BS EN 1125:2008 – Panic Exit Devices

It is desirable that doors at final exits in public buildings, places of entertainment, shops etc. should be fitted with panic devices operated by a horizontal push bar or touch bar. The emphasis for products covered by this standard is on safe exit rather than security.

The main purpose of the performance requirements of this standard is to give safe and effective escape through a doorway with minimum effort and without prior knowledge of the device i.e. for locked doors on escape routes where panic situations can be foreseen.

BS EN 1125:2008 applies to type A (push bar panic bolts) and type B (touch bar panic bolts) and classifies panic exit devices by using a 10-digit coding system, each digit referring to a particular feature of the product measured against the standard’s performance requirement.

Digit 1 – Category of use

One category is identified:
Grade 3: high frequency of use by public and others with little incentive to exercise care

Digit 2 – Durability

Two categories are identified:
Grade 6: 100,000 cycles
Grade 7: 200,000 cycles

Digit 3 – Test door mass

Three categories are identified:
Grade 5: up to 100 kg
Grade 6: up to 200 kg
Grade 7: over 200 kg

Digit 4 – Suitability for use on fire/smoke doors

Three grades are identified:
Grade 0: not approved for use on fire/smoke door assemblies
Grade A: suitable for use on smoke door assemblies
Grade B: suitable for use on fire and smoke door assemblies based on a test in accordance with BS EN 1634-1

Digit 5 – Safety

All panic and emergency exit devices have a critical safety function, therefore, only the top grade 1 is identified.

Digit 6 – Corrosion resistance

Two grades of corrosion resistance are identified according to BS EN 1670:2007:
Grade 3: high resistance
Grade 4: very high resistance

Digit 7 – Security

Only one category of security is identified (grade 2). Panic devices are primarily for the operation of a door from the inside. Safety considerations will always be given priority over security.

Digit 8 – Projection of device

Two categories are defined:
Grade 1: projection up to 150 mm (large projection)
Grade 2: projection up to 100 mm (standard projection)

Digit 9 – Type of device

Two types are defined:
Type A: push bar operation
Type B: touch bar operation

Digit 10 – Field of door application

Three categories are defined:
Category A: single door, double door: active or inactive leaf
Category B: single door only
Category C: double door: inactive leaf only

Other issues

A grade 2 (low projection) panic device should be used in situations where there is restricted width for escape or where doors are not able to open beyond 90º. Panic device push and touch bars should be installed to provide the maximum effective length but never less than 60% of the door leaf width.
