Description
The Aritech DP721RTA is a 700 series conventional multi detector w/ relay output and auto reset functionality. All Aritech 700 series smoke detectors continuously monitor their sensitivity and operational status. Background drift is daily compensated to maintain the original calibrated sensitivity within the required limits.
Once a day the detector performs a full diagnostic test that includes dynamically testing the sensing chamber and internal electronics. If a detector drifts out of sensitivity range or fails the internal diagnostics test, this is reported back to the panel and indicated on the detector with a yellow fault LED.
The Right Detector For The Job
For a truly fast and broad-spectrum detection the DP721RTA offers both optical and heat sensors. The interaction of both the smoke and heat algorithms ensure a quick response to both flaming and smoldering fires.
All bases are provided with an integral locking tab for extra security if required. Bases are equipped with a shorting bar between IN and OUT that opens when the head is installed and that may be manually restored when removing the head. This simplifies cable continuity testing.
Maintenance Friendly Sensitivity Level Test Mode
The 700 Series photoelectric detectors include a sensitivity test mode that may be activated by simply holding a magnet near the detector’s test point. This initiates a self-diagnostic routine and provides visual indication if service is required. This test mode allows field sensitivity testing without the requirement for external meters or test gas.
Aritech DP721RTA 700 Series Conventional Multi Detector has the following features:
- Floating background with drift compensation
- Separate fire and fault LEDs
- 12-24VDC operation
- Polarity insensitive
- COM/NO/NC contacts for easy supervision on any system
- Automatic reset when event clears
The DP721RTA must not be used in applications requiring compliance with commercial or residential fire standards such as EN54-5/EN54-7/EN54-29/CEA4021/EN14604. Always ensure compliance with local codes and standards.
