Model ‘F’ lock series 4KL function - Internal Handle, External Key Acces and Self Latching
A solution to perimeter fire door security
The Model F Four Point Self-Latching Lock (MFSL) has been designed specifically to suit fire doors fitted to the perimeter of buildings. Under Australian Standard AS 1905 Part 1 fire doors must be self-latching. Traditional fire door locksets use short tapered tongues, usually 12 mm long, to latch into the striker plate mounted on the door frame. This combined with the fact that egress fire doors open out means that they are susceptible to tampering and forced entry. The Rivers MFSL provides a solution to this security weakness.
Features
The Rivers MFSL Lock is a high security multiple point self-latching lock based on the heavily specified and commercially successful Rivers Model ‘D’ Lock series. The MFSL Lock utilises two 32 mm x 10 mm zinc plated steel locking bars that throw 45 mm to each locking point. This is substantial security improvement on traditional fire door locksets. Fire doors use door closers to return the door leaf to the closed position after being opened. The Rivers MFSL lock has a release latch that triggers the locking bars that engage into latch slots prepared in the door frame. The Rivers MFSL Lock thereby creates a substantial security barrier.
The Rivers MFSL Lock is adjustable to suit door widths from 760 mm up to 960 mm. For door widths from 961 to 1190mm our “long body” must be specified. Locks to suit door widths under 760 mm or over 1190mm can be made to order. All Rivers MFSL Locks are fitted with an internal lever handle that rotates downward through ninety degrees to disengage the locking bars. As a result the MFSL Lock complies with the Building Code of Australia for use in emergency egress applications. External access models are supplied with 201 cylinder and they can be master keyed by locksmiths.
Testing & approvals
Rivers two and four point lock configurations have been tested by the CSIRO in a Pilot Fire Test reference FSP 0415. CSIRO Assessment Number FCO-1240 confirms that Rivers two and four point locks will not prejudice the fire resistance of Trafalgar fire rated doorsets for Fire Resistant Levels (FRL) up to -/240/30.
BRANZ Assessment Report FAR 2684 and Fire Test Certificate No 426 confirm that the Rivers two and four point locks will not prejudice the fire resistance of Pyropanel FR, Pyrolit and Pandor fire doorsets for RFL’s up to -/240/30.
