rAdio sirEn trAnsmittEr
the Ness radio siren transmitter (rst) is
purpose designed to send a variety of alarm
signals to the rsI and rss radio sirens.
the rst is a miniature transmitter board with
flying leads fitted allowing it to be easily connected
to a control panel.
INPuts
12V +/- wires: Constant 12VDC input.
Input 1 - White: sends oN signal or aux signal
depending on the setting of LINK 1.
Input 2 - Blue: sends PaNIC signal or oN signal
depending on the setting of LINK 1.
LearN MessaGe
the rst sends a learn message when power
is applied.

The Rss strobe output will still turn on but it
will reset after 5 minutes along with the siren
output.

Link 1 is off for negative trigger
A 2K2 resistor is required 12v and REsET- if a 12v Piezo siren is
also connected to the REsET output. The resistor can be omitted if the RsT
is the only device on the REsET output.
