Remote tone activation can be accomplished by wiring a switch to the printed wiring
board connector (J4), between the GND and desired tone (WAIL, YELP, HORN) terminal(s).
(See figure 2.) The remote switch and wiring method shall comply with all National and Local
Electrical Codes.
The remote switch and wiring method need to comply with all National and Local
Electrical Codes.
Use an appropriately sized shielded twisted pair of wires. For proper operation of the
remote activating circuit, the total loop resistance (resistance of GND wire plus resistance of
tone terminal wire plus dry contact resistance) should not exceed 1000 ohms.
Strip no more than 0.25-inch (6mm) of wire insulation from the ends of the leads to
connect the remotely located tone activating dry contact terminals between the GND and
WAIL, YELP, or HORN terminals of the four-position connector plug supplied with the unit.
Make sure the lead insulation is flush with the connector. If stranded wire is used, be sure that
there are no loose strands outside the connector plug.
Plug the connector into the receptacle J4 on the printed circuit board.
The selected tone will play when the unit is powered up and remote activation contacts
are closed.
By connecting a dry set of contacts to each of the three tones, any single tone can be
activated by closing the appropriate contact. When contact closures are applied to all tone
terminals simultaneously, the HORN tone will override the other two tones. If contact closures
are applied to HORN and any other tone, HORN will override the other tone. If contact
closures are applied to both the WAIL and YELP tones, the WAIL tone will override the YELP
tone.
2. Wiring for Single Tone Activation at Power-Up
Make sure that the power source to the unit is off.
By connecting a permanent short wire jumper between the GND terminal and desired
tone terminal, the unit can be operated by switching the operating power.
Connect a short [1-inch (25mm) long, #22 AWG (0.33mm2)] wire between GND and the
desired tone terminal of the four-position connector plug. (See figure 2.)
Plug the connector into the receptacle J4 on the printed circuit board.
Switching ON the operating power will now activate the unit.
Property damage, serious injury, or death could occur if the housing is not closed
properly. To reduce possibility of explosion, housing cover must be kept tight while
circuits are energized.
