Appendix F: Detector Initialization
F.1 Overview
The control panel automatically performs a detector initialization routine when a detector is added
or changed.
The detector initialization routine takes approximately 2.5 minutes. During this time, the detector
being initialized does not perform fire protection functions. The LEDs of detectors polled in
FlashScan mode will latch a steady green while initializing, and return to blinking green when
initialization is over.
While initializing a detector, follow these guidelines:
• Make sure the detector is free of residual smoke during detector initialization.
• Do not test a detector during detector initialization.
F.2 To Replace a Detector with a Different Type of Detector
If one type of detector is replaced with a different type of detector, the control panel must
immediately be programmed for the new detector type. To replace a detector, follow these steps:
NOTE: The control panel only performs detector initialization 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.
Step Action
1 Delete the old detector point from FACP programming using the “Delete Point” screen on page
page 57.
2 Physically remove the old detector.
3 Enter point programming for this point and change the Type and FlashScan Code Label to the
values appropriate for the new detector. (Refer to Section 3.4.1, “Detector Point”, on page 40 for
programming instructions).
4 Physically install the new detector. Initialization will occur automatically
