units must be operated on a non-switched phase with the voltage stated on them. Power must not be interrupted except for maintenance and testing purposes. Continuously turning off and on the line which the device is connected wears the fluorescent lamps and battery.

• Emergency lighting units must not be operated in environments where the temperature is not within the operating environment temperature threshold stated on the unit for long periods. If they are, this may cause damage in the device and the battery.

• Emergency lighting units must be operated in environments that comply with the IP Protection Class conditions that are stated on the units. Operating the device in environments other than those stated may cause damage in the device and the battery.

• The initial charging time of the battery is 48 hours for 1-hour capacity products and 96 hours for 3-hour capacity products. For the next charges, 24 hours for 1-hour capacity products and 48 hours for 3-hour capacity products are enough for the battery to be fully charged.

• When installing emergency lighting units, the battery must be connected to the emergency unit circuit when the luminaire is to be used. In cases where it takes time for the luminaire to be operative after the installation, the battery must be removed from its socket after the necessary controls.

• The emergency lighting units and emergency exit luminaires should not be stored inactive for too long since their batteries are already mounted. Batteries that remain inactive in the socket for long periods before the actual energy supply may irreversibly be damaged.

• A previously charged battery loses 15% of its capacity per month when it is not used. Thus, previously charged batteries must not remain inactive for more than 3 months. Uncharged batteries can remain inactive for 6 months in favorable storage conditions. It is not suggested to store the batteries under temperatures higher than 40°C.

• Batteries that remained inactive for a long time may require around two to ten charging cycles to reach full capacity.

• In emergency lighting unit installations, the unswitched line must be disconnected once in every six months and the battery capacities must be tested. Before this test is conducted, it must be checked that there were no interruptions in the line for 24 hours for 1-hour capacity products and 48 hours for 3-hour capacity products and that the battery is sufficiently
charged. Once this is checked, the power to the device must be cut and the “Emergency Lighting Duration” of the lamps must be controlled. It must be confirmed by the operator conducting the test that the lamps provide light for duration time that declerated by producer. The operator must inform the authorities that the batteries of the luminaires that cannot deliver the required performance have completed their life cycles.

• When the battery is to be changed, first the power to the device must be cut and then the old battery must be replaced with an equivalent battery. When replacing the battery, the use of lower than required capacity batteries may cause the device not to operate whereas the use of higher than required capacity batteries may cause the device to break down.

• Out of use batteries must not be thrown away with regular waste. They must be sent to waste collection centers or to the
manufacturer in order to be sent to these centers.
