Introduction
The R915 is a weatherproof 4-wire proximity card reader with a built-in
backlit 12-button keypad for PIN entry. The R915 is compatible with any
Digiplex or EVO control panel and is connected to a ACM12 using only 4
wires to facilitate installation.
Keypad
This reader can use both the Card and PIN functions. However, the PIN must
be entered after the card is scanned if Card and PIN is enabled. You can also
use the Card Only, PIN Only or Card or PIN settings, which are set in the
ACM12. PIN settings are only available with ACM12 V4.0 or higher. The
key is used to cancel a PIN entry, the key is used when using Flexible Code
Length and entering a code shorter than 6 digits.
Arming and Disarming
It is currently possible to arm and disarm the system if the proper options are
enabled in the User and door’s settings. Refer to your EVO programming
guide for additional information.
Tricolour LED Display
The reader includes a tricolour LED display (red, green and amber) that is
used to indicate system status as shown in the LED display table.
Audible Tone
The reader includes a built in beeper.
Weather Resistant
The rubber gasket and plastic PCB cover allows you to mount your R915
indoors or outdoors.
Technical Specifications
All specifications are subject to change without notice.
Installation
Mounting
Mount the reader on a clean, flat and even surface to avoid bending the
plastic casing. Once mounted, properly seal the reader’s contour to avoid
possible water infiltration.
It is highly recommended to mount the reader on a flat, even sur-
face, thereby making it less vulnerable to weather damage. If
mounting on an uneven surface is absolutely necessary, ensure
that all gaps between the reader and surface are properly
sealed.
Mounting on Metal
Metal may decrease the read range. The card reader can be mounted on
metal but do not surround it by metal. If the reader must be installed in a
metal enclosure, ensure that the face of the card reader is not covered and
that there is at least 4cm (1.6") between the card reader and the metal on all
sides.
Connection
Connect the R915 as shown in Figure 1.
