Job Overview

This project qualifies you to inventory, test, and service every accessible smoke alarm, carbon-monoxide alarm, and combination alarm in one residence, and to visually inspect approved emergency equipment and exit routes. The finished work product is a single dated device-by-device test record identifying manufacturer, model, power source, interconnection, test result, battery service, deficiencies, and replacement actions, supported by a walked and documented exit-route review.

You will notify occupants and any monitoring service before testing, locate and record every accessible alarm and emergency device, test each alarm using its built-in test control and manufacturer procedure, replace only the specified battery type where applicable, visually inspect fire extinguishers and escape equipment without discharging or deploying them, walk primary and secondary exit routes, and restore monitoring status before closing out the project.

This project builds directly on the Chapter 1 baseline walkthrough and the Chapter 12 electrical device review, both of which located alarms, exits, and panel information without testing them. It feeds directly into Chapter 18, which repeats alarm testing on a seasonal cycle, and into Chapter 19 and Chapter 20, where any failed alarm or blocked exit becomes an immediate-hazard item in the property's prioritized plan.

Skills You Will Demonstrate

  • MI-073 — Test smoke alarms using their built-in test controls and manufacturer procedures.
  • MI-074 — Test carbon-monoxide alarms using their built-in test controls and manufacturer procedures.
  • MI-075 — Replace alarm batteries with the specified battery type, orientation, and date-marking procedure.
  • MI-076 — Inspect fire extinguishers visually for accessibility, damage, pressure indication, and service status.
  • MI-077 — Check emergency exit routes for obstruction and safe operation.
  • MI-078 — Document a complete life-safety readiness record with device inventory, test results, and replacement needs.

Where This Skill Fits

Chapter 1 located alarms, exits, and emergency equipment as part of the baseline walkthrough, and Chapter 12 inspected accessible electrical devices without testing life-safety equipment. This project completes the life-safety picture by testing every device on record and confirming exit routes are usable, without opening any panel, dismantling any alarm, or performing electrical repair.

The device inventory and test record produced here become the life-safety section of the Chapter 2 property binder, are repeated on the seasonal cycle in Chapter 18, and are escalated directly into the Chapter 19 30-60-90 day plan whenever a device fails, is beyond its documented service life, or an exit route is found blocked. The Chapter 20 capstone repeats this exact test-and-document procedure at full property scale.

Scope and Intended Use

This project covers:

  • notifying occupants and any monitoring service before testing interconnected or monitored devices
  • inventorying every accessible smoke alarm, carbon-monoxide alarm, combination alarm, hearing-impaired alert device, fire extinguisher, escape ladder, emergency light, and designated exit
  • testing each alarm using its built-in test control and manufacturer procedure only
  • replacing removable batteries only with the manufacturer-specified type, orientation, and date-marking procedure
  • visually inspecting fire extinguishers and approved emergency escape equipment without discharging, deploying, or servicing them
  • walking primary and secondary exit routes and identifying obstructions
  • producing one device-by-device life-safety readiness record

This project does not authorize the learner to:

  • use flame, candles, matches, smoke, vehicle exhaust, canned gas not approved for the device, or any other improvised test source
  • remove, silence, relocate, paint, cover, or disconnect a required alarm without an approved replacement and authorization
  • discharge a fire extinguisher as a routine test, or service, recharge, or repair a fire extinguisher, alarm, or escape device
  • service devices connected to a managed security, fire, sprinkler, or elevator system except through the approved authorized-service procedure

Any alarm that fails, chirps, shows a fault, is beyond its documented service life, lacks required power, or cannot be safely accessed must be identified for prompt replacement rather than reset and left in place. Any blocked or unsafe exit route must be reported to the responsible party before the walkthrough continues.

Reference Conventions

Establish these references before testing begins, and do not change them mid-project.

Prerequisites

Common Field Fundamentals

Life-safety testing in this book follows the same discipline established in Chapter 1: confirm scope, observe and test, document, separate hazard from routine, and record limitations. Here that discipline is applied specifically to devices whose entire purpose is to alert occupants to fire, carbon monoxide, and blocked escape, so a missed or mishandled test carries more consequence than a missed cosmetic finding elsewhere in the property.

Device inventoryLocate and label every accessible smoke alarm, CO alarm, combination alarm, extinguisher, and escape device
Alarm testingBuilt-in test control only, one device at a time, with interconnection verified per the approved procedure
Battery and fault serviceManufacturer-specified batteries only; failed or end-of-life devices flagged for replacement, not reset
Emergency equipmentVisual inspection of extinguishers and escape equipment without discharge or deployment
Exit routesPrimary and secondary routes walked from sleeping and occupied areas
CloseoutMonitoring status restored and readiness record filed before leaving the property

Testing Versus Servicing

This project tests and performs only the battery service described in the outline. It does not authorize disassembly, recalibration, sensor cleaning beyond the manufacturer's basic user-level instruction, or any repair of an alarm, extinguisher, or escape device. A device that fails its built-in test, shows a fault, or is beyond its documented service life is a replacement item, not a repair item, within this chapter's scope.

E. Preparation — Notification, Inventory, and Setup

  1. Review property and device background. Review adopted requirements, property type, sleeping areas, fuel-burning equipment, attached-garage conditions, prior alarm records, and manufacturer instructions.
  2. Notify occupants and the monitoring service. Notify occupants and monitoring services as required before testing interconnected or monitored devices, and record the notification on the worksheet.
  3. Identify every device and exit. Locate every accessible smoke alarm, carbon-monoxide alarm, combination alarm, hearing-impaired alert device, fire extinguisher, escape ladder, emergency light, and designated exit.
  4. Record device identity from each label. Record manufacturer, model, power source, interconnection, location, manufacture date, replacement date if known, and visible condition for each device.
  5. Confirm no device will be altered without authorization. Do not remove, silence, relocate, paint, cover, or disconnect a required device without an approved replacement and authorization.

F. Pre-Test Visual Inspection

  1. Inspect each alarm before testing. Check for damage, obstruction, paint, contamination, loose mounting, a missing battery door, a removed battery, and end-of-life indication.
  2. Verify device type and location against available information. Compare the device and its location to product instructions and adopted requirements without representing the review as a code certification.

G. Alarm Testing

  1. Test using the built-in control only. Use the built-in test control and manufacturer procedure for each alarm.
  2. Do not use an improvised test source. Do not use flame, candles, matches, smoke, vehicle exhaust, canned gas not approved for the device, or any other improvised test source.
  3. Confirm output at the device. Confirm audible and visible output at the device being tested.
  4. Confirm interconnection through the approved procedure. Confirm interconnected activation only through the approved system procedure, coordinated with occupants.
  5. Verify audibility where included in scope. Verify occupants can hear or receive the required notification in sleeping and occupied areas where the project scope includes this assessment.
  6. Stop for managed systems. Stop and refer alarms connected to security, fire, sprinkler, elevator, or other managed systems when testing requires authorized service outside this project's scope.

H. Battery Service and Retesting

  1. Replace only the specified battery. Replace removable batteries only with the specified battery type, orientation, and date-marking procedure.
  2. Do not substitute a battery for required replacement. Do not install a battery in a damaged, contaminated, recalled, or end-of-life alarm as a substitute for replacing the device.
  3. Restore the device after service. Restore battery doors, mounting, power, and interconnection after service.
  4. Retest after service. Retest every alarm after battery replacement or remounting.
  5. Flag devices requiring replacement. Identify alarms that fail, chirp, show a fault, are beyond documented service life, lack required power, or cannot be accessed safely, and arrange prompt replacement with compatible approved equipment.

I. Emergency Equipment and Exit-Route Inspection

  1. Inspect fire extinguishers visually. Check accessibility, correct location, visible damage, corrosion, leakage, broken seal, missing pin, hose condition, pressure indication where present, service tag, and labeling.
  2. Do not discharge or service an extinguisher. Do not discharge an extinguisher as a routine test, and refer damaged, discharged, recalled, improperly rated, unserviceable, or questionable extinguishers for approved service or replacement.
  3. Inspect escape ladders and other approved equipment without deploying them. Check access, packaging, instructions, compatibility, and expiration or service information.
  4. Walk primary and secondary exit routes. Walk routes from every sleeping and occupied area.
  5. Verify exit operation. Confirm doors, windows, halls, stairs, landings, locks, and exterior paths are not blocked and can be operated as required.
  6. Identify obstructions. Note security devices, bars, storage, furniture, damaged hardware, snow, or landscaping that may obstruct emergency escape.
  7. Inspect supporting emergency information. Check posted emergency contacts, flashlights, first-aid supplies, and utility-shutoff information where included in the property plan.

J. Closeout and Recordkeeping

  1. Restore monitoring status. Restore monitoring status and notify occupants and the monitoring service that testing is complete.
  2. Complete the device-by-device test record. Record date, test method, result, battery, age information, deficiencies, replacement action, and next required condition for every device.
  3. Update the property log. File the readiness record in the property binder and issue immediate action for any failed required alarm or blocked exit.

Project Closeout

You have completed the thirteenth project in the property maintenance and building inspection sequence: testing smoke alarms, carbon-monoxide alarms, and emergency equipment. This project required you to test smoke alarms using built-in controls (MI-073), test carbon-monoxide alarms using built-in controls (MI-074), replace batteries with the specified type and procedure (MI-075), inspect fire extinguishers visually (MI-076), check emergency exits for obstruction (MI-077), and document a complete life-safety readiness record (MI-078).

You now have a dated, device-by-device record of this property's life-safety readiness, with every alarm tested, every failed or aging device flagged for replacement, and every exit route confirmed usable. This record feeds directly into the seasonal interior maintenance cycle and the prioritized repair plan later in this book.

File your completed life-safety readiness record and photographs where they can be retrieved for Chapter 18 and Chapter 19. You will repeat this exact test-and-document procedure on the seasonal cycle and again at full property scale in the Chapter 20 capstone.
