Control Panel Installation

4.15.3 NFPA 72 Polarity Reversal

Note: Intended for connection to a polarity reversal circuit of a control unit at the protected premises having compatible rating.

4.15.3.1 Using the 5220 Module

When the 5220 is wired and programmed for polarity reversal, it reports alarm and trouble events to a remote site. Alarms will override trouble conditions and it will not be possible to reset the remote indicator until the condition is cleared and the control panel is reset.

If an alarm condition occurs, the alarm relay will close, overriding the trouble condition.

Standby Current:

100 mA, 24 VDC

Alarm:

100 mA, 24 VDC

To install the 5220 for polarity reversal, follow the steps below:

1.Locate the knockout on the right side of the control panel cabinet to connect the 5220 using a short piece of conduit (must not exceed 20 feet in length).

2.Wire the 5220 to the control panel using the four-wire pigtail provided as shown in Figure 4-42.This diagram also shows how to connect the 5220 to the remote indicator. Do not install an EOL resistor in the terminals of the Flexput circuit used for this application.

3.Connect earth ground wire to the 5220 chassis with mounting screw.

4.Program the Flexput circuit used as a notification circuit, continuous and non-silencing. Refer to Section 7.4.1 for zone grouping and mapping.

5.If necessary, adjust loop current using the potentiometer (R10) on the 5220 board . Normal loop current is 2-to-8 mA with a 1k ohm remote station receiving unit. Maximum loop resistance is 3k ohm.

Note:

Flexput circuit 1 and Relay 1 used as examples. Any Flexput circuit and either relay 1 or relay 2 could

be used.

All circuits power-limited.

5820XL specifications

The Honeywell 5820XL is a versatile and advanced wireless motion detector designed for residential and commercial security applications. It offers a combination of cutting-edge technology and user-friendly features, making it an ideal choice for ensuring safety and peace of mind.

One of the standout features of the Honeywell 5820XL is its advanced imaging technology. The detector employs Passive Infrared (PIR) sensing, which allows it to detect motion based on the heat emitted by objects in its field of view. This ensures high sensitivity to human movement while minimizing false alarms triggered by pets or environmental factors.

The Honeywell 5820XL is engineered with a sleek, low-profile design that can seamlessly blend into various indoor environments. Its unobtrusive presence makes it suitable for both residential homes and businesses. The device is also lightweight and compact, facilitating easy installation in various locations without compromising performance.

Another key characteristic of the 5820XL is its impressive range of detection. The unit offers a coverage area of up to 40 feet in a standard installation, ensuring a wide detection span that is effective in larger spaces. Additionally, it features a 90-degree field of view, allowing for comprehensive monitoring of hallways, rooms, and open areas.

The 5820XL is built with dual zone detection technology, which helps it distinguish between different types of motion. This not only reduces false alarms but also provides enhanced security by focusing on genuine threats. Furthermore, the detector is equipped with a tamper switch that triggers an alert if the unit is removed or tampered with, providing an additional layer of protection.

For added convenience, the Honeywell 5820XL utilizes a robust wireless communication system, ensuring a reliable connection with Honeywell security panels. The unit operates on a long-lasting battery, which minimizes maintenance and allows for uninterrupted performance.

In summary, the Honeywell 5820XL wireless motion detector combines advanced sensing technology, expansive detection range, and a sleek design to provide effective motion surveillance. Its dual zone detection, along with the tamper alert feature, adds to its functionality, making it a valuable addition to any security system. Whether for residential or commercial use, the Honeywell 5820XL stands out as a dependable choice in motion detection technology.
