According to one embodiment, an access door for a hazard detector includes a release member that releasably secures the access door in a closed position over a battery compartment of the hazard detector. The release member allows the access door to be pivoted open and closed relative to the battery compartment and hazard detector. The access door also includes a first hinge member and a second hinge member. The first hinge member enables the access door to pivot along a first pivot path and by a first pivot amount and the second hinge member enables the access door to pivot along a second pivot path and by a second pivot amount. A cumulative total of the first pivot amount and the second pivot amount is substantially greater than either pivot amount alone.
