Here
are some of the features that make the AP501 such a robust door lock.
- The
AP501 is constructed mostly of metal, in both interior and exterior units. Even
the keypad cover, battery compartment cover and the Open/Close button are made
of metal. No wonder it weighs 6 pounds, 2 to 4 times the weight of most other
deadbolt locks! The three main components of the exterior unit are designed to
withstand hammering.
- The
Tag Key sensor, temporary power terminal, and the keypad are supported by metal
or hard-rubber parts so that any impact on them is born by a 2.5-mm thick metal
mounting plate as well as the door surface, thus protecting the circuitry in the
exterior unit. Smashing any of these components will not automatically yield access
to the intruder.
- The
exterior mounting plate blocks access to the deadbolt latch even if the exterior
unit is broken off thus preventing the intruder from unlocking the lock. Most
conventional deadbolt locks would immediately expose the deadbolt latch if the
exterior unit is broken off, allowing the intruder to manually retract the deadbolt
latch and gain access.
- The
1-inch throwbolt is fortified with a 5-mm thick carbon rod that resists sawing.
The opening between the exterior unit and the interior unit (through which the
connection cable passes) is small and covered so that hot or cold air from the
outside is not allowed to enter the interior unit thus minimizing condensation.
- Although water-proof,
any moisture that still enters the exterior unit or from condensation is allowed
to flow down through the weep holes. The weep holes are partially blocked by the
mounting plate to prevent abuse.
- On
the interior unit, the battery compartment cover is fastened with a screw so that
the batteries do not accidentally fall out if the door is slammed shut. It also
has rubber pads to secure the batteries in place.
- The
manual override button directly operates the deadbolt latch. It has no intervening
parts other than a directly-connected rotary bar made of metal, so that just about
under all circumstances you will be able to open the door from the inside.
- The
vital parts of the lock such as the CPU, PCB, batteries, motor, deadbolt latch
drive mechanism, etc., are located in the interior unit on the secure side of
the door and are further protected by a heavy-duty interior mounting plate that
disallows any access to the vital parts.
- The
AP501 has a bypass circuitry that protects the PCB in case of a high-voltage attack
so that the lock remains locked.
