GTS

An electronic cylindrical lock replaces or supplements a mechanical key cylinder with a built-in reader and controller that grants access via credentials like RFID cards, smartphones, or PIN codes. PDQ's GTS is built on the Grade 1 GT Series cylindrical chassis and adds Bluetooth Low Energy connectivity, AES 256 encryption, and event logging, while keeping a mechanical key override for backup entry.

The GTS runs on four standard AA alkaline batteries for approximately two years of typical use, with a low-battery alert that warns administrators before it dies. For continuous-power installations instead of batteries, PDQ also offers an optional 5V DC power supply.

No. GTS operates as a standalone lock over Bluetooth Low Energy (BLE 4.2/5.2) with no wiring required, and it can also run in an online mode for networked management when a facility wants centralized control. Either way, there's no home-run wiring back to a panel.

GTS is built on PDQ's GT Series Grade 1 cylindrical chassis, ANSI/BHMA's highest commercial durability rating, which suits high-cycle doors such as classrooms, office suites, and busy commercial entries. It also carries a UL 10C 45-minute fire rating and a 25-year mechanical warranty (2-year electronics).

GTS accepts RFID cards/fobs, Bluetooth smartphone credentials, PIN codes, and a mechanical key override, so a facility can standardize on one credential type or mix them by user group. It supports MIFARE DESFire EV1/EV2/EV3/Light and MIFARE Ultralight formats, plus optional Prox compatibility for facilities migrating off legacy card systems.

Yes, GTS includes a local-activated lockdown function that immediately secures the door without needing a networked panel to trigger it, useful for active-threat situations. It also supports scheduled access windows, auto lock/unlock, and a do-not-disturb mode for everyday access control beyond emergency use.
