The intent of this project was to quantify the effects of installation orientation and appliance geometry on smoke detector response. Both photoelectric and ionization type appliances were tested according to the specifications set by UL 268 using a mineral oil aerosol to simulate smoke. Changes in orientation caused a maximum variation in photoelectric sensors of 34 seconds and in ionization sensors of 15 seconds. Removal of the cover and bug screen reduced the photoelectric response time by approximately 19%, while it increased the ionization response time by approximately 20%.
