1. Introduction

This manual provides essential information for the proper installation, operation, and maintenance of the System Sensor APA151 Remote Annunciator with Piezo Alarm. Please read this manual thoroughly before attempting to install or operate the device.

The APA151 is designed to provide remote audible and visual annunciation for compatible fire alarm control panels or other signaling systems. It features a piezo alarm for audible alerts and indicator lights for power and alarm status.

2. Product Overview

Figure 1: Front view of the System Sensor APA151 Remote Annunciator. This image displays the front of the System Sensor APA151 Remote Annunciator. It features a white rectangular casing with a speaker grille in the center. Below the grille, there are two indicator lights: a green LED labeled 'POWER' on the left, and a red LED labeled 'ALARM' on the right. Two screws are visible, one at the top and one at the bottom, securing the device. The bottom also has text 'DO NOT PAINT FIRE ALARM DEVICE'.

The System Sensor APA151 is a compact, white-finished remote annunciator designed for indoor use. It integrates a piezo alarm for audible notification and two LED indicators: a green LED for power status and a red LED for alarm status. The device is typically mounted in a single gang box and is compliant with UL standards.

3. Setup and Installation

3.1 Mounting

• The APA151 is designed for single gang box mounting.
• Ensure the mounting location is clean, dry, and within the specified ambient temperature limits (32 to 120°F / 0 to 49°C).
• Secure the annunciator to the single gang box using the provided screws.
• A pendant mount option may also be available or included, depending on the specific product configuration.

3.2 Electrical Connections

• The device operates on a voltage range of 16 to 33 VDC.
• Connect the annunciator to a compatible fire alarm control panel or signaling device. Refer to the control panel's manual for specific wiring diagrams and connection points.
• Ensure all wiring complies with local electrical codes and standards.
• The alarm current draw is approximately 30mA. Ensure the power source can supply this current in addition to other connected devices.

4. Operation

Once properly installed and powered, the APA151 Remote Annunciator will operate as follows:

• Power Indicator (Green LED): This LED illuminates when the device is receiving adequate power from the connected system.
• Alarm Indicator (Red LED): This LED illuminates when an alarm condition is detected by the connected control panel.
• Piezo Alarm: Upon an alarm condition, the integrated piezo alarm will emit an audible tone to alert occupants. The alarm will sound concurrently with the illumination of the red alarm LED.

The specific behavior of the alarm (e.g., continuous, temporal pattern) is typically controlled by the connected fire alarm control panel.

5. Maintenance

To ensure the continued reliable operation of your APA151 Remote Annunciator, follow these maintenance guidelines:

• Cleaning: Periodically clean the exterior of the annunciator with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Inspection: Regularly inspect the device for any visible damage or obstructions to the speaker grille.
• Testing: Conduct periodic functional tests in accordance with local codes and the recommendations of the connected fire alarm control panel manufacturer. This typically involves initiating an alarm condition to verify both visual and audible annunciation.
• Painting: As indicated on the device, DO NOT PAINT FIRE ALARM DEVICE. Painting can interfere with the device's functionality and visibility of indicators.

6. Troubleshooting

If the APA151 Remote Annunciator is not functioning as expected, consider the following:

• No Power Indicator (Green LED Off):
  • Verify that the annunciator is receiving the correct voltage (16-33 VDC) from the control panel.
  • Check all wiring connections for proper termination and continuity.
  • Ensure the control panel itself is powered and functioning correctly.
• No Alarm Indicator (Red LED Off) or No Piezo Alarm during an alarm condition:
  • Confirm that the control panel is indeed in an alarm state and is configured to activate the remote annunciator.
  • Check wiring between the annunciator and the control panel for breaks or incorrect connections.
  • Ensure the annunciator's power indicator (green LED) is on.
• Intermittent Operation:
  • Inspect wiring for loose connections or damaged insulation.
  • Check for environmental factors such as extreme temperatures or humidity outside the specified limits.

For persistent issues, consult the manual of the connected fire alarm control panel or contact System Sensor technical support.
