A solution to perimeter fire door security
The Model D Self Latching Lock (MDSL) 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 MDSL provides a solution to this security weakness.
The Rivers MDSL Lock is a high security multiple point self-latching lock based on the heavily specified and commercially successful Rivers Model ‘D’ Lock series. The MDSL Lock utilises two 32 mm x 10 mm zinc plated steel locking bars that throw 45 mm to each locking point. This is a 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 MDSL lock has a release latch that triggers the locking bars that engage into latch slots prepared in the door frame. The Rivers MDSL Lock thereby creates a substantial security barrier. The Rivers MDSL Lock is adjustable to suit door widths from 760 mm up to 960 mm. For door widths under 760 mm or from 961 to 1190 mm our ‘long body’ must be specified. Other sizes can be made by special order.
All Rivers MDSL Locks are fitted with an internal lever handle that rotates downward through ninety degrees to disengage the locking bars. As a result the MDSL Lock complies with the Building Code of Australia for use in emergency egress applications. The locks are supplied with a 201 cylinder and they can be master keyed by locksmiths.
Rivers Model D Locks have been assessed to comply with Schools Facilities Standards – Section SS455 Door Hardware. Rivers Model D Locks achieved a Scale 7 rating under Australian Standard AS4145.2 testing.
