The facility of displaying and adjusting detector data— especially regarding
addressable & analogue detectors — is of great importance for adapting your
fire alarm system to the site environment.
The following detector data may be accessed:
• Current analogue values, limits and maximum & minimum values.

Addressable & analogue detectors sense the conditions in the area being
protected, producing an analogue signal which changes with smoke density and
temperature.
This detector converts the signal from analogue to digital data and transmits it
to the control panel.
The following standard set-up of threshold alarm levels is recommended for
monitors installed in a normal clean atmosphere:
