DSC Wireless Keys and Personal Panic
Provide users with a sense of control over their security
systems and the added confidence that comes with
portable personal protection. These multipurpose wireless
devices give users a means to arm/disarm their DSC security
systems from a distance or call for help from anywhere inside
the home. DSC is committed to reducing false alarms and has
incorporated activation delays into its wireless keys that
▼
require users to press and hold a button for a period of time
before its function is activated. A red LED indicator located on
the devices flashes to indicate that a transmission has been
sent to the security system. Built with reliable 433 MHz
technology and powered by long-life lithium batteries, DSC
wireless keys use the latest production techniques to
incorporate practical features and benefits into a design that
is sleek and user-friendly.

DSC Wireless Keys and Personal Panic
WS4938 1-Button Personal Panic
The WS4938 1-button personal panic provides users with an
uncomplicated, portable means to call for help from anywhere
inside the home. The device’s large panic button is clearly defined
to ensure trouble-free activation in times of emergency. The panic
button incorporates a full two-second delay to help reduce false
alarms and to ensure transmissions are sent to the security system
only when intended.
The WS4938 is water resistant, includes a neck strap and a
multifunction clip that can be permanently mounted to a convenient
location or clipped to a belt. The WS4938 is a supervised unit that
sends periodic transmissions to the receiver to indicate functionality
and battery status. If a transmission fails to reach the receiver after
a programmed length of time, a trouble is indicated at the
control panel keypad.

Ideal for large residential or small commercial
applications, the WS4959 is capable of supporting 12

independently controlling up to three partitions.
