Power Source Requirements
The Cheetah SE Reader requires nominally 12 VDC at 1 Amp to operate correctly. The power source can be from the power
supply on the PACS or can be a separate local supply. The reader must be powered by a compatible UL listed access
control panel or a UL294 listed power supply.
CAUTION
: If you are using a separate local power supply, ensure that the ground of the local supply connects to the ground of the
PACS. The local power supply must be a UL listed access control power source. UL 1076 burglar installations require UL 603 listed
power supply with minimum 4 hours standby power.
Power Wiring
The wiring to deliver power to the reader should conform to proper electrical installation practices and codes, and should
be of a gauge required to deliver the required voltage and current to the reader without excessive loss or heating.
Wiring methods shall be in accordance with the National Electrical Code ANSI/NFPA 70 or CSAC22.1-02 – Canadian
Electrical Code, Part 1, Safety Standard for Electrical Installations.
The recommended power wiring is Belden #8461/8442 twisted pair. The maximum length depends on the wire gauge.
Installation
This section contains the instructions for wiring the readers and mounting the reader on a wall or similar support.
Reader Dimensions

shows the physical dimensions of the Cheetah SE readers. The dimensions of the contactless reader are
the same as the contact models, except that the contact models have a card insertion slot at the bottom and the contactless
models have no slot and have eliminated the recess for that slot.

Pre-Installation Checks
Site
■ Check power, wiring,
equipment clearances, and
code compliance at the site.
■ Ensure that the mounting site
is ready by verifying that:
• the site has been approved
and all wiring complies
with UL requirements and
other codes, as appropriate.
• all preliminary site work is
complete, and the site is clean and free of dust or other contaminants.
• an appropriate power supply is accessible.
• the reader operating temperature is 14°F (-10°C) to 150.8°F (66°C).
■ When installing the reader, use anchoring systems capable of sustaining a load of at least 25 lb.
