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.
Installation 1. Locate the camera’s USB accessory port. 2. Connect the accessory appropriate for one of the following camera types: • IE Series and Spectra HD Series: Connect the accessory directly to the camera’s USB accessory port. NOTE: For Spectra HD Series cameras, the ALM-1 alarm accessory must be connected to the accessory port closest to the dome drive when installed (refer to Figure 1).
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.
ALARM 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. ALM1 ALM2 ALM3 ALM4 RTN 3. Connect UTP wiring from your alarm output devices to the AUD-1 TB2 connector. TB1 1 2 3 4 5 TB2 Figure 3. Wiring the ALM-1 ì Common Return î N.C.
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.
