The Apollo XP95 Interfaces offer a practical and reliable solution for commercial buildings, hospitals, hotels, offices, warehouses, schools, residential developments, and industrial facilities. Designed as intelligent interface devices, they help connect compatible fire alarm control panels with external monitoring devices, conventional circuits, relay-controlled equipment, and other building safety systems.
For fire protection contractors, engineers, system integrators, building owners, and maintenance teams, choosing the correct Apollo XP95 Interface can help improve system coordination, provide accurate device monitoring, simplify fault identification, and support dependable fire alarm operation.

What Are Apollo XP95 Interfaces?
The Apollo XP95 Interfaces are addressable modules designed to connect external equipment and non-addressable circuits to a compatible Apollo fire alarm system.
Depending on the selected interface model, the device may be used to:
Monitor external switches and contacts
Control auxiliary equipment through relay outputs
Connect conventional detectors to an addressable loop
Monitor fire protection equipment status
Supervise external circuits
Integrate fire alarm functions with building systems
Each compatible interface communicates its condition to the fire alarm control panel, helping operators identify alarms, faults, supervisory signals, and equipment-status changes.
Key Benefits of Apollo XP95 Interfaces
Reliable System Integration
The Apollo XP95 Interfaces help connect different fire protection and building systems to one addressable fire alarm network. This allows the fire alarm control panel to monitor or control external equipment based on the approved system design.
Addressable Monitoring
Each interface is assigned an individual address within the fire alarm system. This helps the control panel identify the exact interface or connected circuit associated with an alarm, fault, supervisory condition, or equipment activation.
Flexible Input and Output Options
Apollo offers interface modules for different system requirements. Depending on the model, an interface may provide:
Monitored inputs
Relay outputs
Combined input and output functions
Conventional zone monitoring
Sounder circuit control
Equipment-status monitoring
This flexibility allows engineers to select the proper device for a specific fire alarm application.
Helps Control External Equipment
Selected Apollo XP95 output interfaces can provide relay contacts for controlling compatible equipment such as fire doors, smoke-control systems, ventilation equipment, elevators, access-control systems, and auxiliary alarm devices.
The relay rating and connected equipment requirements must always be checked before installation.
Supports Conventional Device Integration
Certain Apollo interfaces allow compatible conventional detectors or devices to be connected to an addressable fire alarm system. This can be useful for system expansion, renovation, or upgrading an existing conventional installation.
Organized and Space-Saving Installation
DIN-rail interface modules can be installed inside a suitable electrical or fire alarm enclosure. This helps maintain organized wiring and provides convenient access for inspection, testing, and maintenance.

How Do Apollo XP95 Interfaces Work?
The Apollo XP95 Interface communicates with the compatible fire alarm control panel through the addressable detection loop.
For an input application, the interface monitors the status of an external contact or circuit. When the connected equipment changes condition, the interface sends the corresponding signal to the fire alarm control panel.
For an output application, the fire alarm control panel sends a command to the interface. The interface then activates its relay output to control the connected equipment.
This communication allows the fire alarm system to perform programmed actions based on the approved cause-and-effect sequence.
Common Applications of Apollo XP95 Interfaces
An Apollo XP95 Interface may be considered for the following applications:
Commercial buildings
Hospitals and healthcare facilities
Hotels and accommodation buildings
Offices and business facilities
Warehouses and logistics centers
Schools and universities
Residential developments
Industrial plants
Data centers
Shopping centers
Transportation facilities
Mechanical rooms and pump rooms
Fire alarm system expansion projects
Building management system integration
Equipment Commonly Connected to Apollo Interfaces
Depending on the interface type and approved system design, Apollo interfaces may be connected to:
Sprinkler waterflow switches
Alarm pressure switches
Valve supervisory or tamper switches
Fire pump status contacts
Conventional smoke and heat detectors
Fire doors and door holders
Smoke-control dampers
Ventilation shutdown controls
Elevator recall systems
Access-control systems
Gas suppression systems
Building management systems
External sounders and warning devices
Equipment alarm and fault contacts
Why Choose an Apollo Input Interface?
An Apollo input interface is commonly selected when the fire alarm system needs to monitor an external switch, dry contact, or equipment-status signal.
When the connected contact changes condition, the interface reports the event to the control panel. This allows the system to monitor equipment such as waterflow switches, pressure switches, valve tamper switches, fire pump controllers, and mechanical system contacts.
Why Choose an Apollo Output Interface?
An Apollo output interface is used when the fire alarm system needs to control compatible external equipment.
When an alarm or programmed event occurs, the control panel can command the interface relay to perform a specific function, such as:
Releasing a fire door
Shutting down ventilation equipment
Activating smoke-control equipment
Sending a signal to a building management system
Initiating elevator recall
Activating an auxiliary alarm circuit
An appropriately rated relay or contactor may be required when the connected electrical load exceeds the interface relay capacity.
Why Choose a Combined Input/Output Interface?
A combined input/output interface provides both monitoring and control functions in one device.
This type of interface can help reduce the number of separate modules required for an installation. It may monitor the status of external equipment while also controlling another connected device based on the programmed fire alarm sequence.
Combined interfaces are useful in applications requiring coordinated equipment monitoring and activation.
Important Considerations Before Buying
Before selecting an Apollo XP95 Interface, it is important to confirm the following:
Required interface type
