Honeywell ASD-PTL3 Smoke Detector with Thermal Sensing

The Honeywell ASD-PTL3 Smoke Detector with Thermal Sensing is an intelligent addressable detector from the Gamewell-FCI Velociti Series 3 family. It combines photoelectric smoke detection with supplemental thermal sensing using dual electronic thermistors, providing both smoke and heat detection in a single low-profile device.

The ASD-PTL3 communicates directly with compatible Gamewell-FCI fire alarm control panels, providing point identification for alarm reporting, troubleshooting, and maintenance. Each detector is assigned a unique address using built-in rotary switches, allowing the system to identify the exact device in alarm or trouble conditions.

Photoelectric Smoke Detection

The ASD-PTL3 uses a redesigned photoelectric optical sensing chamber designed to detect a wide range of combustion products.

Photoelectric detection is especially effective for smoldering fire conditions, where larger smoke particles are produced. The Series 3 optical chamber was redesigned to meet the enhanced performance requirements of UL 268 7th Edition.

The detector continuously communicates with the fire alarm control panel, allowing the system to identify the exact device in alarm and respond accordingly.

135°F Thermal Detection

In addition to smoke detection, the ASD-PTL3 includes thermal detection using dual electronic thermistors.

• Fixed Temperature Threshold: 135°F (approximately 57°C)

The thermal sensing element provides an additional detection method within the same device, allowing the detector to respond to elevated heat conditions even in the absence of visible smoke.

This dual-technology design distinguishes the ASD-PTL3 from smoke-only models in the same Series 3 family.

Intelligent Addressable Operation

The ASD-PTL3 is an intelligent addressable detector with full point identification capability.

Each detector is assigned a unique address on the signaling line circuit (SLC). When an alarm occurs, the control panel identifies the exact detector rather than only a general zone.

This enables:

• Precise alarm location identification
• Faster troubleshooting
• Improved maintenance efficiency
• Enhanced system diagnostics
• Accurate detector-level reporting

The detector also continuously reports temperature data to the control panel for system monitoring.

Rotary Addressing

The ASD-PTL3 uses built-in rotary address switches for device programming.

• Address Range: 01–159

The installer sets the address directly on the detector before system commissioning. Each device must have a unique address to ensure proper system operation.

Correct addressing is essential for accurate point identification and system programming.

Programmable Sensitivity

The ASD-PTL3 supports programmable smoke sensitivity through compatible Gamewell-FCI control panel software.

This allows sensitivity levels to be adjusted based on:

• Environmental conditions
• Occupancy type
• Airflow characteristics
• System design requirements
• Applicable fire protection codes

Proper sensitivity configuration ensures reliable detection while minimizing nuisance alarms.

Status LEDs

The detector includes dual LEDs positioned for 360-degree visibility.

These LEDs provide clear visual indication of device status and assist with:

• System commissioning
• Alarm identification
• Maintenance and inspection
• Troubleshooting
• Functional testing

LED behavior is controlled by the fire alarm control panel.

Magnetic Functional Test

The ASD-PTL3 includes a built-in functional test feature that can be activated using an external magnet.

This allows technicians to simulate an alarm condition without removing the detector from its base.

Functional testing must be performed in accordance with manufacturer instructions and applicable inspection requirements.

Detector Base Options

The ASD-PTL3 is compatible with a range of Velociti Series bases, allowing flexibility in system design.

Supported base types include:

• Standard mounting bases
• Relay bases
• Isolator bases
• Sounder bases

A common compatible base is the B300-6 low-profile 6-inch mounting base.

The detector head and base must always be selected according to system requirements and approved Gamewell-FCI configurations.

Electrical Specifications

• System Voltage: 24 VDC
• SLC Standby Current: 200 µA
• SLC Alarm Current: 4.5 mA
• Address Range: 01–159
• System Type: Intelligent addressable

Actual device loading depends on the control panel, SLC configuration, and system design.

Color & Appearance

• Standard Color: Bright white
