Firecom F900-790 XP95A Dual Input Monitor Module

The Firecom F900-790 XP95A Dual Input Monitor Module is an intelligent addressable module designed to provide two independent initiating device circuits for monitoring dry-contact devices within compatible XP95A fire alarm systems. The Firecom F900-790 allows conventional initiating devices such as pull stations, waterflow switches, supervisory switches, and other contact devices to be integrated into an addressable fire alarm network. Therefore, it provides reliable monitoring and reporting of multiple field devices while reducing installation costs and conserving loop addresses.

Firecom F900-790 Function

The F900-790 is designed to monitor two separate initiating device circuits and report alarm or supervisory conditions to the fire alarm control panel. As a result, each monitored circuit can be individually identified and supervised through the addressable signaling loop. In addition, the module continuously monitors field wiring integrity and communicates device status back to the control panel.

Dual Input Monitoring Capability

The Firecom F900-790 incorporates two independent monitored inputs within a single addressable module. Consequently, system designers can connect two initiating device circuits while using only one addressable device location. Furthermore, the dual-input design helps reduce wiring complexity and overall system hardware requirements.

Class B and Class A Wiring Support

The module supports both:

• Style B (Class B) Initiating Device Circuits
• Style D (Class A) Initiating Device Circuits

Therefore, installers can select the wiring configuration that best meets project requirements and applicable fire alarm codes. Additionally, Class A wiring provides enhanced survivability in critical life safety applications.

Addressable XP95A Communication

The F900-790 is designed for operation on XP95A addressable fire alarm loops. As a result, each monitored circuit is individually supervised and identified by the control panel. Moreover, addressable communication improves troubleshooting, maintenance, and event reporting by providing precise device location information.

Supervision of Contact Devices

The Firecom F900-790 is commonly used to monitor:

• Manual pull stations
• Waterflow switches
• Valve tamper switches
• Supervisory switches
• Pressure switches
• Conventional alarm contacts
• Security contacts
• Building monitoring devices

Consequently, it provides a flexible interface between conventional field devices and intelligent fire alarm systems.

LED Status Indicators

The module includes two LED indicators that blink during communication with the fire alarm control panel. Therefore, technicians can quickly verify normal operation and communication status. Additionally, the LEDs can be programmed to illuminate steadily when the associated circuit enters an alarm condition.

Low Power Consumption Design

The F900-790 utilizes a low-current design that minimizes load on the signaling loop. As a result, system capacity can be optimized while maintaining reliable operation. Furthermore, reduced power requirements support larger installations with multiple addressable devices.

Simplified Installation

The module is designed for installation within a standard 4-inch square electrical box or double-gang electrical enclosure. Consequently, installation is straightforward and compatible with common electrical infrastructure. Additionally, DIP switch addressing allows fast and accurate device configuration.
