Technical overview
The Gent ALD-302 is a ceiling-mounted anti-ligature base from the S4 Bases & Accessories range, designed for secure facilities. It features an anti-tamper lip to prevent contraband storage and incorporates a built-in magnetic switch that maintains loop continuity when multiple units are installed. Certified to a 6.4kg release load, it helps ensure occupant safety by detaching under excessive force while preventing ligature points.
Measuring 138 mm in diameter and 30 mm in height, the ALD-302 weighs 0.16kg and is covered by patent . It is approved for in-cell detection by the National Offender Management Services (NOMS) in England. To maintain loop integrity, resistance should be monitored during and after commissioning, as excessive quantities may compromise performance. The device is part of the S-Quad range and provides additional safety to occupants within secure facilities by minimising ligature risks and preventing unauthorised item concealment through its specialised design.
