Abstract: A combined flashlight, smoke detector and emergency alarm assembly. A housing contains a flashlight having a bulb, reflector and window at one housing surface for illuminating an area adjacent to the assembly. A smoke detector is enclosed by said housing and includes an alarm for indicating the presence of smoke. A relay automatically turns the flashlight on when the alarm is activated. Vents in the housing permit ingress of smoke to the detector. A battery assembly in the housing provides power for the flashlight, smoke detector and alarm. A manually operable, momentary, normally closed, switch is provide to permit the alarm to be disabled, with the alarm enabled if this switch is released. Another switch is provided to enable the alarm independent of the smoke detector system as an emergency alarm. A manual flashlight switch is further provided to permit the flashlight to be used in a normal manner in a non-alarm situation. The battery assembly includes plural battery cells providing a higher voltage to the smoke alarm and having a tap to provide a relatively lower voltage to the flashlight.

Abstract translation: 手电筒，烟雾探测器和紧急报警器组合。 壳体包含在一个壳体表面处具有灯泡，反射器和窗口的手电筒，用于照亮与组件相邻的区域。 烟雾探测器由所述壳体包围，并且包括用于指示存在烟雾的报警器。 当报警激活时，继电器自动将手电筒打开。 住房通风口允许烟雾进入检测器。 外壳中的电池组件为手电筒，烟雾探测器和报警器提供电源。 提供手动可操作的瞬时常闭开关，以允许警报被禁用，如果该开关被释放，则启用警报。 提供另一个开关，以使报警独立于烟雾探测器系统作为紧急报警。 还提供手动手电筒开关，以允许在非报警情况下以正常方式使用手电筒。 电池组件包括向烟雾报警器提供更高电压的多个电池单元，并且具有用于向手电筒提供相对较低电压的抽头。
