Guardian 600SL: identify the legacy manual and beep signals
Guardian's current support FAQ explicitly includes 600SL; its older manual also carries installer branding.

Identifier: 600SL. Keep every letter and suffix on your product label when checking applicability.
The 6-13 owner reference identifies Guardian 600SL. Its GDS installer branding is historical document context and does not establish an Anderson affiliation.
Guardian associates 20 closing beeps with a photo-eye obstruction signal. Check for visible obstructions; repeated faults need service rather than a safety-system bypass.
Twelve beeps indicate abnormal motion or missing motion information and can have several causes. The beep count alone does not identify a failed replacement part.
