How To SpecifyML2000ML20900 ECL SeriesSuggested SpecificationECOFLEX ELECTRIFIEDMORTISE LOCKSA. CORBIN RUSSWIN ML20900Electrified Mortise Locks1. General: BHMA certified extraheavy duty, lever type mortise lockconforming to ANSI 156.13 Series1000, Grade 1 requirements andANSI A117.1 accessibility guidelines.All functions manufactured in asingle sized case formed from aminimum 12 gauge steel. Lockset isfield-adjustable for handing withoutopening the lock body with abeveled armored front that is 0.125”minimum thickness and utilizes a onepiece3/4" anti-friction stainless steellatchbolt. To insure proper alignment,all trim, shall be thru-bolted and fullyinterchangeable between rose andescutcheon designs. Lock is UL listedand labeled for use on up to 3 hourfire rated openings.a. Backsets: 2-3/4”.b. Deadbolt: Optional 1" throw madeof stainless steel and 2 hardenedsteel roller inserts.c. Strikes: Provide wrought boxesand strikes with proper lip lengthto protect trim but not to projectmore than 1/8” beyond trim, frameor inactive leaf. Where required,provide open back strike andprotected to allow practical andsecure operation.2. Provide access control mortise lockseries, type and functions wherespecified in hardware groups, withprovisions below:a. Emergency override accesscapability with key cylinderretraction of lock latch bolt withoutnecessary electronic activation.b. Inside lever retracts latch anddeadbolt simultaneously for freeegress.c. Refer to "KEYING" specificationsection for keying systemrequirements.d. Lever and finish to matchcorresponding mechanical lockinghardware.3. Locking and unlocking of the leverhandle by electronic operationcontained completely within the bodyof the mortise lock.a. Field configurable Fail Safe /FailSecure by means of an external DIPswitch setting.b. Operationally voltage-insensitive 12to 24 VDC.c. Energy Performance: Maximumstandby current required forfunctional operation not to exceed50 mA at 24 VDC limiting potentialinductive kickback or the need forexternal diodes.d. Functional locking operation notaffected by cable runs greaterthan 500 feet using a minimum 22AWG wire.4. Monitoring: Optional real timemonitoring of latchbolt, deadbolt, dooropen/closed status and valid egresswhere specified. Valid egress signaledby activation of the Request-to-Exit (RX)micro switch integral to the inside leverof the lockset on the unsecure side ofthe door capable of shunting externalalarms. Door open/closed statusprovided by monitoring the deadlatchand latchbolt in series with optionalintegrated magnetic door positionswitch.5.
