Optional features
Tamper – Enabled by default and activated when the mounting plate is removed. The tamper is normally closed
and changes to open circuit between Tamper 1 and Tamper 2 control lines. Tamper 1 and Tamper 2 control lines are
interchangeable. Either of these lines can be connected with the reader ground line to reduce the number of cable cores
required in the reader cable. Tamper 1 and Tamper 2 are rated 0–12VDC at 100mA.
Hold Input – When asserted, this line either buffers a card (default) or disables a card read until released, as configured.

HID Signo™ Reader Installation Guide
CAUTION: Install the reader on a
flat, stable surface. Failure to do
so may compromise the IP rating
and/or tamper feature. If mounting
on or near metal, a spacer is
recommended for optimal read
performance. Refer to the Readers
and Credentials How to Order Guide
(PLT-02630) for available options
and part numbers.
CAUTION: Use the supplied
screws to ensure correct fitting
and to avoid damaging the reader
or mounting plate. HID is not
responsible for damage due to use
of unapproved mounting hardware.
