Thermoplastic Edge-Lit Exit Sign 101
The Slim Profile Thermoplastic Edge-Lit Exit Sign (QXEDGP) lights a laser-etched acrylic panel from the edge so the word EXIT appears to float. You get a clean, modern look, a tough UL 94 5VA flame-retardant housing, and the flexibility to set arrows and face count on site. It’s the “good-looking, gets-it-done” sign for finished corridors and tenant improvements.
Features & Benefits
- Easy to read: high-output red or green LEDs with large 6" characters for clear wayfinding.
- Even glow: UV-stabilized, ultra-clear acrylic panel spreads light evenly—no hot spots.
- Arrow-ready: peel-and-stick chevrons + template make on-site direction changes painless.
- One box, many installs: ceiling, end, or wall/back mounting with the included canopy.
- Inspector-friendly: UL 924, Damp Location, and Title 20 compliance built-in.
Illumination & Panel Design
Characters are 6" high with a 3/4" stroke and stay uniform edge-to-edge. Single-face units use an ultra-clear panel; double-face units add a mirror-finish insert between two clear panels so both sides pop equally. Need arrows? Apply them in seconds using the included guide so everything lines up cleanly.
Electrical, Battery & Testing
- Power: dual-primary 120/277 VAC, 60 Hz.
- Emergency: maintenance-free 4.8 V Ni-Cd (EM models) with a 90-minute runtime and ~24-hour recharge.
- Seamless transfer: solid-state switchover—no flicker when power drops.
- Quick checks: push-to-test and a bi-color status LED for at-a-glance verification.
- Self-diagnostics (optional): automatic monthly/annual tests with simple fault codes.
Mounting & Installation
The universal canopy snaps in for top (ceiling) or end (flag) mounting, or use the backplate knockouts for wall/back installs over a j-box. Convert between single-face and double-face on site to match sightlines. Hardware’s in the box, so your crew can keep moving.
Installer tip: Set canopy orientation before pulling conductors so the panel squares to the corridor and arrows point the right way the first time.
Use Cases
- Office corridors & TI: a slim profile keeps walls tidy while arrows fine-tune wayfinding.
- Healthcare & education: self-test trims the time you spend on monthly/annual checks.
- Retail & hospitality: the clear panel looks modern at entries and along egress paths.
- Covered lobbies/vestibules: built for humid indoor areas with a Damp Location rating.
