By looking at the overall cost of ownership the District has been able to standardize on products that have proved to be dependable and long-lived while still maintaining a competitive bid process for the hardware. Peterson adds, “We just don’t have time to learn about every possible type of hardware and stock spare parts for them all. In the field, our technicians can perform any needed service or repair without going back for parts.”
Moving from basic door hardware into electronics, the District confirmed the wisdom of specifying on overall value rather than price alone. “We started out looking at the least costly products to get the job done, and it didn’t work out. We found we had to go back time after time to adjust or replace them,” says Foreman, Safety Systems/Police Electronics, JonScott Fasselin.
Exit devices are a critical part of the system, and the District now uses Von Duprin 99 or 33 Series devices in most applications. One feature that has saved time and expense is the availability of an electric latch (EL) kit to upgrade mechanical exit devices when moving into electronic access control. Instead of replacing the entire device, the installing technician can simply install the kit and wire the device.
“Their design saves us a lot of time because we can cut the devices to length. With some of our older buildings, there was no standard for door sizes, so when we need to replace an old device, we can just take a 36 inch and cut it to 30 inches or whatever size we need. That way we don’t have to carry a lot of different sizes on our trucks or go back to the shop for another size device,” Technician Tom Penney says.
Granite School District also uses Von Duprin power supplies and EPT power transfers, which route the power for the EL devices from the frame to the door. Peterson says door loops are often used on existing applications, but on any new construction, the doors and frames are prepped for the power transfers.
LCN Auto Operators are used where ADA accessibility requirements must be met, although Peterson says they are not specifically required by Utah law. Instead of integrating them into the access control system, they generally are used on the main door that is left unlocked during normal hours.
In one case, to meet the needs of the District’s Young Parents Program, the operator can be controlled by an access card outside of normal hours. Most of the time, the parent pushes a button, and the office staff activates the door operator to let them in. The door is monitored by an intercom and camera for identification. Peterson explains that the door operator makes it easier for parents with strollers or small children.
In many cases, card readers are mounted directly on the door they control, rather than on the frame or adjacent wall. “Instead of wiring through the mullion or frame, we just drill another hole in the door a little bit above where we pull the wires for the exit device. It’s a lot easier, especially with existing construction where the jambs are filled with concrete and we have to drill through it,” Penney explains, adding that having the reader on the door makes it easy for the user to know which door to open when there is a pair of doors.
To maintain a competitive bidding environment, the District sends RFPs to hardware distributors who bid on providing the door and access control hardware and service under a one-year contract with an option to renew for three years. On new construction, the hardware is purchased through the contracted distributor, rather than as a part of the building contract. The building contractor simply provides the doors and frames with the proper prep for the hardware designated by the District.
The District continues to refine its approach to security as needs and available solutions change. One possibility recently under discussion is the use of wireless locks on portable classroom buildings to provide security without the need for continual rewiring.
