CQR Alto internal sounder | white | 110 dB | 9–15 V DC | tamper | G3

The CQR Alto is a low-profile, remotely powered internal sounder for intruder alarm systems. It signals an alarm with 110 dB(A) at 1 m; the alternating or continuous tone is chosen by wiring – negative to the common GND terminal and positive to terminal #1 (continuous) or #2 (alternating). The continuous tone does not comply with EN 50131-4. The sound duration is set by the control panel. The tamper switch reacts to the lid being opened and to the sounder being removed from the wall (the separate tamper fixing screw hole must be used). Current draw is low – 107 mA with the continuous and 90 mA with the alternating tone (13.6 V). The sounder is third-party tested and suits EN 50131-1 Grade 3, environmental class II systems.
