The ASK-4 501-TLM-E Audio Monitoring Kit from Louroe Electronics is a single-zone audio monitoring system with 2-way talk / listen capabilities. This kit consists of a TLM-E 2-Way Speaker / Microphone, an AP-1 TB Audio Base Station, an AD-1 Plug-In Switching AC Adapter, and a Dual RCA Connector Cable.

The AP-1TB Audio Monitoring Base Station is a single-zone non-alarming unit with listen and talkback features. As a system (with a Louroe speaker / microphone), it provides live audio with its built-in 4" (10.16cm) speaker and features a built-in microphone for talkback. The distance between AP-1TB base station and speaker / microphone can be up to 1,000' (305m).

The TLM-E Speaker / Microphone is a 2-way speaker / microphone unit that contains an electret condenser microphone and a 4” (10.16cm) speaker. It comes with a metal backbox for surface mounting to a wall or flat surface and a plastic backbox for flush mounting.

The UL listed AC Adapter supplies 12VDC, 500mA to the AP-1TB Base Station and the TLM-E Speaker / Microphone. A Dual RCA Connector Cable is provided for making an input / output connection to a DVR / VCR for audio recording and playback.

Note: Wiring Requirements: 4-conductor cable consisting of 2 conductors shielded, 20 gauge with 22 gauge drain (microphone connection) and 2 conductors unshielded, 18 gauge (speaker connection), all in the same jacket.
When this equipment is used as part of an audio monitoring system, the law requires that the public be given notice of AUDIO MONITORING ON THE PREMISES. A decal notice is included with each microphone shipped.
