Description

The AVI Mk2 is an illuminated warning sign that produces distinct audible and visual indication of an emergency. It is designed for use with fire alarm or gaseous fire extinguishing systems, or other applications where clear audio-visual warning is required. On activation, the AVI’s internal LEDs illuminate the lettering on the 2 or 3 line sign faceplate/s and the internal loudspeaker produces either ISO 8201 or AS 2220 audible warning signals.

The internal speaker has a link selectable Quiet option that reduces the tone volume by 10dB. The IP65 model comprises an indoor AVI mounted inside a UV-resistant IP65 enclosure with a transparent lid.

A range of high visibility UV-resistant faceplates is available.

Configuration Options
Illumination of the top and bottom sign sections and selection of the tones to be used is field programmable using internal links. This way, the AVI can readily display either two-stage or alternate warnings. Up to four lines of text may be accommodated on the faceplate, although use of two or three lines is standard. For situations with low ambient light, the sign illumination can be reduced by removing a resistor in each LED Board driver. This also reduces current consumption. Expansion options include an LED board kit to convert a red 2-line unit to 3-line and a back-box kit to expand a red 2-line unit to ceiling mounted, double sided format. Several AVIs may be synchronised by connecting the ‘Sync’ terminals (an additional wire is required between units).
