Does the Shooter Suppression System meet building codes?

Yes, There are no International Building Codes or International Fire Codes that preclude installation of the Shooter Suppression System, as per determination by the International Code Council Evaluation Services and the Minnesota State Fire Marshals.

What if an active threat occurs in a room full of people?

Deployment of the zone of threat will impact all people in the zone, but will not impede the ability of anyone outside of the spray to either run, hide, or fight (as the Federal Emergency Management recommends). In-House Responders can move through the exposed area as soon as the spray stops, and intercede in the event the perpetrator is not able to focus on continuing with violent activity.

Who has the authority to deploy the system?

Each building owner determines who will be authorized to deploy the system upon recognition of a threat in the building.

Can the system be installed in buildings with unique ceilings?

The shooter suppression system can be installed in a variety of ways to accommodate unique ceiling types using recessed mounting, below ceiling mounts, exposed mechanical ceiling mounts and pendant style mounts. Unique ceiling placement may require custom engineering.

Can the system be installed outdoors?

The shooter suppression system can be installed outdoors in mild climates.

What does the Repuls solution do?

The Repuls solution causes significant irritation to the eyes, nose, throat, lungs, and skin. Exposure results in involuntary eye closure, coughing, and breathing discomfort. Repuls has a pungent odor and stings the skin.

How long do the effects of the Repuls solution last if it’s not treated right away?

The effects of the solution will last as long as the material is in contact with the skin, nose, throat, and eyes, or until the solution evaporates or dries.

Are there long-term effects of being exposed to the Repuls solution?

There are no long-term effects from exposure to Repuls when used as directed and mitigated by flushing face with water. Force flushing of the eyes is not recommended.

Is the solution harmful to children?

The Repuls solution will cause significant discomfort for any age person. Testing by a nationally recognized laboratory has shown the solution will not cause long lasting irritation when used in the manner designed and mitigated by the in-house responders with water.

How long will the Repuls solution incapacitate someone?

Effects will vary by person but mostly the Repuls solution will continue to affect the eyes, nose and breathing until rinsed with water.

Is the solution poisonous/hazardous?

The Repuls solution is a non-poisonous, non-hazardous, water-based mixture and is only slightly acidic with a pH of 5.6-5.8, less than Coke or Pepsi. Care should be taken to ensure that a large amount of Repuls is not ingested.

Is the solution difficult to clean up after a deployment?

The Repuls solution cleans up easily by dilution with water and mild soap.

How does the solution affect those with asthma/other health concerns?

Test subjects with asthma reported easing of the effects upon moving to fresh air.

How quickly will the Repuls solution incapacitate someone?

Effects will vary by person and by deployment accuracy but generally an individual will be incapacitated within 10 to 25 seconds.

Does the Repuls deploy in a fog or aerosol?

No, the Repuls solution is distributed in liquid form similarly to fire sprinklers.

How is Repuls disposed of?

Repuls is safe for disposal in existing sewer lines by diluting with water.

Is the solution flammable/combustible?

The Repuls solution is nonflammable and noncombustible.

Is Repuls lethal?

No, Repuls was designed to irritate any affected individual and be easily mitigated/treated with water.

How long before a person can safely enter a zone after a deployment?

It is safe to enter the zone immediately after deployment. Some irritation may be endured. Surfaces may become slippery when wet so enter with stable footing.

Does Repuls cause mold or mildew?"

The Repuls solution does not cause mold or mildew.

Is this an Access Control Technology?

No, the threat suppression system is an independent technology developed to be an Active Threat Suppression System. It does not block egress or forceful entry but rather it is a tool to be used to suppress the threat when the threat is entering or inside the facility.

Will the threat suppression system deploy automatically after a gunshot?

No, the threat suppression system relies upon visual recognition of the threat for deployment.

Who will be notified if there is an alert?

Only users with the system touchscreen will be sent the Alert. The threat suppression system is not designed to send signals to mobile electronic devices, police departments or to central offices in order to maintain cyber security.

How long does the deployment last?

The deployment is engineered prior to installation and pre-set by the programming of the installer to deliver five, ten, or fifteen-second bursts of solution, considering the zone size and location.

Who are the users of this device?

Crotega is not responsible for the use of the threat suppression system. It is the responsibility of the building management to train and authorize users for integration into the current emergency management plans.

Does the system deploy all at once?

No, the system is set to deploy by zones which are engineered before install. Multiple zones can be deployed concurrently. Rapid deployment is possible when multiple threats are active.

Is the system part of the fire sprinkler system?

The threat suppression system is separate from fire sprinkler systems.

Is the solution deployed everywhere at once?

The threat suppression system is deployed by authorized personnel in separate zones that are set up at various locations in a building. The zones can be deployed singly or in multiples, depending on the situation.

How do the controls work and where are the controls located?

The system is controlled by a control panel located in the identified head room or other location as determined by the building owner. The touchscreen control is installed in the location determined by the building owner. Zone panic buttons or other closed contact switches are located in each zone, as determined by the building owner. Gunshot detection devices are located in each room or hallway as determined by the engineering of the system and building owner. The system is deployed upon a threat alert via the panic button or a gunshot. The system is deployed at the touchscreen upon visual recognition of the threat by a trained building occupant.

How are the tanks refilled?

The tanks are filled using the proprietary Crotega Fill Station which pumps in the Repuls solution and pressurizes the unit with air.

Can I use this system in my home?

The system can be placed in private homes, businesses, workplaces, public spaces, government buildings, schools, universities, and any location where a building owner desires a safer environment.
