CP electronics ELT10 Emergency Lighting Test Switch

PRODUCT INFORMATION

The ELT10 Emergency Lighting Test Switch is a device designed to test the function of emergency luminaires by interrupting the permanent live mains supply for pre-programmed time periods. It ensures a well-managed battery discharge, reducing the risk of depleting the battery life and performance. The device has three pre-programmed test intervals: 10 minutes, 1 hour (60 minutes), and 3 hours (180 minutes).

Wiring

When wiring the ELT10, follow the instructions below:

1. Isolate the mains supply to the circuit at the main distribution board.
2. Wire the ELT10 according to the provided diagram.
3. Connect to the Emergency lighting test switch via the terminal block:
   • Live (Permanent Live) supply to the L terminal
   • Neutral supply to the N terminal
   • For standard operation, connect the emergency lighting load to the NC terminal and loop the incoming permanent live to the COM terminal.
   • When using the ELT-REL relay unit, connect the relay to the NO terminal and loop the incoming permanent live to the COM terminal.
4. This device has a voltage-free changeover contact output.
5. Screw the unit to the wall.
6. Switch on the mains supply to the circuit at the main distribution board.

Operations

To test the emergency luminaires using the ELT10, follow these steps:

1. The unit will power up with the SUPPLY ON lamp illuminated,
   connecting the supply to the NC output and energizing the connected
   emergency luminaire loads.

2. To select a test time, turn and release the key switch:

   • Turn and release once to select the 10 minutes test interval.
   • Turn and release again to select the next test interval.

3. The supply will be disconnected from the NC output and connected to the emergency luminaire loads for the duration of the test.

4. During the test, the LED light adjacent to the selected test interval will indicate the time left. The SUPPLY ON LED will light up once the test is complete.

5. To cancel a test, turn and release the key switch until the SUPPLY ON LED illuminates.
   Warning: This device works at mains potential. Be sure to take care when working with electricity.

Overview

Product Dimensions

Wiring

The ELT10 Emergency Lighting Test Switch, is designed to test the function of emergency luminaires by interrupting the permanent live mains supply by pre- programmed time peri-ods. For security of operation a key switch is used. At the end of the selected time period the permanent live supply to the emergency luminaires is automatically re-instated. This results in a well-managed battery discharge, reducing the risk of depleting the battery life and performance.
Three pre-programmed test intervals are available:

• 10 minutes
• 1 hour (60 minutes)
• 3 hours (180 minutes)

2.  Wire the ELT10 as in the diagram above.
3.  Connect to the Emergency lighting test switch via the terminal block.
   • Live (Permanent Live) supply to the L terminal
   • Neutral supply to the N terminal
   • For standard operation connect the emergency lighting Load the NC terminal and Loop the incoming permanent live to the COM terminal
   • When using the ELT-REL relay unit, connect the relay to the NO terminal and Loop the incoming permanent live to the COM terminal
4. This device has a voltage free changeover contact output.
5. Screw unit to the wall.
6. Switch on the mains supply to the circuit at the main distribution board.
7. The SUPPLY ON lamp will light up (see the adjacent image).

Operations

Testing

1. The unit will power up with the SUPPLY ON lamp illuminated — NOTE the supply will be connected to the NC output energising the connected emergency luminaire loads.
2. To select a test time turn and release the key switch to select the 10 minutes test interval. Turn and release again to select the next test inter-val – the supply will be disconnected from the NC output and connected emergency luminaire loads for the duration of the test.
3. 10 minute test – The LED light adjacent to the 10 minutes will keep blinking during the test time. Once the test is complete the SUPPLY ON LED will light up.
4. 1 Hour test – The LED light adjacent to the 10 minutes will light up, and the 1 hour LED will keep blinking during the test time. On 10 minutes left to test the 10 minutes LED will start blinking. Once the test is complete the SUPPLY ON LED will light up.
5. 3 Hour test – The LED light adjacent to the 10 minutes and the 1 hour LED will light up and the 3 Hour LED will keep blinking during the test time. On 1 hour left to test the 1 hour LED will start blinking, on 10 minutes left to test the 10 minutes LED will start blinking. Once the test is complete the SUPPLY ON LED will light up.
6. The blinking of the LED denotes the test time left.
7. To cancel a test, turn and release the key switch until the SUPPLY ON LED illuminates.
