AUXILIARY INPUT

During installation an auxiliary input may be connected to the horn ring or other switching device. It provides the same operation as pressing the Horn button or optionally the Manual button.

See OPTION SWITCHES section for further details.

CUTOUT INPUT

During installation, a cutout input may be connected to a door switch. It turns off any siren tone when the door is opened. The siren tone will continue to be cut off even when the door is closed. Changing any switch on the face of the unit will restore normal function.

HORN RING CYCLER 2 (HRC2)

During installation, the auxiliary input must be connected and the HRC2 option selected. While the siren is in standby, tap the horn ring to bring the unit out of standby into Mechanical tone. Repeatedly tapping the horn ring will cycle through Mechanical, Wail, Yelp, and Phaser tones. Tapping the horn ring twice quickly will stop the siren tones and return the unit to standby. Press- ing and holding the horn ring will produce Horn tone until released. Then the siren will return to its previous siren tone or standby.

See OPTION SWITCHES section for further details.
