UL Requirements
The 2000e/2000eM keypad is a UL Listed access control unit. This
section contains information regarding the requirements necessary
to meet UL compliance.
Wiring methods shall be in accordance with the National Electrical
Code (ANSI/NFPA70), local codes, and the authorities having
jurisdiction.
All wires and cables used must be a minimum of 22 AWG,
stranded and shielded UL Listed and/or recognized wire suitable
for the application. In addition, input and output cables that extend
from the unit must be shielded, twisted pair. Ground the shield
only at one end, usually the circuit end.
All interconnecting devices (ie. door contacts, REX, locking
devices, alarm devices, doorbell, etc.) must be UL Listed.
A UL Listed access control power limited power supply, capable
of 4 hours standby, must be used to power the keypad.
A minimum of three user codes must be programmed for
controlling access.
The following Wiegand card formats were not evaluated by UL:
28-bit, 29-bit, 30-bit, 31-bit, 32-bit or 36-bit (formats 2-8 from
wiegand format chart. UL did evaluate the 26-bit card format
(format 1).
8-Bit Burst Mode was not evaluated by UL.
Installing a Tamper Switch
To meet UL requirements, a UL Listed tamper switch must be
installed in a UL Listed single-gang box used for mounting the
keypad. The tamper switch must activate if the keypad is
removed from the box and must disconnect power from the lock.
The lock must be a fail-secure device, meaning the lock remains
locked when power is removed.
In addition, once the tamper device is activated, it must be
configured so that it can only be reset from within the protected
area. Only a Sentrol 3012 or Sentrol 3025T tamper switch can be
used. The diagrams below show the suggested mounting location
for each device.
