It provides real-time status reporting and supports Verifire® programming for flexible system integration.     Technical Specifications  Condition New/Never Used Surplus Brand Notifier Category Fire Safety Part Number UDACT-2 Subcategory Fire Alarm Control Power Input 24 VDC (regulated), 21.2–28.2 VDC range Standby Current 40 mA Current While Communicating 75 mA Max Current (relay activated) 100 mA Programming Interface USB and EIA-485 (VeriFire Tools) Reporting Capacity Up to 2,040 points Phone Line Support Dual line supervision with voltage detect Message Rate 14 point trouble messages/hour Communication Formats Ademco Contact ID (required), 4+2 Standard, SIA Mounting Options Panel or remote in ABS-8RB, UBS-1B/R UL Listed Receivers Ademco 685, MX8000, SurGard MLR2, Silent Knight, etc. Agency Approvals UL, FM, CSFM, FDNY Dimensions 6.75" x 4.25" (17.145 x 10.795 cm) Weight 0.10 lbs       Information About UDACT-2 The UDACT-2 is engineered to transmit system status, including alarms, troubles, supervisory signals, and power losses, from Notifier control panels to a central station. It supports both modern and legacy panels—such as NFS-3030, NFS2-3030, NFS2-640, and the NCA-2 annunciator—and can report up to 2,040 points via the Ademco Contact ID protocol. The module supports dual phone lines with line voltage detection, helping ensure reliable communication under all conditions. Programming and firmware updates are completed via VeriFire® Tools through USB or serial port. The device includes an EIA-485 interface to the host panel and supports real-time clock stamping, extensive event annunciation (manual test, AC fail, battery loss, etc.), and transmission of up to 14 trouble messages per hour. It can be mounted in the panel or in a remote ABS/metal enclosure and is approved by UL, FM, CSFM, and FDNY. Key Features: Wide System Compatibility: Works with Notifier NFS-series panels, legacy models, and the NCA-2 annunciator. High-Capacity Reporting: Supports reporting for up to 2,040 points using Ademco Contact ID format. Dual Phone Line Monitoring: Includes line voltage detection and auto-switching between two phone lines. USB and EIA-485 Interfaces: Allows easy programming and integration via VeriFire® Tools. Multi-Zone Signal Support: Transmits alarm, trouble, supervisory, bell trouble, battery loss, and AC fail conditions. Flexible Mounting Options: Installs in-panel or remotely using ABS or metal enclosures (ABS-8RB, UBS-1B/R). Event Annunciation & Testing: Includes test signals, kiss-off timers, line seize indicators, and communication fail status. Low Power Consumption: Draws just 40 mA standby, 75 mA during communication. Real-Time Clock and Relay Output: Tracks events accurately and supports open-collector relay driver for failure alerts. UL Listed Receiver Compatibility: Approved for use with Ademco, SurGard, Radionics, FBI CP, and other central station receivers. The UDACT-2 enables centralized monitoring of fire alarm events with high-capacity communication, protocol flexibility, and reliable phone-line supervision.
