c. Run wires from the signal source through conduit to the 300TAR. Pass the signal line
input leads through the hole in the housing .
d. Connect the connector card’s signal high wire to the high side of the signal line input and
connect signal low wire to the low (common) side of the signal line input, as described in
the appropriate SelecTone Command Manual. For the 300CK connector card, refer to
Federal Signal Part No. 2561044 or 2561090 (Model 300VSC-1 or 300SCW-1
SelecTone Command). For the 300CKS connector card, refer to Federal Signal Part No.
255A204 (Model 300SSC Supervised SelecTone Command). For the AM25CK,
AM70CK and AM100CK, refer to the instructions packed with each unit.
2. Power Connection.
All power wiring to the Model 300TAR must be routed through liquid tight conduit fittings
approved for NEMA4X installation. Run electrical wiring from the power source through
the conduit to the 300TAR power input plug at location J1 following National Electrical
Code recommendations for watertight installation. Plug unused conduit opening with plug
using thread sealing compound or tape to form liquid tight seal.
WARNING
To avoid electrical shock, do not connect wires when power is applied.
a. 24VAC/VDC.
The Model 300TAR can be operated from a 24VAC or 24VDC source. Connect the red
(+) or AC line (hot) lead of the power source to the +24 VDC terminal of connector plug
via a user supplied 1/
2
amp fuse and the black (-) or neutral AC lead of the power source
to the -24 VDC terminal of the connector plug at receptacle J1.
b. 120/240VAC.
Set the voltage selector slide switch to the desired operating source voltage. Connect the
AC power source to the AC terminals of the power input plug.
3. Relay Output.
The relay has double pole double throw contacts. These contacts are accessed via terminal
plug P4 at receptacle J. Each set of contacts can switch up to 8 amps resistive load at
30VDC or 250VAC. The load connected across these contacts should be adequately fused
by the user supplied fuse. If the relay contacts are used to switch inductive loads, they
should be appropriately derated. For inductive load of a 0.6 power factor the contacts can
switch up to 4 amps at 30VDC-or 250VAC.
IV. OPERATION.
The relay can be energized by any audio tone signal of frequency from 470 Hz to 1300 Hz.
It can also be activated by a voice band audio signal. The unit is shipped with the frequency POT
R9 adjusted to activate the relay at 470Hz. To use 300TAR as a tone activated relay, set jumper J3
to TONE mode. Make signal line and power connection as described above.
Turn power to the unit on. Apply desired tone signal to the input at J2 via connector card. If the
relay is to be activated by a signal frequency other then 470Hz, turn the Tuning potentiometer R9
very slowly clockwise with a thin blade small screw driver while observing the Red LED located
next to the relay. Stop turning the pot when the Red LED turns on. The ON state of the LED
indicates the relay has been activated.
The relay will stay on as long as the signal of tuned frequency is present at the input. Remove the
signal from the input and the relay and Red LED will reset after a predetermined delay. This relay
dropout delay time can be adjusted from 5 sec. to 75 sec. by adjusting the delay control POT R17.
The 300TAR can be configured to be activated by tone or voice applied at the signal input. To
operate the unit in this mode locate the mode selector jumper J3 to PA position. Apply voice or
