ACM-24AT Auxiliary Display Unit

The ACS Series ONSX provides LED and switch modules to annunciate status and control fire alarm panels, network controllers, or specific system output circuits.

FMM-1 Monitoring Module

The FMM-1 module monitors dry-contact devices like flow switches and manual call points, transmitting their operational status back to the main fire alarm control panel.

24V FCM-1 Control Module

The FCM-1 addressable module provides 24V DC power for sirens and speakers, allowing activation manually or via the fire alarm control panel's programming software.

The SSM24-6 Non-Addressable Bell is a 6-inch sounder operating at 24VDC, with a loud output (~82dB), used for wired fire/burglar alarm systems, featuring polarized design, easy installation, and reliability.

FRM-1 Relay Control Module

The FRM-1 addressable module provides dry contact outputs to control peripheral devices, enabling activation either manually or via fire alarm control panel programming software.

FZM-1 Conventional Detector Connection Module

The FZM-1 conventional detector connection module is used to interface with and monitor 2-wire conventional detectors. The status (on, off, alarm) of a detector zone will be sent to the control panel for monitoring.

ISO-X Isolation Module

The ISO-X isolation module is used in the Onyx fire alarm system to protect the system against short circuits on the SLC loop.

Addressable Emergency Push Button FSM500K/T(E)

This modern smoke detector meets UL268 standards, featuring dual LEDs for 360-degree visibility, rotary decimal addressing, and anti-interference technology to ensure maximum safety.

5601P Rate of Heat Detector

The 5601P heat detector is a key component in conventional fire alarm systems for industrial, apartment, and commercial buildings, offering high safety and cost-effectiveness, used where smoke detectors cannot be installed.

NBG-12LX Addressable Emergency Push Button

Addressable pull stations actively trigger early alarms during emergencies. They provide precise location data to the control panel, enabling responders to quickly reach the alert area.

System Sensor 885 Conventional Heat Detector

Features an LED indicator for alarm status (normally the light is off, but turns red when an alarm occurs). Includes a terminal for a room indicator light.

System Sensor 882 Conventional Smoke Detector

Features an LED indicator for alarm status (normally the light is off, but turns red when an alarm occurs). Includes a terminal for a room indicator light.
