Common questions about manuals, registration, and support for this brand.
To determine the hand of the door, stand on the outside (secure side). If the hinges are on the left, it is a Left Hand (LH) door. If the hinges are on the right, it is a Right Hand (RH) door. Reverse bevels apply if the door swings towards you.
Most PDQ electronic locks, such as the GTS and MRS series, are designed to use standard non-rechargeable alkaline batteries for optimal performance.
A UL 294-rated power supply providing a minimum of 1 Amp at 24VDC (+/-10%) is required. It must also be connected to the fire alarm system to cut power in an emergency.
Handing adjustments often involve rotating the chassis or rose plate. For specific models like the GTS Cylindrical Lock, you may need to remove the rose plate, unplug the motor connector, rotate the chassis 180 degrees, and reconnect the motor before reassembling.
