Audio, Visual, Indication – Combines integrated detectionand control capabilities in one compact and lightweight unit
The Delta AVI fire detection system is comprised of:
• The DELTA linear detector: Enhances fire detection reliability by measuring both the rate of temperature rise as well as the absolute temperature change above ambient conditions. The sensor sensitivity can be calibrated according to the protected zone’s environmental conditions.
• The DELTA 6 AVI: A lightweight, compact, user-friendly control unit that receives the signals from the linear detector. Permitted thresholds can be configured for rate of temperature rise and/or absolute temperature so that the control unit can drive “Pre Alarm” and “Fire Alarm” relays to activate fire suppression mechanisms. The control unit also provides audio and visual Fire, Fault and Power indications. Fire events, faults and signal peaks are stored in the control unit’s non-volatile memory, and can be downloaded at any time through a USB interface.
