UL Listed Stainless Steel 304 Fire Rated Panic Exit Device -DDPD003

1. Code & occupancy requirements
• International Building Code (IBC) and NFPA 101 require panic hardware on most doors serving Assembly (A), Educational (E), High-Hazard (H) and certain Institutional occupancies once the calculated occupant load reaches 50 or more people

  .
• Local fire marshals or building departments may lower that threshold or extend the rule to other occupancy types; always verify the exact ordinance for your jurisdiction.
2. Door location and function
• Any door that is designated as a “means of egress” leading to the exterior, a stairwell, or a horizontal exit is normally a candidate.
• If the door is a fire-rated barrier (e.g., stairwell or shaft enclosure) you must use a fire-rated panic device that bears the proper UL or BS EN label and keeps the door latched during a fire; non-rated devices are acceptable on ordinary exit doors

  .
3. Accessibility & usability
• ADA, ICC A117.1 and most regional accessibility standards limit the unlatching force to 15 lb (≈67 N) and require the operable portion to be mounted 34-48 in (860-1220 mm) above the floor so children, wheelchair users, and people with limited dexterity can activate it with a simple push

  .
4. Security vs. life-safety balance
• Panic bars allow free egress from the inside while the outside can remain locked, deterring unauthorized entry.
• You can add alarms, delayed-egress hardware, or electrified latch-retraction that ties into access-control, but each option must still release within 15 s (or the code-specified time) when power fails or the bar is pushed

  .
5. Traffic volume & abuse level
• High-frequency or industrial openings call for heavy-duty “crash” or “cross-bar” models made of stainless steel; lighter-duty push-pad styles suffice for small offices or retail back doors

  .

1. Door construction & aesthetics
• Rim-style devices are easiest to retrofit on wood or hollow-metal doors; mortise or vertical-rod models give a cleaner look and higher security but require pocket prep or floor strikes.
• Narrow stile aluminum or all-glass doors need manufacturer-specific kits.
2. Environmental & electrical considerations
• Exterior doors exposed to weather must carry a weather-resistance rating.
• If you need electric dogging, remote release, or integration with fire-alarm relays, select an electrified panic bar that lists compatibility with your power-supply and control system

  .
3. Cost & maintenance
• Fire-listed and electrified units cost more and must be inspected at intervals mandated by NFPA 80/101 (usually annually). Factor in parts availability and who will service the hardware over its life cycle.
