The ASK-4 #504-TLM-W Audio Monitoring Kit from Louroe Electronics is a 4-zone audio monitoring system with 2-way talk / listen capability. It consists of 4 TLM-W 2-Way Speaker / Microphones, and an AP-4TB Audio Base Station.

The AP-4TB Audio Monitoring Base Station is a 4-zone unit designed to achieve 2-way listen / talkback functionality. As a complete system, any zone can be monitored, by pressing the button switch for the desired zone. The unit contains a 3” (7.62cm) built-in speaker for monitoring audio and a built-in microphone for talking back to the remote zone. Each zone has an audio output jack (RCA) for making a connection to a DVR with multiple audio inputs. It is suitable for use in jail cell monitoring, building peripherals, therapy labs, warehouse, classroom monitoring, storage facilities, day care centers, or anyplace where CCTV cameras are installed.

The TLM-W Speaker / Microphone is a 2-way unit that has an electret condenser microphone and a 2.5” (6.35cm) speaker, all within a single housing. As part of a Louroe audio system, it provides 2-way communication between the remote area and the audio receiving device (Louroe Base Station, etc). A plastic back box is provided with each speaker / microphone unit for surface mounting to a wall.

Note: Wiring Requirements: 4-conductor cable consisting of 2 conductor shielded, 20 gauge with a 22 gauge drain (for microphone connection) and 2 conductors unshielded, 18 gauge (for speaker connection).
