Product Guide
Emergency Lighting Test Switch
The ELT10 emergency lighting test switch is designed to test the function
of emergency luminaires. A key switch is used to interrupt the supply to
the luminaires for a pre-programmed period of time. At the end of the
time period the supply to the luminaires is automatically re-instated. The
result is that there is no risk of depleting the batteries in the emergency
fitting.
Three pre-programmed test intervals are available:
10 minutes
1 hour
3 hours
The unit will power up with the SUPPLY ON lamp illuminated—the supply
will be connected to the output.
Turn and release the key switch to select the 10 minute test interval. Turn
and release again to select the next test interval—the supply will be disconnected from the output for the duration of the test.
To cancel a test, turn and release the keyswitch until the SUPPLY ON
lamp illuminates.
Overview

1. Make sure the load is connected and in working order.
2. Isolate the mains supply to the circuit at the main distribution board.
3. Wire the ELT10 as in the diagram above.
4. Connect the controller via the terminal block. Live supply to the L terminal, Neutral supply to the N terminal.
This device has a voltage free changeover contact output.
For standard operation connect the load to the NC terminal and loop the live to the COM terminal.
When using the ELT-REL relay unit, connect to the NO terminal and loop the live to the COM terminal.
