Specifications

4 C2985M-A (3/11)
Description
The AUD-1 and ALM-1 are external accessories that can be connected directly to the accessory port of
compatible Pelco devices. The AUD-1 is compatible with Spectra
®
HD Series dome systems and all Sarix
®
camera models that do not have built-in audio. The ALM-1 is compatible with Spectra HD Series dome
systems and all Sarix camera models.
The AUD-1 audio accessory is designed to work with microphones that have an internal preamplifier and
provide a line-level output. The AUD-1 encodes audio from the microphone into a digital G.711 format. The
audio can be streamed with the video to be played back and recorded at the headend. The AUD-1 can also
receive the G.711 digital audio from the headend and convert it to an analog signal to be played through a
speaker.
The ALM-1 alarm accessory features four alarm inputs, one auxiliary (Form C) relay output, and one open
collector auxiliary output that can be alternatively configured to operate on alarm. Up to four ALM-1 alarm
accessories can be configured for one device, which may require a USB hub. Each accessory is
automatically recognized and configured by the Pelco device.
The audio and alarm accessories can be used simultaneously; however, if the Pelco device has only one
accessory port, a USB hub is required.
NOTE: The ALM-1 accessory is not supported by DS ControlPoint.
