Key takeaways
- For swing gates, the chart's maximum weight and maximum length are separate figures: the CSW24UL product guide gives 1,600 lbs. at 8 ft. but 600 lbs. at 18 ft.
- For three models, LiftMaster's installation manuals list fewer usage classes than its product guides do; the usage class section names them.
- The chart lists battery backup from 20 to 500 cycles for ten models, no battery backup figure for the two AC-powered models, and solar power as standard for one linear actuator.
- The CSL24UL manual says: "A minimum of two independent monitored entrapment protection devices are required to be installed at each entrapment zone."
- The KPW250 wireless keypad holds up to 250 permanent four-digit PINs and the KPW5 up to 5. This page does not reproduce programming steps or codes.

Which LiftMaster gate operator do I have?
LiftMaster's feature chart lists seven swing operators, three of them linear actuators, and six slide operators. The table gives each one's chart description, maximum gate weight, maximum gate length and recommended cycles.
The chart's fourteenth model, described there as a specialty overhead operator, is not covered here. LiftMaster's gate operators category page also lists the MA, MAS, MAT, MAST and other models this page does not cover. For how readers, keypads and controllers fit together at a door or gate, see how commercial access control works.
For the 1 HP SL3000UL, the product page headline, the chart and the installation manual give 2,000 lbs., while a second tile on the same product page reads "1 HP Rated for gates up to 50 feet in length and 1,500 lbs."

Swing gates
Will it move my swing gate?
On a swing gate, the weight an operator can move falls as the gate gets longer. The chart gives each swing operator one maximum weight and one maximum length, and the CSW24UL product page words it as "Rated For gates up to 18ft. or 1,600 lbs." The product guides and installation manuals give a weight for each gate length; the table shows both as printed.

Usage class
Which usage class is it listed for?
The CSL24UL installation manual defines four usage classes. Class I is "intended for use in garages or parking areas associated with a residence of one-to four single families." Class II is "intended for use in a commercial location or building such as a multi-family housing unit (five or more single family units), hotel, garages, retail store, or other buildings accessible by or servicing the general public."
The two documents differ for three models: the LA400 manual lists Class I, II, & III, and the RSW12UL and RSL12UL manuals list Class I & II, while the 12/21 product guides for all three list I, II, III and IV.

Power
How is it powered?
The chart gives each model's standard power, battery backup cycles and solar cycles per day. Its footnote says cycles marked * are for Zone 1 with a 10W solar panel (6 hours sunlight per day), and cycles marked ** are for Zone 1 with a 20W solar panel.
On batteries, the LA500 manual's accessories list says: "Two identical 12 Vdc batteries are required for each gate operator. Do not mix 7AH and 33AH batteries within a gate operator."
The documents disagree on solar for the two industrial slide models. The chart lists about 20 cycles a day for the INSL24UL with a 20W panel and "Not Recommended" for the IHSL24UL. Their shared product guide, dated 5/22, says "Note: Not recommended for solar applications.", and both models' data sheets, also dated 5/22, list "Solar-Power Capabilities Yes".
The CSL24UL product guide describes two behaviors in LiftMaster's words. Under the heading Fire Department Compliance: "Allows gate to auto-open upon loss of AC power or battery depletion." Under Manual Disconnect: "When unlocked allows gate to be opened manually."
| Model | Standard power | Battery backup | Solar cycles per day |
|---|---|---|---|
| LA400PKGUL | 115V Single Phase [LA400UL data sheet, 12/21: 120/230VAC single phase] | 400 cycles | Approx. 81 cycles* |

Safety
What safety devices does LiftMaster say a gate needs?
LiftMaster's CSW24UL product page says the operator is "Tested to the most stringent UL 325 industry guidelines" and that external entrapment protection devices are needed "to meet UL 325 standards". It adds: "Your Installer will recommend suitable entrapment protection devices for your installation, such as photoelectric or edge sensors."
The CSL24UL manual's cover adds: "This model is for use on vehicular passage gates ONLY and not intended for use on pedestrian passage gates." Its requirements read: "A minimum of two independent monitored entrapment protection devices are required to be installed at each entrapment zone." and "It is the responsibility of the installer to install external monitored entrapment protection devices for each entrapment zone." On gate construction it says: "Vehicular gates should be installed in accordance with ASTM F2200: Standard Specification for Automated Vehicular Gate Construction."
The same manual's list for end users includes: "Contact a trained gate systems technician to maintain and repair the gate system (End users should never attempt to repair the gate system)." and "Discontinue use if safety systems operate improperly, the gate is damaged, or the gate is difficult to move."
Two manuals word the direction rule differently. The CSL24UL manual says: "The operator will only operate with a minimum of two independent monitored entrapment protection devices installed in each direction; two in the open direction and two in the closed direction." The LA500 swing manual says: "The operator will only operate with a minimum of two independent monitored entrapment protection devices installed in either the open or closed direction."
The table lists the safety and detection devices LiftMaster's documents name.

Keypads
The KPW250, KPW5, KPR2000 and SRDRKP keypads
This page covers four LiftMaster keypads: two wireless keypads, a wired keypad and proximity card reader, and the keypad model of LiftMaster's Smart Readers. The table gives each one's capacity, power and connection.
The KPW instructions say the keypads "are security keypads and should be programmed to ONE operator." They have sections headed Basic Programming, Program to Operator and Additional Programming. This page does not reproduce programming steps or codes.
On placement, the instructions state: "User activation controls MUST be located at least 6 feet (1.8 m) away from ANY moving part of the gate and where the user cannot reach over, under, around or through the gate to operate the controls."
For LiftMaster's video intercoms, see Elwin's comparison of DoorKing and LiftMaster telephone entry.
| Keypad | Type | Users or PINs | Power | Range and connection |
|---|---|---|---|---|
| KPW250 | Wireless commercial keypad | Up to 250 permanent 4-digit PINs; up to 10 unique temporary PINs | 9V lithium battery, life up to 5 years (based on 25 activations per day) | Up to 500 feet in an open field; programmable to 1 LiftMaster gate operator or commercial door operator |

Connectivity
Does it work with myQ?
The feature chart's "myQ Enabled" row reads Yes for each of the 13 models. LiftMaster says myQ technology enables you to securely control and monitor your gate operator from anywhere, with the footnote "Cellular data or Wi-Fi connection required. Test equipment regularly and follow safety instructions."
The connection runs through a separate device, the 828LM Internet Gateway, which "connects myQ-enabled gate operators to the Internet and enables control through the myQ App." The LA500 manual marks the gateway as not provided, and the INSL24UL product page says monitoring and control with myQ "requires additional Internet Gateway unit".

Manuals
Where are the manuals?
Each product page links one English installation manual, except the LA412UL page, which links a wiring diagram and an addendum under Manual instead. The table gives each manual's number and back-cover copyright year and any label the product page puts on it.
The manuals address the installer. The CSL24UL manual runs from safety and installation through adjustment, programming and troubleshooting, with a diagnostic codes table, to a safety checklist, and it says: "DO NOT attempt repair or service of your gate operator unless you are an Authorized Gate Systems Technician." This page does not reproduce the manual's programming and adjustment sections.
The CSW24UL product page also links a troubleshooting guide labelled "Models manufactured after 2022", whose cover reads "TROUBLESHOOTING GUIDE for 2022 UL 325 Compliant Gate Operators". Its cover note on the models it does not include is quoted with the manuals table.

FAQ
LiftMaster gate operator questions
Is a LiftMaster gate opener the same as a LiftMaster garage door opener?
LiftMaster's site lists garage door openers and gate operators as separate entries, and this page covers gate operators only.
How heavy a gate can a LiftMaster CSW24UL move?
LiftMaster's feature chart lists 1,600 lbs. and 18 ft. as separate maximums. By gate length, the product guide runs from 1,600 lbs. at 8 ft. to 600 lbs. at 18 ft.; the swing gate table gives every point in the guide and the 2018 manual.
Where are the programming steps for a LiftMaster gate keypad?
LiftMaster's instructions for its two wireless keypads have sections headed Basic Programming, Program to Operator and Additional Programming. This page does not reproduce programming steps or codes.
