A User ID is a user name and password that can be used to access several Honeywell Web sites.
You must first provide some basic account information. All fields marked with an asterisk * or "Thumbs down/up" symbol are required and include an easily-remembered User ID, Password, First name, Last name, and Email address. To help protect your account, you must also provide three Security Questions and Answers. You provide the Password, Email address, and each Security Answer twice to help avoid accidental typos.
The VESDA VLS detector has an alarm sensitivity range of 0.005%–20% obscuration/m (0.0015%–6.25% obscuration/ft). The VLS is classed as a “Very Early Warning Smoke Detector”, which means that it detects fire at the earliest possible stage and reliably measures very low to extremely high concentrations of smoke.
The detection chamber uses a stable Class 1 laser light source and carefully positioned sensors to achieve the optimum response to a vast range of smoke types. The status of the detector, and all alarm, service and fault events, are transmitted to displays and external systems via VESDAnet.
It also includes a valve mechanism in the inlet manifold and software to control the airflow from the four sectors (pipes). This configuration enables a single VESDA zone to be divided into four separate sectors, for example, distinguishing between separate voids within a room.
