TSS Fire Brigade FB1 and FB2 mortice deadlocks provide secure, reliable access control for communal areas such as dry risers, utility cupboards, car parks, and bin stores. Designed for emergency situations, these deadlocks allow authorised personnel and fire services to unlock the deadbolt from either side using a key, ensuring rapid entry without damage. Keys are sold separately, with specific codes for each lock model (FB1 uses TSSFB1K; FB2 uses TSSFB2K). Verify local fire brigade key requirements before ordering to ensure compatibility.
