Slim Fit & Monitored Electric Strikes Provide Unique Benefits

Providing door opening solutions for applications where there are unique safety requirements and where security considerations can be a challenge.

Here, Andy Stolworthy, Product Manager for Adams Rite, discusses how using slim fit and monitored electric strikes can deliver significant benefits to commercial applications.

Generally used to secure schools, commercial units and retail outlets like shop fronts and department stores, electric strikes are an effective way of maintaining the required accessibility, while also delivering a high level of functionality and durability.

Slim fit electric strikes

Where a single aluminium door is located next to a glass panel on a shop front, aluminium door manufacturers have re-designed their systems to combine the door panel and the glazing panel surround into one section, in order to reduce cost and improve aesthetics.  It is here that a slimmer electric strike comes in to it’s own.

The single section can have implications as the space previously available to install the hardware is now shared with the glazing.  Here the reduced depth of a slim fit electric strike allows both the standard glazing and section to be used without compromising on performance.

Adams Rite’s Ultraline 7400 is an example of a slim fit electric strike that is built to be both robust and durable for areas that experience high levels of traffic.

The 7400 will operate a door with a side pressure of up to 15kg.  Pressure often builds up due to poorly fitted hardware, door misalignment or the effects of air-conditioning and can be enough to stop many common electric strikes from operating.  By using the 7400, time and money can be saved on unnecessary call-outs.

Assisting in complying with Approved Document M of the Building Regulations relating to disabled access, the 7400 requires half the opening force of the previous 7100 model.

A holding force of 1080kg, the ability to be set as either fail safe or fail secure and a multi-voltage solenoid make the 7400 one of the most versatile products on the market.

Monitored electric strikes

There are a number of products on the market that offer either solenoid or latch monitoring as a means of protecting against accidental security breaches when doors remain slightly ajar, or when there is an attempted break-in.

Ideal for use on buildings when there are a lot of external doors, monitoring the solenoid and latch of an electric strike allows a facilities manager to be aware of which doors are locked and, more importantly, which aren’t.

An example of a monitored electric strike is the Adams Rite 7400M.  Effectively the monitored version of the 7400, the 7400M shares all of the features and benefits with the added functionality of latch and solenoid monitoring.  Where previously latch and solenoid monitoring was offered individually, this double monitoring is now set as standard, helping to keep things simple for both the installer and end user and provide greater value for money.

Like the 7400, there is the option of alternating between fail safe and fail secure using a switch that is located on the strike body.  Tested to 500,000 cycles, the 7400M operates with an innovative split jaw design that offers increased reliability and durability.

Both the 7400 and 7400M are dual voltage AC/DC using either 12 or 24V.


As with any type of door solution, it is important to specify the right hardware to the appropriate application, and in doing so look at all of the available innovations that may benefit the project.

Using slim fit and monitored electric strikes can solve common onsite problems for the end user, improve customer satisfaction rates and help installers deliver a more efficient and cost effective service.
