Maintenance and testing
Maintenance
The unit should be maintained and tested according to local or
national requirements and any other applicable regulations. Do
not modify internal wiring or circuitry.
Testing
To activate an alarm, push the resettable element or turn the
key clockwise (one click). To reset the device, turn the key
anticlockwise (one click). Reset the control panel after testing.
Replacing the resettable element
Replace the resettable element (or add the breakable element)
as follows:
1. Unlock and remove the front cover as described in
“Installation” on page 2.
2. Push the element up, and then pull it out (see Figure 5).
3. Replace the resettable element (or add the breakable
element, if required).
4. Replace the front cover.
