Low Profile Thermoplastic LED Exit Emergency Combo - CEM, Red/Green Letters, UL 924
The CEM Low-Profile LED Exit & Emergency Combo combines a code-legible EXIT sign with two adjustable LED emergency heads in a compact thermoplastic housing. Use it for standard indoor commercial egress paths where a shallow, economical exit sign with emergency lights is preferred over separate fixtures. The series supports red or green letters, white or black housing, optional remote-capable exit emergency combo output, optional self diagnostics, and optional USA assembly.
Choose CEMRW or CEMRB for red EXIT letters, and choose CEMGW or CEMGB for green EXIT letters. Add RC when the fixture needs a small 1.0 W remote-head output, SDT when the maintenance plan calls for self diagnostics, or the USA-assembled configuration when purchasing documents require it.
Best For
This low-profile thermoplastic exit emergency combo is a strong fit for low-ceiling corridors, tenant buildouts, offices, classrooms, small retail suites, hospitality back-of-house areas, storage rooms, and standard indoor commercial egress routes where inspectors expect UL 924 signage and 90-minute emergency lighting from one fixture.
Key Features
- UL 924 listed emergency combo; damp-location rated from 0-40 �C / 32-104 �F.
- Compact, low-profile cabinet molded from UL 94 5VA flame-retardant thermoplastic for durable, non-conductive protection.
- Two adjustable 0.5 W LED lamp heads for corridor, landing, doorway, and small-room emergency illumination.

Illumination
- Two adjustable 0.5 W LED heads help cover typical doorways, corridors, vestibules, landings, and small rooms.
- Even red or green LED legend illumination supports clear wayfinding during normal and emergency operation.
- For best coverage, aim each head down the path of egress and overlap beams at turns, doorways, or floor transitions.
Electrical
- Universal 120/277 V input for common commercial branch circuits.
- Bi-color indicator shows normal/service status, with push-to-test for functional checks.
- After a full charge, the onboard 3.6 V Ni-Cd pack powers the EXIT legend and emergency heads for the required 90-minute runtime.
- Solid-state transfer and two-rate charger support reliable emergency switching and approximately 24-hour recharge.
- Allow a full charge cycle before running the annual 90-minute discharge test.
Mounting & Face Setup
- Wall mount: universal knockout backplate supports surface mounting on common junction-box patterns.
- Ceiling or end mount: EZ-snap canopy supports top or side installation where the sign must be viewed from the egress path.
- Field-convertible face design supports single-face and double-face applications; use double-face setup where people approach from both directions.
- Align directional chevrons and final face count with the approved path of travel.
Housing / Thermoplastic Body
- Flame-retardant UL 94 5VA thermoplastic housing keeps the fixture lightweight and non-conductive.
- Low-profile silhouette minimizes projection into corridors and suits standard commercial interiors.

CEM vs Alternatives
Choose the CEM when you need an economical low-profile thermoplastic LED exit emergency combo for standard indoor egress. Step up to a thin thermoplastic combo when you want a sleeker body or higher remote capacity, and move to steel or Chicago-approved units when the project requires a tougher cabinet, higher-output heads, or jurisdiction-specific construction.
| Model | Best Match | Key Difference |
|---|---|---|
| This CEM model | Standard indoor corridors, offices, classrooms, retail, and tenant spaces | Low-profile thermoplastic body, dual 0.5 W heads, optional RC/SDT/USA assembly |
| Compact thermoplastic combo | Projects needing more configuration depth or remote capacity | More option combinations, including broader output and no-head configurations |
| Die-cast aluminum combo | Architectural interiors and finish-sensitive spaces | Metal housing and more refined appearance |
| Chicago-approved steel combo | Chicago and steel-housing specifications | 8" red legend, steel cabinet, higher-output heads, and jurisdiction-specific design |
Frequently Asked Questions
Is this a UL 924 low-profile exit sign with emergency lights?
Yes. The CEM is a UL 924 listed low-profile thermoplastic LED exit sign and emergency light combo with integrated EXIT legend, two adjustable emergency heads, and 90-minute battery backup.
Can this exit/emergency combo be ceiling mounted?
Yes. The included canopy supports top or end mounting, so the unit can be ceiling mounted or side mounted where the egress path requires that orientation. It can also be surface wall mounted with the universal backplate.
Is this model remote capable?
Remote capability is optional. Select an RC configuration when you need 1.0 W of remote output for a nearby remote head. Standard configurations do not include remote capacity.
Does this product support self diagnostics?
Yes. Choose an SDT configuration if the project requires self-testing or self-diagnostic functionality for automated maintenance checks.
Should I choose red or green exit letters?
Match the project documents, local requirements, and existing exit signage. Red is common in many facilities, while green is often selected where the building already standardizes on green wayfinding.
What are common CEM SKUs for this combo?
Common base configurations include CEMRW, CEMRB, CEMGW, and CEMGB. Additional SKU suffixes identify remote-capable, self-diagnostic, and USA-assembled versions.
What is the difference between this CEM combo and a thin thermoplastic combo?
The CEM is the economical low-profile thermoplastic choice for standard indoor egress. A thin thermoplastic combo is usually selected when the project needs a slimmer architectural look, higher output, or a broader option set.
