The SMART ES25 EMERGENCY PACK is a DALI compatible digitally addressable lighting interface emergency control unit. The ES DALI operates seamlessly like a TLX unit i.e. provides 100% light output for one hour with any 230Vac lamp. There are no functional differences from ordinary emergency lighting control units and so no special training is required for manufacturing and installation personnel. The unit complies with the Digitally Addressable Lighting Interface (DALI) Standard IEC 62386 and is therefore compatible with all international interfaces. Its bi-directional bus uses standard protocol and can therefore be addressed by all reputable bridges. The emergency function and system status can be addressed from a computer to perform tests to check system integrity. The SMART ES25 EMERGENCY PACK uses a standard 12V lead-acid battery and complies with SANS 1464-22 in terms of emergency performance, electrical safety and battery charging.

The SMART ES25 EMERGENCY PACK has 2 types of test modes:
> A short function test that checks the functionality of the unit and checks the lamp and battery, the test lasts for 1 minute and 50 seconds.
> A long duration test, which lasts for 40 minutes and will help remove battery memory. This test also checks the lamp and battery for faults.

When performing a test and a fault is detected, the unit will end the test and record the fault, it will only report the fault once it is queried with various commands.
