Self Testing Emergency Lighting
The self testing facility is a key advance in emergency lighting technology. Self test units automatically carry out their own weekly, quarterly and annual operation checks and display a warning light to alert the user if a fault is found within the unit. The electronics within each light automatically schedule and run the tests from the moment they are first powered up, requiring no user intervention.

Advantages
· Ensures all emergency light fittings are reguarly and properly tested.
· Saves the time and cost of manual maintenance.
· Clear red and green LED indications of the status of each unit.
· Button for manual testing if required.
· Promotes optimum battery performance.
· Various indicator states clearly show faults and the status of the battery.
· Self testing procedure is automatic requiring no programming or user intervention.

Why use this facility?
Emergency lighting systems are rarely properly tested and maintained even though consistent and correct testing is essential to ensure a fault free system. Because of the time involved, the user is often inclined to miss or cut short weekly tests. Functional checks are reduced to short durations that never fully test to see if the batteries inside can sustain the lights for the required duration. As batteries age their capacity dwindles, so eventually they reach a point where they cannot provide any decent light for any decent length of time. The fact that modern emergency lights are required to run for at least three hours further adds to the problem - such full duration tests are very time consuming. Self testing emergency lights take this tedious and time consuming manual task out of the hands of the user, ensuring sufficient testing is performed reliably and automatically for peace of mind and safety for the building`s occupants.

How does it work?
When the battery is first connected to the control board, the testing procedure commences. Exactly one week later, the light initiates its first weekly assessment - a short two minute burn of the lamp, which it does every following week. In the thirteenth week a complete duration test of three hours is implemented. Three hours is the required illumination period as specified by British Standard 5266. If the lamp fails to light or the batteries fail to last the duration, a fault indication is signalled by a red LED. A push-button next to the indicators can be used for manual testing if required.

Commissioning
Exactly twenty-four hours after the initiation of the timer, the first duration test will take place. This minimises the commissioning procedures necessary since this test will show any newly fitted units that fail to operate correctly. If necessary the battery will be fast charged. A completely discharged battery will be fully re-charged within twenty hours.

Mains Interruption or Test Button Push
If a mains supply interruption occurs during the twenty-four hours before a test is due, the test is automatically delayed in order that the batteries can be fully re-charged first. This delay does not affect future timings. Following a mains interruption, the lamp will remain lit (or running from batteries in the case of maintained units) for two minutes after the supply has been restored. Similarly the lamp will light and remain lit for two minutues following a push of the test button.

Indicator LED Status
Each unit has two indicator LEDs which light and/or blink in various combinations to indicate the current status of the unit. The following table gives details of these conditions. This information is also supplied with each light and a copy should be kept on site to aid day to day checks and future troubleshooting.

Green LED	Red LED	What does it mean?
On	Off	Stand-by, trickle charging - Normal state
Blinking	Off	Stand-by, fast charging
On	On	Stand-by, trickle charging, test delayed
Blinking	On	Stand-by, fast charging, test delayed
On	Blinking	Stand-by, trickle charging, lamp failed
Blinking	Blinking	Stand-by, fast charging, lamp failed
Off	Blinking	Emergency duration not sufficient, or charging current not correct

· Fault conditions always and only shown by a blinking red light.
· If the emergency duration is not sufficient please replace the battery. This also resets the timer (see above).
