The detector’s on-board detector only needs to communicate with the loop controller when microprocessor measures and analyzes these signals. It compares it has something new to report. the information to historical readings and time patterns to make an alarm decision. Digital filters remove signal patterns that are not typical of fires. Unwanted alarms are virtually eliminated.

The detector’s sensitiv- ity measurement can also be transmitted to the loop controller. A sensitivity report can be printed to satisfy NFPA sensitivity meas- urements which must be conducted at the end of the first year and every two years thereafter. The user-friendly maintenance program shows the current state of each detector and other pertinent messages. Single detectors may be turned off temporarily, from the control panel. Availability of maintenance features is dependent on the fire alarm system used. Scheduled maintenance (Regular or Selected) for proper detec- tor operation should be planned to meet the requirements of the Authority Having Jurisdiction (AHJ). Refer to current NFPA 72 and ULC CAN/ULC 536 standards. Compatibility The SIGA-IS detectors are compatible only with EST’s Signature Loop Controller.

Issue 8 Application Although ionization detectors have a wide range of fire sensing capabilities they are best suited for detecting slow, smoldering fires. The table below shows six standard test fires used to rate the sensitivity of smoke and heat detectors. The table indicates that no single sensing element is suited for all test fires. Edwards recommends that this detector be installed according to latest recognized edition of national and local fire alarm codes.
