Abstract

A chemical agent detector having a pair of vapor/aerosol chemical agent dctor cells mounted with a lithium battery in a detection cell module. A liquid agent detector having a hinged plate is attached to an electronic system which includes a signal processor that energizes a plurality of warning LED'"'"'s and a horn in response to energization of selected agent detectors. An air pump is mounted on the housing for the electronics to force air across the detection cells. The detection cell module is connected to the housing for the electronics. A battery compartment is connected to the detection cell module and includes means for permitting an external power source to be connected thereto.

Claims

1. A chemical agent detector comprising:

a housing;

a liquid agent detector unit pivotally connected to said housing;

wherein said detector unit includes a flat plate and a hinged bracket joined to said flat plate and said housing for holding said plate in a position extending from said housing; and

an aerosol/vapor chemical agent detector module removably joined to the housing; and

a battery compartment removably joined to said detector module.

2. The detector of claim 1 wherein said detector module includes at least one aerosol/vapor detector cell having a diffusion screen mounted thereon.

3. The detector of claim 2 further including a forced air means mounted on said housing for forcing air across said screen.

4. The detector of claim 3 further including a battery mounted in said battery compartment for providing electrical power to said cell.

5. The detector of claim 4 wherein said module includes a plurality of aerosol/vapor detector cells.

6. The detector of claim 5 further including output terminal means for connection to a remote warning device.

7. The detector of claim 6 further including audio warning means mounted on said housing for sounding an audio alarm when an agent is detected.

8. The detector in accordance with claim 7 further including lights mounted on said housing for providing a visual warning when an agent has been detected.

9. The detector in accordance with claim 8 wherein a plurality of lighting means are provided on said housing for providing a warning for the detection of different agents.
