How to Recover Fire Alarm System Information

Introduction

This bulletin is intended to assist in recovering information from a functioning EST fire

alarm control unit when the project database file is not available. This may occur when

an original installing dealer has gone out of business, when an owner has ended the

relationship with the service company, or when there are legal or other reasons that the

project database file cannot be made available.

NFPA Code requires involving the AHJ before modifying an existing Life Safety System.

The following is from the 2010 edition of NFPA 72:

10.18.1.1 The authority having jurisdiction shall be notified prior to installation or

alteration of equipment or wiring.

Project database files

Per NFPA code, the system installer is required to leave a copy of the system database

with the owner.

The following is from the NFPA 72 2010 edition:

10.18.2.3 Documentation Required. Every system shall include the following documentation,

which shall be delivered to the owner or the owner’s representative upon final acceptance of thesystem:

(1)*An owner’s manual and manufacturer’s published instructions covering all system equipment

(2) Record drawings

(3) For software-based systems, record copy of the site-specific software

(Explanation from NFPA Handbook) The Code requires in 10.18.2.3(3) that a record copy ofthe site-specific software be delivered to the owner or the owner’s representative upon final

acceptance of the system. Having a backup copy of the software will help facilitate reconfiguringthe system in situations where catastrophic failure has occurred due to lightning or other causes.Refer to the definition of site-specific software in 3.3.255.2. The site-specific software is the

programming of the system for its specific application. It is not the executive software or thesource code used to develop the site-specific software.

The ideal method to work on a system that has been abandoned is to attempt to get acopy of the latest system database file. If the former service company is still inbusiness, it is worth you or the building owner contacting them to request a copy of thedatabase file. If you have a good relationship with the Fire Marshall, it may be worthgetting him or her involved. A call from the FM to the former service company may

convince them to comply with the requirement to leave the project file with the facilityowner.

Retrieving point lists from addressable panels

All addressable panels will have some method of displaying and possibly printing

troubles and faults as they occur. The simplest procedure is to lift the communication

loop from one of the addressable loop controller modules and then write down or

capture this trouble report in some manner. When the loop finishes reporting all of the

troubles, replace the wires that were removed and wait for those troubles to clear, and

then continue with any additional loops. This process will normally provide a list of each

point address, the basic type of device, and any assigned user message for that point.If the panel has hardwired NACs (Notification Appliance Circuits) or relay modules with

shutdowns, they should be disabled before lifting the addressable loop to prevent

unwanted alarms or preventable interruptions to normal building operations.

Once completed, you will have a list that should identify all detectors, pull stations,

waterflow switches, tampers and other input devices. It may also indicate any field

NACs, shutdowns or other functions.

Note that the EST2 and EST3X have a built-in RS-232 port which can be used with

HyperTerminal to capture the SIGA Loop information from the either a report or when

lifting the loop wires.The EST3 requires the RS232 Card to be installed on the 3-CPU before the data can be

captured to HyperTerminal. If none of the panels on the network have an RS-232 card,

you could power the panel down and temporarily install one. This would allow you to

use HyperTerminal to capture the text.

Another source of information is the CMS point assignments. This may include zone or

other information that was included to provide critical data to dispatched responders.

Programming QuickStart and iO panels

These panels have the capability of retrieving the field devices, panel configuration and

program as stored in the system. Note that the program may not match exactly with the

way it was originally written as the CU may have optimized the programming before

downloading.

Retrieving Loop Data from EST2, 3X and EST3 panels

The SDU for these panels support retrieving the Signature device data while connected

to the panel. This is necessary to allow mapping and loop reconciliation but also

provides us with a method to populate the SDU with the actual installed devices in an

unknown system.Once at the site, open the SDU program and create a startup SDU project with all of the

cabinets and panel modules as they exist at the site. Make sure to get all the modules

including plug in option cards on the back, any operator layers and note the voltage

settings of any amplifiers. You will also need to determine the existing panel node

addresses to make sure your new project matches the existing to prevent

communication issues. (Note: this bulletin assumes familiarity with the SDU

procedures for SIGA loop retrieval by EST certified technicians).

Once the map is uploaded, “Accept All” from the map screen and those devices will get

loaded into the loop configuration. Now the project will have the Device Type,

personality and address.

Programming EST2, 3X and EST3 panels

Only the loop data is able to be retrieved from these systems. This data does not

include programming rules or object labels. This is because the panels do not store the

rules and object labels as we understand them. The SDU requires that you compile the

project before downloading which interprets the rules and the objects affected by the

rules, and converts those into a code that the CPUs in the panels and loop controllers

can understand. This process results in the database files that are stored into the panel

memory during download.

Since the programming cannot be retrieved from these panels, there are two options:

1. Perform a complete test and inspection of the system to create a record of the

following outputs for each input or fire zone:

a. Notification appliances

b. Voice Messages or coded tones (if used)

c. Relays and other outputs

d. CMS reporting to monitoring servicese. Any other specific outputs that need to occur for this system

2. If the owner and the AHJ agree, the system can be evaluated as a new system.

This means having detailed discussions regarding the required sequence of

operation for the site. If the old service company was having problems

maintaining and programming the system, re-evaluating the required system

functionality may be the best method as there may be deficiencies in the existing

program.

This will require some planning with people or plans that show the same output

functions as discussed above – notification appliances, messages or codes,

relays, monitoring and anything else specific to this site.

Once the entire system operation has been recorded or developed new, the

programming of new object labels and rules can be done to create the desired

operation. The experience and skill of the programmer will greatly affect how efficient

the new project file will be. In most cases the object labels and rules can be very

effective at producing the desired functionality.

Caution: Before downloading, The AHJ should be consulted if they haven’t already

been part of this process up to this point. Once downloaded, the system will have a

new project database and the entire system must be 100% tested to verify that the new

database was properly configured. If the AHJ wants to witness the testing the same asa new installation, code requires that a 100% pre-test be conducted.
