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
camera models that do not have built-in audio. The ALM-1 is compatible with Spectra HD Series dome
systems and most 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.

Wiring

AUDIO

NOTES:

• The maximum recommended cable length for the audio wiring is 304.8 m (1,000 ft).

• The AUD-1 is designed to work with microphones that have an internal preamplifier and provide
professional line-level output (+4 dBu).

• If your microphone requires more than 12 VDC power, you will need to use a separate power line to
power the microphone unit.

• If your microphone is a consumer line-level device (–10 dBu), the audio output may be quieter than
you expect. Mic-level devices are not recommended as they must be amplified to a line-level signal,
which often results in excessive noise.

To connect the wiring for the AUD-1:

1. Connect UTP wiring from an external microphone to pins 2 and 3 of the AUD-1 TB2 connector.

2. To supply power to the microphone, connect UTP wiring to the power terminals of the microphone
and terminate them at pins 1 (12 VDC) and 4 (return) of the AUD-1 TB2 connector.

3. Connect UTP wiring from the external speakers to pins 1 and 2 of the AUD-1 TB1 connector.

1. Connect one wire of a UTP wire pair from each of your alarm input switches to pins 1 to 4 of the
ALM-1 TB1 connector.

2. Connect the remaining wire of the UTP wire pair from your each of your alarm input switches to a
wire nut or terminal block, and then run a single wire to the return pin 5 of the ALM-1 TB1 connector.

3. Connect UTP wiring from your alarm output devices to the ALM-1 TB2 connector.

CONNECTING A RELAY DEVICE

The ALM-1 has four outputs for activating external devices. It supports both momentary and continuous
relay operation.

You can operate the relays interactively during an active connection, or they can operate automatically to
coincide with certain events. Typical applications include turning on lights or other electrical devices or
activating a door, gate, or lock.

WARNING: Do not exceed the maximum relay ratings of 40 V, 2 A, or 60 W.

CONNECTING ALARMS

The ALM-1 provides four alarm inputs for external signaling devices, such as door contacts or motion
detectors. Both normally open and normally closed devices are supported.

Supervised Alarms

When an alarm is configured as a supervised alarm, the ALM-1 maintains a constant electrical current
through the alarm circuit (3.3 VDC, 1 kohm). If the alarm circuit length changes, due to an electrical short
or a bypass, the voltage fluctuates from its normal state and activates an alarm.

NOTE: Install the 1-kohm resistor as close to the switch as possible.

Figure 4 illustrates the alarm and no alarm conditions of a supervised alarm input. Whether the alarm is
normally closed or normally open, neither a cut nor a bypass can defeat these alarms.

When an alarm is configured as an unsupervised alarm, an alarm is only activated when the normal alarm
state (open or closed) changes.
