Fire, gas & emergency
Emergency exit signs: LED and backup power
LED exit signs with reliable backup power are standard for many commercial fit-outs. Legibility and battery duration dominate selection.
Legend and viewing
Correct pictogram/arrows and viewing distance matter more than decorative housings.
Maintain luminance over battery mode.
Backup
State duration and recharge behaviour.
Test switches should be accessible.
Logistics
Protect faces; ship arrows/pictograms as ordered—mix-ups are common.
NMF verifies legend variants on packing lists.
