Overview
What it is and how it fits the system.
This is the wall sounder VID variant with a built in isolator: a loop powered, wall mounted sounder whose RED lens carries a visual indicating device alongside the audible output.
The visual side has a firm limit. This product is not approved to EN54-23 (Visual Alarm Device) and must not be used as a visual alarm device to provide a primary warning notification of fire. As a sounder it is EN54-3, and LPCB approval applies.
Tone choice runs to 32 built-in tones, addressing is by rotary decade address switches, and anti-tamper provision is included. The body runs to 121mm diameter and 64mm height at 238g, rated -25°C to +70°C at 95% relative humidity maximum, non-condensing, with low power requirements and an optional IP65 rating.
