The LKM7004 Exit Device by Lockmasters
Q: What is the fire rating of the LKM7000 product line?
A: The current fire rating of the LKM7000 product is 90 minutes when installed with the stainless steel strikes that are now standard and a Kaba Mas X-10 lock or mechanical combination lock. The locks when installed with a Sargent & Greenleaf 2740 lock are not fire rated.
Q: What voltage or amperage is required for locks to use access control?
A: The locks work on 12- or 24-volt DC power and require only a .5 amp.
Q: Can these locks be used with an electric strike?
A: No, these locks cannot be used with an electric strike. All doors should be prepped for a raceway. The locks will require an electric hinge or an electric power transfer (EPT) to power the access control solenoid. For doors that are being retrofitted without a raceway an armored door loop or an external wire conduit of various types may be used. To just activate the solenoid and not use monitoring a two-wire device is needed but if all switches are being used then an 8-wire EPT or electric hinge is needed.
Q: What key cylinder is provided with the LKM7003 and LKM7006 locks?
A: No key cylinder or cores are provided with the key override LKM7000 locks. Please see "Companion Items" above for all cylinder options.
Q: What is the security role of the FF-L-2740 lock (i.e., X-10) or combination lock installed inside the LKM7000 product on the door? Can it be overridden by the key in the override?
A: The combination lock cannot be overridden by the key override. The combination lock must be in the open position for the key override or the access control device to work for access. The device is King of the door and is an independent lock within the lock. The warranty of the combinatino lock is a separate one from the LKM7000 product. The manufacturer warranty of the combination lock covers any failure of that device. You can use any standard combination lock. The X-10 is the most popular with the door hardware that must meet FF-L-2740A and FF-L-2890.
Q: What are the switches in the lock used for?
A: You can monitor whether the X-10 is open or closed. You can use the bolt switch for a request to exit and relay alarms, sirens, magnetic locks, and door assist devices off of that switch. Both switches are status switches and simply open or close. How your alarm or monitoring system interprets the change in movement is up to the setting of your equipment.
Q: How do I prep the door for LKM7000 product?
A: It is preferable that the lock is field-prepped by an installer with the LKM7000IFAC installation fixture. These locks are positioned on the door off the strike. The recommended placement of the lock is 43 inches AFF. However, placement between 41-44 inches AFF on the door will not affect the function of the lock and will keep all parts of the lock within the range of ADA. On hollow metal doors and wood veneer doors we recommend standoff kits LKM7000SOK1 for 1-3/4" doors or LKM7000SOK for 2-inch doors. There is also a 700013S01EXT, which allows the LKM7000, LKM7003, LKM7004 and LKM7006 to be used on doors with a thickness greater than 2-3/4".
Q: How can this lock be used on double door applications?
A: The inactive leaf must be fixed in place and locked securely before the lock is latched when a mullion is used. The active door must not slam against the inactive leaf strike or the lock's encapsulated strike will break.
Q: How can you convert an LKM7002 exit only lock to one of the other versions?
A: You cannot convert the LKM7002. You must replace it with one of the other locks.
Q: How can you convert the LKM7000 to an LKM70003 or an LKM7004 to an LKM7006?
A: If you add the key override module LKM7001 to a LKM7000/LKM7004 you can cover the lock to an LKM7003/LKM7006. The internal solenoid in the LKM7000/LKM7004 needs to be removed since the LKM7001 has a solenoid in it. The LKM7004 and LKM7006 have a removable metal cover that can be removed if an X-10 lock or other combination lock needs to be added to the door to make an LKM7000 or LKM7003 lock.
Q: What version of the X-10 lock should be used with the LKM7000 Product Line?
A: The LKM7000 Product Line uses the safe lock version of the X-10. Please do not specify a CDX-10 with any LKM7000 product. If a CDX-10 is currently being used on the door you can purchase an LKM7000CK10 kit to convert the lock to a regular X-10 so it can be reused inside of the LKM7000.
Q: What is the Key Override Module?
A: Standard on the LKM7003 and LKM7006 Lock, this module "overrides" the access control device with the turn of a key, but not the combination lock. This feature is particularly important during the event of a power outage, failure or malfunction of an access control device, or an emergency that requires expedited entry.
Q: What is the Lock Down Feature?
A: Ideal for controlling the flow of traffic through one door in areas with only one level of security and multiple entrances. Entrance is denied with a turn of a key without impending exit. The Lock Down Feature is comprised of a key cylinder installed into the Inside Base Plate. Standard on the LKM7004 & 7006, but available as a special order on other locks in the series.
