Operation

Tone Level - Tone level can be regulated by the front-panel screwdriver-adjustable TONE LEVEL control. Clockwise

rotation increases the level of the tone signal.

Pitch Control - A recessed, screwdriver-adjustable, PITCH control is located on the side-panel and is used to

adjust the frequency of the tone signal.The signal can be varied to suit the individual application requirement.

Figure 2 shows how the Multi-Tone Generator may be used for emergency alarm signalling in an unattended system.

Program input is interrupted by a continuous alarm tone when an external sensing and switching device (i.e., a bi-metal

sensor) momentarily closes the contact at the TRIGGER terminal (“START”).A second external momentary switch con-

nected to the RESET terminal (“STOP”) restores the circuit when the switch is momentarily closed.

EXTERNAL CONTACTS REOPEN.
