The Ness SCR+ Flexible Standalone Receiver
is a unique high performance radio receiver
designed to operate with any Ness proprietary
radio transmitting device including Ness
Radio Keys, Radio Key pendants, Radio Reed
switches, Radio Smoke Detectors and Radio
PIRs.
The SCR+ is ideal for connecting to alarm
panels which do not provide a wireless facility
and can be used for connecting wireless
devices for zone alarms, Panic buttons or Radio
Keys for Arming and Disarming the Panel.
The Inhibit input gives the receiver the unique
ability to identify the Armed/Disarmed status of
an alarm panel. When used with a Ness radio
key it allows the receiver to always correctly
Arm or Disarm the Panel.
The SCR+ is also ideally suited for applications
that require a remotely switched relay output for
low voltage switching applications e.g. garage
door opening.
The Relay output can be selected to be Pulsing
or Latched for alarm signals or a Pulsing output
for Panic/Tamper, Aux or Low Batt signals.
The SCR+ will accept up to four individual
Radio Keys and Panic Buttons or up to four
alarm transmitting devices (Radio Reed
Switches or PIRs).

The relay output can be programmed
to provide an On/Off/Alarm output or it can
duplicate one of the open-collector outputs.
