Alarm Lock P5849 US3 – Frequently Asked Questions

1) Will the Alarm Lock P5849 latch work with my DL2700 keypad lock?
The P5849 latch assembly is made for the Alarm Lock DL2700, DL2800 and DL3000 series cylindrical locks. It is the replacement latch for those bodies, so if the lock on the door is one of those three families, this is the part. For any other brand or series of lock, it is not a fit.
2) What backset does the Alarm Lock P5849 latch have, and will it drop into my existing door prep?
It is a 2-3/8 inch backset latch. That is the shorter of the two standard backsets on cylindrical door prep, the other being 2-3/4 inch. Measure from the door edge to the center of the bore: if that reads 2-3/4 inch, the P5849 will not line up with the existing hole and you need the 2-3/4 inch latch for the DL series instead.
3) Can I use the P5849 latch on a fire rated door without losing the rating?
Yes. The P5849 latch is UL listed and carries a 3 hour fire rating, so it can go into a fire rated opening served by a DL2700, DL2800 or DL3000 lock. Swapping in a non-rated latch is what breaks the assembly's rating, which is the usual reason a facilities crew ends up failing an inspection after a repair.
4) Is the P5849 a complete lock or just the latch?
Just the latch. The P5849 is the latch assembly only, the part that lives in the door edge and throws into the strike. It has no keypad, no cylinder, no lever and no strike, and it only serves as a replacement inside an existing DL2700, DL2800 or DL3000 lock. If the whole lock is failing rather than the latch, you are buying a lock body, not this.
5) Is the Alarm Lock P5849 latch assembly interchangeable with a Schlage PM010 mortise latch?
No. The P5849 is a replacement latch built for Alarm Lock DL2700, DL2800, and DL3000 cylindrical locks at a 2-3/8 inch backset, so it drops into those chassis and nothing else. The Schlage PM010 is a complete Grade 1 passage latch mortise lock in the PM Series, not a service part for a keypad cylindrical chassis. If a DL2700 latch has failed, order the P5849; if the door is getting a new mortise lock body, the PM010 is the product to look at.
6) The DL2700 on our stairwell door has a worn latch and the opening is fire rated - what else holds a 3 hour rating?
The P5849 latch is UL listed and maintains a 3 hour fire rating, which is why it is the right service part for a fire rated DL2700 opening. If the whole lock is being replaced rather than the latch, the Schlage Electronics LEMD-GRW carries a 3 hour fire rating as a Grade 1 ENGAGE Series wireless mortise lock, and the Schlage Electronics LEBMB-ADD carries a 3 hour fire rating as a Grade 2 LE Series mobile enabled mortise lock. Those two change the door prep from cylindrical to mortise, so confirm the existing prep before switching.
7) We are replacing the whole Alarm Lock DL2700 instead of just the latch - what keypad lock takes its place?
Once you go past the P5849 latch and replace the lock body, the pushbutton and keypad options are mortise rather than cylindrical. The BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock in the E-Plex 2000 Series, and the Dormakaba PowerPlex P2066 is a PowerPlex 2000 Series mortise lock. The Accentra NTM623-NR nexTouch Generation 3 uses a capacitive touchscreen keypad with cylinder override and no deadbolt. All four require a mortise pocket, so the door will need new prep coming off a cylindrical DL2700.
8) I need a full mortise lock, not a latch part. What should I be looking at instead?
The P5849 is a cylindrical latch component, so it will not serve a mortise pocket at all. For a mortise lock body, the Cal-Royal NM8050 covers Grade 1 entrance/office on a 1-3/4 inch door, the NM8080 is the Grade 1 storeroom version with an interchangeable core option, and the Corbin Russwin ML2003 is the Grade 1 classroom function in the ML2000 Series. Those are complete locksets, not replacement latches.
9) Can I use a Codelocks CL2255 electronic tubular mortise latch in place of the Alarm Lock P5849?
The names read alike but the parts are not equivalent. The P5849 is a mechanical replacement latch for the Alarm Lock DL2700, DL2800, and DL3000 chassis with a 2-3/8 inch backset. The Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 Series with a brushed steel finish - it is its own coded latch, not a service component for an Alarm Lock keypad chassis. Keeping an existing DL series lock in service means the P5849.
10) Our opening needs a keyed storeroom function rather than an entry latch - what should we specify?
The P5849 latch supports an entry function on the DL series chassis it services. For a storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option, and the Command Access ML190 is a heavy-duty storeroom motorized mortise lock with field selectable EL/EU operation on 24VDC. The Command Access unit is the one to pick if the storeroom door also needs to be released from an access control system.
11) What is the difference between ordering the Alarm Lock P5849 latch and a Sargent 4874 mortise deadbolt?
They do different jobs on the door. The P5849 is a latch assembly at a 2-3/8 inch backset that handles the latching action of a DL2700, DL2800, or DL3000 lock. The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset - a separate bolt requiring key operation from both sides, commonly added above a lock rather than replacing its latch. Note the backsets differ, so the 4874 does not go into a 2-3/8 inch prep.
12) The door only needs to latch, with no locking at all - is the P5849 the right part?
The P5849 is a latch for an entry function DL series lock, so it belongs on an opening that locks. For a hall, closet, or corridor door that only needs to latch, the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock in the MA Series with field reversible operation and a fire rating, the Hager 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, and the Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors. The PC10 keeps a cylindrical prep; the other two are mortise.
13) Our apartment entry doors are 1-3/4 inch and thicker - what mortise lock bodies suit that opening?
The P5849 latch serves entry function DL series locks at a 2-3/8 inch backset. For apartment entry doors, the Baldwin 6301 is an entrance/apartment mortise lock body, knob by knob, with a 2-1/2 inch backset for doors 1-3/4 inch and over, and the Baldwin 6301LS is the same function in a lever by lever configuration. If the opening is entrance/storeroom instead, the Baldwin 6310 covers doors 1-3/8 inch and over at the same 2-1/2 inch backset. Check the door prep, since the 2-1/2 inch backset differs from the P5849 dimension.
14) Does the P5849 latch handle, or is it reversible?
Entry function is what this latch serves, and it is sold as a single part rather than a left and right version. Order by backset and finish. If you are specifying a lock body where handing does come up, that is a question for the chassis, not the latch.
15) What finishes does the Alarm Lock P5849 latch come in, and do peer mortise locks match?
The P5849 latch assembly is offered in oil rubbed bronze, satin chrome, and bright brass. Among comparable locks, the Marks USA 5PDN hospital passage push/pull paddleset is a Grade 1 195 Series device in satin stainless steel, and the TownSteel MRX-A-01 passage mortise lockset is a Grade 1 heavy duty satin stainless steel arch trim device - both a different family of finish from the bronze and brass tones. Matching the latch faceplate to existing trim is usually the deciding factor on a repair.
16) Will a Schlage L0170 half dummy trim work where the Alarm Lock P5849 latch is used?
No, and the distinction matters on the order. The P5849 is a working latch assembly - it engages the strike and secures an entry function opening. The Schlage L0170 is a Grade 1 half dummy trim in the L Series for 1-3/4 inch doors, a non-keyed dummy with no latching mechanism at all, used on inactive leaves and pull-only doors. A dummy device cannot replace a failed latch.
