An auxiliary device for a hazard alarm constructed as a point type detector, in particular for a smoke alarm or smoke gas alarm. The device is a separate unit that can be attached to the hazard alarm and is provided to monitor the function thereof. It has a transmitting unit and/or a receiving unit for the detection of objects in the vicinity of the hazard alarm. The auxiliary device monitors smoke inlet openings of the hazard alarm. An arrangement containing the hazard alarm and the auxiliary device attached thereto and matched thereto in terms of construction and/or connections is also provided. The auxiliary device of this kind is used for monitoring the vicinity of the hazard alarm for current-shielding objects, for monitoring an inlet opening of the hazard alarm for contamination and optionally for monitoring the function of an acoustic alarm signaling device of the hazard alarm.
