- Public Client Docs and the Support Library can be read without signing in.
- A verified client account is required to create a portal ticket and view account-specific history.
- Email helpdesk@detection-systems.com when email intake is more convenient or a portal problem prevents ticket creation.
Choose the correct entry point
- Create Service Request: sign in, create one complete request, and keep the confirmation ticket number.
- Check Request Status: use the original request email address and the DSE ticket number to request a secure access link.
- Support Library: search public, customer-safe guidance before or after opening a ticket.
- Client Docs: use these detailed instructions for account, ticket, security, scheduling, business, and mobile workflows.
What clients can do from the home page
- Sign in with a verified client account and open a new DSE support ticket.
- Check the status of an existing ticket.
- Open the public Support Library and client documentation.
- Sign in when you need to create a portal ticket, view ticket history, read private replies, or use account-specific information.
Recommended first step
- If the issue is new, sign in and select Create Service Request or Open a New Ticket.
- If DSE already gave you a ticket number, select Check Request Status.
- If you are not sure what to send, open the Support Library first.
