This has a 70mm x 40mm loudspeaker and a flush mounted electret microphone. All components are mounted on a single machined aluminium plate designed to fit a standard UK domestic flush back-box of the type typically used for cooker-switch units (27-379 Tecpro LS379FB flush-mounting back box for LS371). Suitable M5 screws are supplied for attaching the aluminium front plate. Spares are available (14-355).

Cable entry is through the standard knock-out on the back-box rear or side face and termination is via an internal junction-block. The LS371 derives its power directly from the 24V DC Tecpro line. A green LED indicates power is present. Installers should note that the back-box must be turned through 90 degrees from its more usual orientation. A template is provided to aid fitting. Dimensions: 180 x 170 x 57 (l x w x h) mm. Weight: 950g.
