The detector LEDs will blink green every 6 seconds under normal conditions. When in fault, an intelligent
addressable device will blink its address id to simplify locating the faulty device.
Blink pattern examples for faulty devices are given below.

The control panel automatically performs a detector initialisation routine when a detector is added or changed.
The detector initialisation routine takes approximately 2.5 minutes. During this time, the detector being initialised
does not perform fire protection functions. The LEDs of detectors polled in FlashScan mode will latch a steady
green while initialising, and return to blinking green when initialisation is over.
While initialising a detector, follow these guidelines:
• Make sure the detector is free of residual smoke during detector initialisation.
• Do not test a detector during detector initialisation.
NOTE: The control panel only performs detector initialisation if it senses that a detector was removed for
at least 15 seconds.
WARNING!!
If any detector is replaced with a different type of detector (for example, a laser detector is replaced with a
photoelectric detector), the control panel must be programmed immediately with the new detector Type Code.
Failure to do so can cause incorrect control panel operation, including false alarms.

You can set each detector, except FST-851/751 (Heat), for Self-Optimizing Pre-Alarm (PA=1). In this Self-
optimizing mode, the software measures the normal peak Analog readings and sets the Pre-Alarm level just
above these normal peaks. This allows extremely sensitive Pre-Alarm capability with reasonable protection
against non-fire signals. The figure below shows a graphical representation of the Self-Optimizing Pre-Alarm level:
