└─ Physical degradation

STAGE 2: Functional degradation (performance declining)
├─ Reduced brightness during tests
├─ Shorter duration capability
├─ Intermittent operation
└─ Mounting issues

STAGE 3: Imminent failure (critical)
├─ Units not illuminating
├─ Complete battery exhaustion
├─ Charging circuit failure
└─ Structural failure

STAGE 4: Complete failure (emergency situation)
└─ Non-functional life safety lighting
├─ Regulatory violation
├─ Life safety compromise
└─ Liability exposure
“`

Identifying early warning signs enables proactive correction before Stage 3-4 emergencies.

This article documents four critical indicators that life safety lighting requires immediate professional service, the consequences of delayed response, and 48Fire’s diagnostic and correction protocols.

SIGN #1 → DIM OR INCONSISTENT ILLUMINATION

Visual Brightness Degradation

What you observe:

—

During Normal Operation (AC Power)

SYMPTOM: Exit signs noticeably dimmer than when new

Normal brightness:

• Text/symbols clearly legible from 100 feet
• Uniform illumination across sign face
• Bright, vivid appearance
• No dark spots or shadows

Degraded brightness:

• Text/symbols difficult to read from distance
• Uneven illumination (bright areas and dim areas)
• Washed out, faded appearance
• Dark zones within sign face

What this indicates:

“`
LED DEGRADATION:
├─ LED lifespan approaching end (50,000+ hours typical)
├─ Driver circuit failing
├─ Power supply voltage declining
└─ Replacement needed within 6-12 months

LAMP DEGRADATION (older units):
├─ Incandescent/fluorescent bulb near burnout
├─ Blackening visible on bulb
├─ Filament weakening
└─ Replacement needed within 30-90 days
“`

—

During Battery Backup (Power Failure Simulation)

SYMPTOM: Exit signs much dimmer on battery power than AC power

Normal behavior:

• Similar brightness on battery vs. AC power
• Slight reduction acceptable (10-20%)
• Consistent throughout 30-second monthly test
• No significant dimming during test

Abnormal behavior:

• Dramatic brightness reduction on battery (50%+ dimmer)
• Rapid dimming during 30-second test
• Near-complete darkness by end of test
• Flickering during battery operation

What this indicates:

“`
BATTERY CAPACITY LOSS:
├─ Battery age exceeding lifespan (4+ years for lead-acid)
├─ Capacity degraded to 30-50% of rating
├─ Unable to provide 90-minute duration
└─ IMMEDIATE REPLACEMENT REQUIRED

CHARGING CIRCUIT FAILURE:
├─ Battery not receiving proper charge
├─ Float voltage incorrect
├─ Chronic undercharging
└─ PROFESSIONAL SERVICE NEEDED URGENTLY
“`

48Fire diagnostic protocol:

• Electronic load testing (measures actual capacity)
• Charging circuit voltage verification
• Battery replacement or circuit repair
• Verification testing confirms correction

—

Flickering Lights

SYMPTOM: Life safety lighting flickers or strobes intermittently

Flickering patterns and meanings:

Flicker Type	Likely Cause	Urgency
Constant rapid flicker	Ballast/driver failure (fluorescent/LED)	Immediate (days)
Occasional brief flicker	Loose connection, power fluctuation	Moderate (weeks)
Flicker only on battery	Battery failing, connection issue	Immediate (days)
Flicker after extended operation	Overheating component	Moderate (weeks)
Random intermittent flicker	Faulty wiring, failing component	Immediate (days)

Why flickering is critical:

• Indicates electrical instability
• Component failure imminent
• May fail completely without warning
• Creates visual distraction (occupant confusion)
• Potential fire hazard (overheating components)

Immediate action required:
Life safety lighting flickering = schedule 48Fire service within 24-48 hours to prevent complete failure.

—

SIGN #2 → PHYSICAL DAMAGE OR DETERIORATION

Housing and Mounting Issues

What you observe:

—

Cracked or Broken Housing

VISIBLE DAMAGE:

Minor damage:

• Small cracks in plastic housing
• Lens scratches or cloudiness
• Faded sign face
• Discoloration from age/UV exposure

Severity: Moderate (schedule service within 30 days)

Major damage:

• Large cracks exposing internal components
• Broken lens (missing pieces)
• Housing separated or hanging loose
• Water intrusion visible inside unit

Severity: Critical (schedule 48Fire emergency service within 24 hours)

Why physical damage is urgent:

“`
IMMEDIATE CONCERNS:
├─ Moisture intrusion → Electrical short risk → Fire hazard
├─ Component exposure → Dust/contamination → Premature failure
├─ Broken lens → Reduced visibility → Code violation
└─ Loose housing → Falls on occupants → Injury liability

COMPLIANCE CONCERNS:
├─ NFPA 101 requires exit signs in good physical condition
├─ Damaged units may not pass annual inspection
├─ Fire marshal citation risk
└─ Insurance claim vulnerability if incident occurs
“`

—

Mounting Security Issues

SYMPTOM: Exit signs loose, sagging, or improperly positioned

Mounting problems:

“`
LOOSE MOUNTING:
├─ Sign shifts when touched
├─ Visible gap between sign and wall/ceiling
├─ Screws/bolts visibly loose
└─ Vibration causes movement

CAUSES:
├─ Improper initial installation
├─ Mounting hardware degradation
├─ Vibration over time (HVAC, traffic)
└─ Wall/ceiling material deterioration

URGENCY: HIGH
└─ Unit may fall causing injury
└─ Inspection failure certain
└─ Immediate correction required
“`

Sagging or misaligned signs:

• Sign tilted at angle (not level)
• Pendant-mount signs hanging crooked
• Arrow pointing wrong direction
• Visibility compromised from intended viewing angles

Code violation:
Exit signs must be positioned for visibility from all required approach directions. Misalignment = non-compliance.

48Fire mounting repair:

• Secure remounting with proper hardware
• Alignment verification
• Vibration-dampening if needed
• Inspection-ready positioning

—

Corrosion or Environmental Damage

SYMPTOM: Rust, corrosion, or environmental degradation visible

High-risk locations for environmental damage:

• Humid environments (restrooms, kitchens, mechanical rooms)
• Outdoor or semi-outdoor installations
• Areas with chemical exposure
• Locations near salt air (coastal properties)
• High-temperature locations (near boilers, rooftops)

Corrosion indicators:

“`
EARLY STAGE (Schedule service within 60 days):
├─ Surface rust on metal components
├─ White/green powdery substance on terminals
├─ Slight discoloration of housing
└─ Minor weathering of outdoor units

ADVANCED STAGE (Immediate service within 7 days):
├─ Heavy rust affecting structural integrity
├─ Significant terminal corrosion
├─ Housing warping or cracking from corrosion
└─ Electrical connection compromise visible
“`

Why corrosion is serious:

• Electrical connections degraded (intermittent operation)
• Charging efficiency reduced (battery undercharged)
• Structural failure imminent (housing integrity lost)
• Water intrusion pathway created (short circuit risk)

48Fire environmental damage service:

• Terminal cleaning and protection
• Weatherproof housing installation (if needed)
• Component replacement (corroded parts)
• Environmental assessment (preventing recurrence)

SIGN #3 → TESTING FAILURES

Monthly or Annual Test Performance Issues

What you observe during testing:

—

Monthly Test Failures

NFPA 101 REQUIREMENT: 30-second minimum function test monthly

Normal monthly test result:
“`
Push test button → Sign illuminates immediately
Brightness adequate → Consistent for 30 seconds
Test completes → Sign returns to normal operation
Result: PASS
“`

Abnormal monthly test results requiring immediate service:

FAILURE TYPE 1: No illumination
“`
Push test button → Sign does not illuminate
OR
Sign illuminates very briefly then goes dark

CAUSE:
├─ Dead battery (no charge retained)
├─ Complete charging circuit failure
├─ Lamp/LED failure
└─ Wiring disconnection

ACTION: 48Fire emergency service within 24 hours
COMPLIANCE: System non-functional, immediate violation
“`

FAILURE TYPE 2: Rapid dimming
“`
Push test button → Sign illuminates initially
Sign brightness → Rapidly declines during 30 seconds
End of test → Sign very dim or dark

CAUSE:
├─ Battery capacity critically low (end of life)
├─ Excessive internal resistance
├─ Cell failure within battery
└─ Charging circuit partially failed

ACTION: 48Fire service within 48-72 hours
COMPLIANCE: Will fail 90-minute annual test, replacement urgent
“`

FAILURE TYPE 3: Intermittent operation
“`
Push test button → Sign illuminates
During test → Flickering or cycling on/off
Behavior → Unpredictable and unstable

CAUSE:
├─ Loose connection (vibration-induced)
├─ Failing component (intermittent contact)
├─ Battery terminal corrosion
└─ Driver/ballast failure

ACTION: 48Fire service within 7 days
COMPLIANCE: Unreliable operation unacceptable
“`

Monthly testing documentation:
When monthly tests fail, document clearly and schedule immediate correction. Fire marshal inspections review monthly logs—missing tests or unresolved failures = citations.

—

Annual Test Failures

NFPA 101 REQUIREMENT: 90-minute comprehensive test annually

Normal annual test result:
“`
AC power disconnected → Units activate immediately
90-minute duration → Brightness adequate throughout
Test completion → All units pass full duration
Certification → Professional certificate issued
“`

Annual test failures indicating immediate service need:

FAILURE PATTERN 1: Duration failure
“`
TEST TIMELINE:
0-30 minutes: Normal brightness
30-60 minutes: Brightness declining noticeably
60-75 minutes: Significant dimming
75+ minutes: Units too dim or dark

RESULT: FAIL (did not achieve 90-minute requirement)

CAUSE: Battery capacity below 90-minute rating
ACTION: Battery replacement required before re-test
TIMELINE: 48Fire service within 1 week, re-testing within 2 weeks
“`

FAILURE PATTERN 2: Multiple unit failures
“`
RESULT: 6 of 20 units fail 90-minute test

INDICATION:
├─ Similar-age batteries reaching end of life
├─ Widespread component degradation
├─ Systematic maintenance neglect
└─ Comprehensive service program needed

ACTION: 48Fire complete system assessment
TIMELINE: Immediate (multiple violations)
“`

FAILURE PATTERN 3: Charging circuit issues discovered
“`
TEST REVEALS:
├─ Float voltage outside specification (measured 12.2V, should be 13.6V)
├─ Batteries chronically undercharged
├─ PC board adjustment needed
└─ Possible circuit component replacement required

ACTION: 48Fire charging circuit service
TIMELINE: Immediate (affects all future performance)
“`

Annual test failure consequences:

• System non-compliant (cannot issue certificate)
• Liability exposure during correction period
• Insurance coverage questionable
• Occupancy restrictions possible (severe cases)
• OSHA citation risk if inspection occurs

48Fire annual testing and correction:

• Comprehensive 90-minute testing all units
• Electronic load testing reveals capacity issues
• Same-visit corrections (when possible)
• Return visit scheduled (if parts needed)
• Re-testing and certification upon completion

SIGN #4 → AGE AND LIFECYCLE INDICATORS

Equipment Lifespan Milestones

What equipment age reveals about service needs:

—

Battery Age Critical Thresholds

LEAD-ACID BATTERIES (Most common):

“`
AGE 0-2 YEARS: Peak performance
├─ Service need: Routine testing only
├─ Urgency: None
└─ Action: Continue monitoring

AGE 3 YEARS: Early degradation begins
├─ Service need: Enhanced monitoring recommended
├─ Urgency: Low
└─ Action: Begin planning for Year 4 replacement

AGE 4 YEARS: Accelerated decline period
├─ Service need: PROACTIVE REPLACEMENT RECOMMENDED
├─ Urgency: MODERATE
└─ Action: Schedule 48Fire battery replacement within 6 months

AGE 5+ YEARS: Failure zone
├─ Service need: IMMEDIATE REPLACEMENT REQUIRED
├─ Urgency: CRITICAL
└─ Action: 48Fire emergency battery service within 30 days
“`

How to determine battery age:

• Check service tag (last replacement date)
• Review annual test certificates (battery dates noted)
• Inspect battery for date code (if visible)
• Contact 48Fire for records review (if service history unknown)

Why age matters:
Even if batteries pass monthly 30-second tests at Year 5, they likely lack capacity for 90-minute annual test. Proactive Year 4 replacement prevents annual test failures.
