General Description

The SpectrAlert Advance series of notification appliances offers a comprehensive range of red and white wall, ceiling, and outdoor products including horns, strobes, and horn/ strobes. These products are electrically backward compat- ible with the previous generation of notification appliances. While there are products specifically designed for use on the ceiling or the wall, the products are listed to be used in either application, i.e., wall products could be used on the ceiling. SpectrAlert products are designed to be used in either 12 or 24 volt DC or full wave rectified (FWR) sys- tems. If required, the MDL module may be used in order to provide synchronization.

NOTICE: This manual shall be left with the owner/user of this equipment.

Fire Alarm System Considerations

The National Fire Alarm Code, NFPA 72, requires that all horns, used for building evacuation installed after July 1, 1996, produce temporal coded signals. Signals other than those used for evacuation purposes do not have to produce the temporal coded signal.

Power Supply Considerations

Panels typically supply DC filtered voltage or FWR (full wave rectified) voltage. The system design engineer must calculate the number of units used on a loop based on the type of panel supply. Be certain the sum of all the device currents does not exceed the current capability of the panel.

Calculations are based on using the device current found in the subsequent charts and must be compatible with the current specified for the panel or power supply used.

Wire Sizes

The designer must be sure that the last device on the circuit has sufficient voltage to operate the device within its rated voltage. When calculating the voltage available to the last device, it is necessary to consider the voltage drop due to the resistance of the wire. The thicker the wire, the smaller the voltage drop. Generally, for purposes of determining the wire size necessary for the system, it is best to consider all of the devices as “lumped” on the end of the supply circuit to simulate worst case. For the most accurate voltage drop calculations use the System Sensor voltage drop calculator available on the web or CD-ROM.

Approximate wire resistance:

18 AWG solid: 8 ohms/1000 ft.

16 AWG solid: 5 ohms/1000 ft.

14 AWG solid: 3 ohms/1000 ft.

12 AWG solid: 2 ohms/1000 ft.

NOTE: If Class A wiring is installed, the wire length may be up to twice as long as on non-fault tolerant circuits.

NOTE: For 24 volt applications, the total number of strobes on a single NAC must not exceed 40, with a maximum loop resistance of 120 ohms. For 12 volt applications, the total number of strobes must not exceed 12, with a maximum loop resistance of 30 ohms.

P2R specifications

System Sensor P2R is a state-of-the-art photoelectric smoke detector designed for advanced fire detection applications. This innovative device utilizes cutting-edge technology to ensure maximum reliability and performance in various environments. One of its main features is the incorporation of a dual chamber photoelectric sensing technology, which enhances its ability to detect a wide range of smoke particles, particularly those generated by smoldering fires.

The P2R is equipped with advanced algorithms that can differentiate between real fire signatures and false alarms, significantly reducing nuisance alarms that can lead to unnecessary disruptions. With a sophisticated signal processing capability, the detector can analyze the particulate matter present in the air and provide a more accurate response, making it suitable for both residential and commercial properties.

Another notable characteristic of the System Sensor P2R is its compatibility with a variety of fire alarm control panels. This ensures seamless integration into existing fire alarm systems, enhancing the overall safety measures in place. The detector communicates with other devices in the system using advanced wireless protocols, allowing for easy installation and efficient communication without the need for extensive wiring.

An additional feature of the P2R is its built-in sounder, which generates a loud alarm to alert occupants in the event of smoke detection. This is particularly useful in larger spaces where a visual indicator alone may not be sufficient. The device also incorporates a test button that allows users to easily check the functionality of the unit, ensuring that it is always in optimal working condition.

Moreover, the P2R is designed with a long-lasting power supply, requiring less frequent battery changes. This not only enhances its reliability but also reduces maintenance costs over time. The device is constructed with materials that ensure durability and can withstand varying environmental conditions, making it an ideal choice for diverse installations.

In summary, the System Sensor P2R is a highly advanced photoelectric smoke detector featuring dual chamber technology, intelligent algorithms, and compatibility with existing fire alarm systems. Its built-in sounder, easy testing capabilities, and robust design contribute to its reputation as a reliable solution for effective fire detection, making it an essential component in safeguarding lives and property.
