ELTD1
Emergency Lighting Test Switch Electronic Thermostat
Overview
The ELTD1 emergency lighting test switch is designed to test the function
of emergency luminaires. A push button 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.
Four pre-programmed test intervals are available:
10 minutes
30 minutes
1 hour
3 hours
The unit will power up with the NORMAL lamp illuminated—the supply will
be connected to the output.
Push the test button to select the 10 minute test interval. Push 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, repeatedly press the button until the NORMAL lamp illuminates.
Installation
