RCI Introduces DE8310 Delayed Egress And EW8310 Early Warning Electromagnetic Locking systems

Some locksmiths prefer to not use electromagnetic locks. They prefer conventional latching hardware, preferably without any wires. This philosophy puts them at a severe disadvantage with the rest of the industry, and with clients who know about electromagnetic locks, and demand them. Part...

A magnetic lock might be a “Listed Auxiliary Lock.” A maglock may be listed as a “burglary resistant electric lock.” Some maglocks are recognized as a component of a delayed exit system, listed as part of a delayed exit system and as part of a free exit system; and listed for use on fire doors. The listing needs to be consistent with how a product is used in order for it to make any sense...

A ridiculous but true example of deceptive labeling was a security device I knew of (which will remain unnamed), that was advertised as “UL Listed.” Unfortunately, the only part of the product that was ever tested by UL was its line cord.

“Recognized” is the status UL grants to a component. A “Listed” device is complete in some sense but a “Recognized” component needs to be combined with other components to create a finished product.

“Certified” means a product that has been successfully tested by UL to a non UL standard. This is most often an ANSI standard. The ANSI magnetic lock standard was published around 1991 and it included some performance grades. Although LAHJ’s don’t demand that an ANSI locks be supplied, they’re interested in UL safety testing. Manufacturers use ANSI compliance to compete with each other since it is a recognized and respected performance-oriented standard.

With all the fine print, it is easy to understand the confusion. But the answer is clear. Use equipment from established manufacturers, stay up to date with local building codes and preferred practices, and design your systems with safety foremost in your mind.

RCI DELAYED EGRESS SYSTEM

Rutherford Controls (RCI) offers a complete delayed egress system that includes the EW8310 Early Warning Lock; DE8310 Delayed Egress Lock & 10-5 / 10-5-PDD-FT Power Supply.

This power supply and extensive selection of option modules offers all the features and options required to form the backbone of just about any electric door control system, especially those incorporating electromagnetic locks.

The Delayed Egress Electromagnetic Lock is an All-in-One delayed egress system with a built-in sensor that detects pressure applied to outward swinging doors. Built-in sounder, voice and CCTV monitoring combinations make this ideal for applications requiring Loss Prevention, Life Safety and Traffic Control. The DE8310 is unique in that there is no need to replace existing door hardware making this an easy and affordable delayed egress solution.

The system has the following certifications:

10-5 – [UL Listed] (Power Supply Only)
10-5-PDD-FT – [ UL Listed] (Power Distribution Device - Fire Trigger)

Standard features include:

The panel door is a drop down lid designed with the installer in mind. It provides a usable work surface, along with a 110 VAC receptacle for installation and maintenance convenience.

The Class 2 Rated Power Limited low voltage output is determined to be safe for use by installers where permitted by local code

The output is field selectable (12VDC@5AMP, 24VDC@3AMP)

The Auto-Sensing AC Input will accept an input of 90 - 250VAC. This means the 10-5 remains very stable during fluctuations in local power

The built-In 110VAC receptacle can be used to power drills or soldering irons for installation purposes or for service assistance. The drop down lid becomes a convenient surface for test equipment .

The AC Fail Monitoring Relay can be used to send a signal to an external monitoring panel or guard station to indicate that the AC power to the panel has been interrupted. It can also be used to signal fire panel distribution board of AC fail to meet NFPA-101 Life Safety standards.

The Battery Monitoring Relay can be used to send a signal to an external monitoring panel or guard station to indicate that the backup battery is not connected or is no longer holding a charge

The Listed Subassembly Modular Output Board means that the zone output and fire disconnect boards can be added or removed from the 10-5 as required without affecting the UL listing.

The Fire Panel Disconnect Board is connected to the local fire alarm panel to drop power to all electromagnetic locks as required by most local building and NFPA-101 Standards.

The Power Distribution Board with Supervised Interface is used to convert a DC power source into eight class II power limited outputs (that can be controlled by a fire alarm control panel.) Each output can be selectively set to turn ON, OFF or remain unchanged when the fire alarm control panel triggers the board, allowing the installer to power multiple devices with the same power supply.
