Low-energy door operators are a great product for locksmiths and other security professional to provide. They are used in new construction as well as frequently called for in retrofit situations, and are used primarily with swinging doors. I’ve had the opportunity to troubleshoot...

Ingersoll Rand Security Technologies has introduced a new and improved LCN Benchmark Automatic Operator that comes equipped with many new standard features and adjustments, such as intelligent Power Boost and Push-N-Go.
The Power Boost feature on the new Benchmark operator provides it with the extra strength needed in the last 10 degrees of closing to securely close and latch the door. As a result, wind, HVAC and other forces will not prevent the door from latching and users can be assured that the door is secure.
Another new feature is Push-N-Go, in which the door automatically opens when it is manually pushed beyond 3 degrees. This is an important attribute, especially for assisted living centers, hospitals and facilities used by younger children who may need help when opening a door. If this feature is not needed in the application, users can turn Push-N-Go off.
The new Benchmark’s control box includes clearly labeled adjustment pods, which make set up and fine-tuning easier than ever. Oftentimes, different applications require different speeds and features. With the new Benchmark, they can be adjusted in seconds. The clear labeling means a lost instruction manual is no longer the problem it used to be.
We interviewed Joseph Vaida, product manager for Electronic Door Controls at Ingersoll Rand Security Technologies, to help us all to better understand this product and how it will fit into the low-energy door market. Here are our questions and Vaida’s answers.
What is the M.S.R.P. ?
$2,426 is the list price.
What is the warranty?
How many components is the unit comprised of? That is; are there a separate motor, controller and power supply, which can be serviced individually? (I asked this because one low-energy operator from another vendor we’ve used in the past is a one-piece system, and if it fails, it stops being a door operator and turns into a door stop)
The Benchmark is comprised of a standalone control box (1 piece), a motor/gear box assembly (1 piece), mounting bracket, two end caps for the header, a cover and arm assembly.
Can the unit be applied to either the push side or pull side of the door? (We’ve had situations where we’ve been shipped the wrong hand motor or controller and its cost us lost time)
Can the unit be applied to the exterior of a building?
Yes. The Benchmark Unit is electro-mechanical, and designed for light – moderate traffic, that will mostly be using the door automatically. Although it is designed for these applications, it has been aggressively tested to ensure quality in most applications.
Some low-energy units have limitations with respect to duty cycle and door weight. Does yours?
The Benchmark unit has been internally tested to over 3 million cycles. Per the installation instructions, it’s suggested to contact technical service when using on a door over the weight of 200lbs. Further details are needed on the application to ensure that it’s the correct operator for the application.
Is an external delay module required for use with electric locking devices?
No. There is a delay activation option that can be turned on as well as a 24 volt DC output from the onboard power supply to power the locking device. This operator can be attached to an electric locking device. Failsafe or fail secure systems to suit magnetic locking systems or electric release strikes.
Are there terminal points on the unit for use with external safety and presence sensors and knowing act controls?
Yes. The safety circuit assumes two different functions, depending on which segment of the cycle is in operation. If the safety circuit is operated before the door is activated it will prevent the door from opening, or it will hold the door open if it is in the open position.
Is it difficult to coordinate two units of these on a pair of doors?
No. It will work with optional wireless sequencer that is very user friendly or be hard wired with a sequencer.
(Locksmith Ledger meant a pair of doors not two pairs of doors in a vestibule, but the dashboard on the Benchmark is simple, so matching them up should be a snap.)
The unit is designed to mount entirely on the header?
Yes. The Benchmark is available with a header length from 27” up to 49” for a single door. The customer can order specific lengths to fit their header. Further details are listed in the installation instructions.
How does the unit close the door? Is it a motor, a conventional door closer or a spring?
Spring closes the door under controlled conditions, because the system utilizes regenerative braking control for the closing speed on the door. If required because of unequal pressure that does not allow the door to close under normal force, a power boost option can be activated that will drive the door closed using the motor.
What if there is a power failure?
During a power failure, the door will function as a manual closer, utilizing regenerative braking control for its closing speed. When power is restored, the controller settings remain as set by the customer; there is no need for resetting.
The door must be essentially flush with the header? What if it isn’t, like if you’re mounting on the push side?
That will not impact operation as long as the unit is set up per the instruction if special needs are required then customer service can assist in installation.
With extra effort and training, locksmiths can become accessibility and security experts.
This certification enhances the locksmith’s image as a security professional and provides another tool for winning future door operator business.
