5820XL is an intelligent addressable fire alarm control panel (FACP). The basic 5820XL system can be expanded by adding modules such as 5860 remote annunciator, 5815XL signalling line circuit expander, 5824 serial/parallel printer interface module (for printing system reports), and 5895XL intelligent power module. 5820XL supports SD or SK devices. 5820XL also features a powerful built-in dual line fire communicator that allows for reporting of all system activity to a remote monitoring location.

The 5820XL can be surface or flush mounted
The 5820XL signal line circuit (SLC)
supports multiple device types of the same protocol:
• SK (System Sensor)
You cannot mix SD and SK SLC devices on a FACP.
General Alarm (Red): Flashes when in alarm; solid when alarm silenced Supervisory (Yellow): Flashes when a supervisory condition exists; solid when supervisory silenced
System Troubles (Yellow): Flashes when a trouble condition exists; solid when trouble silenced
System Silenced (Yellow): On when an
alarm, trouble or supervisory condition
has been silenced but not yet cleared
System Power (Green): Flashes for AC
failure; solid when power systems are
5820XL has one built-in signalling line circuit (SLC) which supports multiple devices dependent on protocol being
used. Three additional loops can be added using the 5815XL SLC expanders to increase overall capacity. The 5820XL SLC loops support multiple device types, including:
• Addressable photoelectric smoke detector.
• Addressable ionization smoke detector.
• Addressable heat sensor.
• Addressable duct smoke detector.
• Contact module.
• Relay output module.
• Addressable notification module.
• Addressable beam detector (SK protocol only).
• Addressable multi-criteria smoke detector (SK protocol only).
• Addressable multi modules (SK protocol only).
The following advanced sensor capabilities are available with 5820XL:
• Automatic drift compensation
• Maintenance alert
• Built-in sensor test to comply with NFPA 72 calibration testing requirements.
5820XL features a 6 amp power supply and maximum battery charging capacity of 35 amp hours. An additional
cabinet enclosure (PN RBB) is required for batteries in excess of 18 amp hours. Flexput circuits on 5820XL control can be individually programmed to function as notification circuits, auxiliary power outputs, or initiation circuits that support both 2- and 4-wire smoke detectors.
The 5820XL system operates on non-twisted, unshielded cable when wired in compliance with standard wiring practices as called out in the National Electric Code 760-51 specifications for power-limited fire protective signalling
cables. No special wiring is required. 5820XL provides 13 preset notification cadence patterns (including ANSI 3.41)
and four user programmable selections for fire alarm notification. Two programmable general purpose. Form C relay outputs are provided on 5820XL. Additionally, the IntelliKnight system features a built-in walk test and auto-
programming. Its innovative, dead-front cabinet design allows for flush or surface mounting. System maintenance
is easy to perform.
The 5820XL built-in annunciator with 80 character LCD display and large easy-to-use tactile touchpad can be
used for system operation, programming and maintenance. It has five LEDs for alarm, supervisory, system trouble, system silenced and system power. System operations include silencing alarms and troubles, resetting alarms and the display of alarm troubles and memory. The system’s non-volatile event history buffer stores 1000 events for viewing from the built-in or remote annunciator System operation can be initiated with a mechanical firefighter’s key or a valid 4- to 7-digit operator’s code.
The IntelliKnight system offers several options to simplify and speed up programming. The JumpStart® feature
minimizes programming required to start a new system. The built-in keypad and 5860 remote annunciator give on-site access to all programming. You can also program remotely using the 5660 Silent Knight Software Suite, which is Windows®- based software.
Built-In Digital Communicator
5820XL features a built-in UL listed digital communicator for remote reporting of system activity and system programming. The communicator has the ability to seize two telephone lines to report alarms and troubles to a
monitoring facility. The communicator supervises two phone lines and will activate a trouble signal if a line failure
is sustained for more than 45 seconds. Other communication features include:
retry if communication fails, two phone number capability, download phone number capability and Touch-Tone or
rotary dialing.The communicator is compatible with SIA and Ademco Contact ID.The format is selectable by account number.
