Information About 70-407008-002
The 70-407008-002 is a Kidde-Fenwal SmartOne Series AI monitor module specifically configured for normally-closed contact monitoring. Its addressable electronics communicate device status over the signaling line circuit while monitoring the connected dry-contact input. The module operates from 16.5 to 27.5 VDC, draws a maximum of 450 µA, and supports connection of up to 255 addressable devices on a compatible communication circuit. Kidde-Fenwal documentation notes that the N.C. version is intended for normally-closed trouble or supervisory contact applications and is not considered an initiating device circuit for fire alarm initiation.
Key Features:
- Normally-Closed Monitoring: Designed specifically for conventional, unpowered, normally-closed contact devices.
- SmartOne Addressability: Provides an individually identifiable input point on compatible Kidde-Fenwal intelligent systems.
- Low Current Demand: Requires a maximum of 450 µA during standby and active operating conditions.
- Wide DC Input Range: Operates from a signaling circuit voltage of 16.5 to 27.5 VDC.
- High Device Capacity: Compatible communication circuits can support up to 255 addressable devices.
- Status LED: Provides operating indication with defined normal, trouble, and active-state LED behavior.
- Electrical Box Installation: Fits a 2.5-inch-deep single-gang box or a standard 4-inch square box with cover.
- Power-Limited Interface: Module terminals are designed for power-limited system wiring.
The 70-407008-002 delivers the reliability and precision required for addressable monitoring of normally-closed contacts in compatible fire protection control systems.
