Page 27: Operation
An internally generated siren is also available in WAIL or YELP modes. When the AA21-400 is turned on, a 28 Vdc switched signal is generated. This signal is used to turn on the PA amp relay (if connected in system). The high current DC power to operate the PA110/220 or PA250/700 is supplied by the aircraft. -
Page 28: Input Function Selection
Volume Control Volume Control The volume control knob (VOL) on the front of the AA21-400 is used to adjust the level of the selected output. Rotating the knob clockwise will increase the volume, and counter-clockwise will decrease it. For external paging and rebroadcast operations, the volume should always be set between half and full level. -
Page 29: Mode Switches
Siren Mode The siren mode switch is a three position, centre-off locking switch on the front of the AA21-400. The siren is operated by selecting the mode (YELP or WAIL) and then activating a remote Siren key. The siren will sound only as long as the mode is selected to WAIL or YELP and the Siren key is activated.
