Recessed detector assembly for detecting and venting airborne substances
First Claim
1. A recessed detector assembly, comprising:
- a detector frame adapted to be flush mounted into a mounting box mounted in a ceiling or a wall, the frame having exposed vents for allowing air containing airborne substances to enter the frame;
at least one sensor mounted in the detector frame for sensing one or more of the airborne substances;
means for exhausting the airborne substances,the at least one sensor generating a signal causing the means for exhausting the one or more airborne substances to operate when a presence of the one or more of the airborne substances is sensed to exceed predetermined levels,wherein the means for exhausting the airborne substances is a drop down sensor, the drop down sensor being provided with additional exposed vents.

Abstract
A recessed detector assembly having the capability to detect and evacuate air laden with airborne substances from within the assembly. The assembly includes a detector frame adapted to be flush mounted into a mounting box mounted in a ceiling or a wall, the frame having exposed vents allowing air containing airborne substances to enter the frame; at least one sensor mounted in the detector frame for sensing one or more of the airborne substances and for exhausting the airborne substances, the at least one sensor generating a signal causing an exhaust fan or a drop down sensor for evacuating the one or more airborne substances to operate when a presence of the one or more of the airborne substances is sensed to exceed predetermined levels. Accordingly, the detector may be promptly reset and an alarm may be promptly turned off when airborne substances in the room drop below the predetermined levels.

15. A method for detecting airborne substances in a recessed detector assembly, comprising the steps of:
-
determining when airborne substances in a detector assembly reach a predetermined level; generating a signal to activate a drop down sensor with exposed vents, the drop down sensor with exposed vents serving as an exhaust mechanism; evacuating the airborne substances from the assembly; and stopping the signal activating the exhaust mechanism when the airborne substances have been reduced below the predetermined level. - View Dependent Claims (16, 17, 18)
