BS EN 179 – Practical Guide to Emergency Exit Devices (Trained-Only)

BS EN 179 applies to doors used by staff or trained persons who know the exit and how it operates. Hardware uses a push pad or lever handle and is typically installed on single internal doors. This guide explains where EN 179 applies, the device types (bolt / latch), how to install and document them, and when to specify EN 1125 instead. 

1) Scope – when EN 179 is appropriate

• Trained-only / staff-only routes (offices, back-of-house corridors, stores, plant/technical rooms).
  
  

• Operation via push pad or lever; users are familiar with the exit.
  
  

• Not for public access: if members of the public may need to exit, specify EN 1125 (touch bar).

2) Device types under EN 179 (and typical use)

Bolt (Push Pad Emergency Exit Bolt)

• A push pad retracts a single-point bolt/latch.
  
  

• Suits internal single doors in staff-only areas where a compact action is preferred.

Latch (Lever / Push Pad Latch)

• A lever or push pad operates a latch for quick release.
  
  

• Ideal where lever familiarity or furniture consistency is desired.
  Learn more → /products/emergency-exit-devices-en-179/latch/
  
  

Note: EN 179 devices are usually single-leaf. For double doors or public routes, check EN 1125 vertical-rod or rim on a centre mullion.

3) Installation & height notes (get it right)

• Use the manufacturer’s template; set pad/lever height within the recommended range.
  
  

• Verify latch throw and keeper/strike capture before final tightening.
  
  

• Confirm closer interaction (the door must relatch smoothly without drag).
  
  

• For outside re-entry, ensure the trim/cylinder engages correctly with the device cam/spindle.

4) Single vs double doors

• Single internal doors (typical): EN 179 bolt or latch is appropriate for trained-only routes.
  
  

• Double doors: EN 179 is not typically used for main egress on pairs. Where pairs are present on a trained-only route, consult your authority; many projects require EN 1125 vertical-rod pairs or paired rim with a centre mullion.
  See EN 1125 pairs → /products/panic-exit-devices-en-1125/double-door-kits/

5) Fire-door compatibility – approvals must match

For fire doors, approvals must align across:

1. Device model (EN 179),
   
   

2. Strikes/keepers matched to frame material,
   
   

3. Fixings (specified screws/through-fix).
   
   

Keep datasheets and record components against the door leaf certificate.
Accessories hub → /products/accessories/

6) Signage, re-entry & trims

• Provide clear emergency exit signage; keep the device unobstructed.
  
  

• For controlled re-entry from the safe side, specify outside trims with cylinder kits (key–key or key–thumbturn).
  
  

• Match cylinder length/profile to the door build-up and trim; avoid over-projection.
  Trims & cylinders → /products/accessories/outside-trim-handles/ · /products/accessories/cylinder-kits/

7) Inspection & record-keeping (UK-focused, globally applicable)

Adopt a simple log that supports audits:

• Frequency: monthly + after works/events.
  
  

• Checks: operating force, relatching, fixings, keeper/strike seating, closer action, signage, damage/vandalism.
  
  

• Records: door ID, device family (EN 179 bolt/latch), accessories used, corrective actions, date/initials.

8) Common mistakes (and how to avoid them)

1. Using EN 179 on public routes → If public may exit, specify EN 1125.
   
   

2. Incorrect height → Follow the template range for lever/pad.
   
   

3. Poor keeper seating → Dry-fit, check engagement line, shim/pack as required.
   
   

4. Wrong strike for the frame → Match to timber/steel profile and reveals.
   
   

5. Assuming double-door suitability → For main egress pairs, use EN 1125 solutions.
   
   

6. Mismatched trims/cylinders → Use device-family–compatible trims; confirm cylinder length/profile.
   
   

7. Obstructions (stock, bins) → Keep approach and device clear.
   
   

8. No inspection trail → Maintain a log with dates, actions and signatures.

9) Quick selector – choose your starting point

• Staff-only single door (compact action): EN 179 bolt → /products/emergency-exit-devices-en-179/bolt/
  
  

• Staff-only single door (lever action): EN 179 latch → /products/emergency-exit-devices-en-179/latch/
  
  

• Any route with public access: Switch to EN 1125 → /products/panic-exit-devices-en-1125/

FAQ – BS EN 179

Q1: EN 179 vs EN 1125—how do I decide?
If users are trained and the route is staff-only, EN 179 may apply. If the public may need to exit, use EN 1125.

Q2: Can EN 179 be used on double doors?
Not typically for main egress. Many authorities require EN 1125 on pairs. Confirm with your AHJ.

Q3: Are EN 179 devices fire-door compatible?
Many are, but approvals must match the door certificate—device, strikes/keepers and fixings.

Q4: Push pad or lever—what should I choose?
Both comply. Push pads are compact and intuitive; levers suit furniture consistency. Consider user training and door use.

Q5: Can I add re-entry from the outside?
Yes—use outside trims with cylinder kits (key–key or key–thumbturn), matched to your device family and door thickness.

Q6: Why does the door fail to relatch?
Usually keeper misalignment or over-tightened fixings. Re-check engagement, adjust the closer and tighten progressively.
