Table 7-1: Alarm Delay Characteristics

 

 

Type of Delay

Description

 

 

 

 

 

One Count (No Delay). When this option is enabled, an alarm occurs immediately when a single device

1-Count

of any of the following types goes into alarm: detector, manual pull, water flow, Aux1 or Aux2. This is

 

considered the most typical operation and is the default for all zones.

 

 

 

When this type of alarm delay is used, two or more detectors within the zone must go into alarm in order

 

for the zone to report an alarm. Switches of type manual pull, water flow, Aux1 and Aux2 are an

 

exception; they will cause an alarm when only one switch is in alarm.

2-Count

When a single detector is in alarm in a 2-Count zone, the system enters a prealarm condition. In a

 

prealarm condition, the touchpad PZT beeps and the annunciator display indicates that a prealarm has

 

occurred. If the zone has been mapped to an output group for the prealarm event, the output group will

 

activate. The prealarm will not be reported to the central station.

 

 

 

Alarm verification is an optional false alarm prevention feature that verifies an alarm condition by

Alarm Ver.

resetting the smoke detector. If the alarm condition still exists by the time the reset cycle has completed,

the detector will go into alarm. If the detector is no longer in alarm, no report will go to the central

 

 

station. The alarm verification sequence is ignored if the zone is already in alarm.

 

 

 

This option is intended to be used with an acknowledge switch. An alarm is delayed for 15 seconds,

 

giving on-site personnel a chance to investigate the alarm. If the acknowledge switch is not activated

 

within 15 seconds, an alarm occurs automatically.

 

If this option is enabled for a zone, the zone will respond to an alarm condition as follows:

 

• The zone will not go into alarm for 15 seconds to allow an on-site operator to activate the acknowl-

 

edge switch.

PAS

• If the operator does not press the acknowledge switch within 15 seconds, the zone will go into

 

alarm.

 

• If the operator presses the acknowledge switch within 15 seconds, a 180-second time-frame will

 

begin counting down. This time-frame allows the operator to investigate the cause of the alarm.

 

If the operator performs a reset within 180 seconds, the alarm will not occur. If the operator does

 

not perform a reset within 180 seconds, an alarm will occur automatically.

 

• The P.A.S. feature will be overridden if another alarm occurs.

 

 

SNGL ILOCK

See Section 8.7.1 for single interlock releasing operation.

 

 

DBL ILOCK

See Section 8.7.2 for double interlock releasing operation.

Heat Temperature Setting

Use this feature to set the temperature at which heat detectors will respond. The range is 135° to 150° F. All detectors in the zone will respond in the same way.

The Model SD505-AHS Heat Detector is an absolute temperature device. This means that it responds to an alarm immediately if the temperature in the zone goes above the programmed temperature.

5.Enter the temperature at which the heat detector will respond. Or

Use the or keys to scroll through the range or enter directly from the number keys

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.
