Product Highlights
  • Made in USA

The ASK-4 #501-TLMC-W Audio Monitoring Kit from Louroe Electronics is a single-zone audio monitoring system with bi-directional audio capabilities. This kit consists of an AP-1 TB Audio Base Station, a TLMC-W Remote Call Station, a 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 functionality. As a system (with a Louroe speaker / microphone), it provides live audio with a built-in 4" (10.16cm) speaker and features a built-in microphone for talkback to the remote area. The distance between AP-1TB base station and speaker / microphone can be up to 1,000' (305m).

The TLMC-W Speaker / Microphone is a 2-way talk / listen remote call station. It features a microphone, a speaker, and an call button within a single housing. As part of a Louroe Audio Alarming System, it can activate the Louroe Base Station (ALA or DG series) by a sound exceeding the threshold level or by pushing the call button. Once powered a selector switch on PC board allows a choice of activation by pushbutton only, or a combination of pushbutton and sound activation. An LED light illuminates when a call is acknowledged from the Louroe Base Station. It is suitable for use in parking structures, gate entrances, warehouses, stairwells, hallways, elevator cabs, and lobbies.

The UL listed AC Adapter supplies 12VDC and 500mA to the AP-1TB Base Station and the TLMC-W 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: Wire Type: West Penn 356 or equivalent
4-conductor cable consisting of 2 conductors shielded, 20 gauge with 22 gauge drain (for microphone connection) and 2 conductors unshielded, 18 gauge (for speaker connection), all in the same jacket.
