2.12 Alarm Mode

The LH-3000 can operate as a burglar alarm by connecting an external, normal-open switch to the ALRM terminals on the rear panel.

Both horn speakers are selected automatically when the alarm mode is enabled. If the alarm is triggered, the volume output is automatically set to maximum.

Enabling the alarm mode

1.Press and hold down the [Upper Signal Select] key until the YELP indicator flashes. Note that you may light the MAN indicator (with the [Lower Signal Select] key) instead of the YELP indicator.

2.Press the [FUNC] key until the ALL, FWD, AFT and BOTH indicators light. The YELP indicator goes off.

3.After approximately five minutes, the ALL, FWD, AFT and BOTH indicators go off. Then the equipment goes into standby, lighting the BOTH indicator every four seconds to indicate standby mode.

See the next page for procedure flow.

When an attempt is made to remove the Loud Hailer, the alarm sound is released through both horn speakers at maximum volume. The alarm sounds for two minutes followed by a five-minute rest time. The BOTH indicator lights every four seconds during the sounding of the alarm or the five-minute rest period.
