Smoke & CO Detector Types for Seguin Homes

Not all detectors are equal. Here’s exactly which types Moorhead installs and what each protects against.
Smoke Protection
Hardwired Smoke Detector
Powered by your home’s electrical system with a battery backup. If the power goes out during a fire, the backup battery keeps it running. Hardwired units throughout your home interconnect so when one sounds, all sound.
  • Hardwired 120V with battery backup
  • Interconnected β€” all alarm simultaneously
  • Ionization (fast fires) or Photoelectric (slow fires)
  • Required by Texas code in new construction
  • Replace every 10 years per NFPA
⭐ Best Value β€” Dual Protection
Combination Smoke + CO Detector
One hardwired unit protects against both fire smoke AND carbon monoxide β€” the most common choice for Seguin homes with gas appliances. Reduces the number of units needed while ensuring full coverage of both hazards.
  • Smoke AND carbon monoxide detection in one unit
  • Hardwired with battery backup
  • Interconnected with all other alarms
  • Distinct alarm tones for smoke vs. CO
  • Ideal for bedrooms near gas appliances
  • Smart versions connect to app (Nest Protect)
CO Protection
Carbon Monoxide Detector
CO is colorless, odorless, and completely undetectable without a sensor. Every Seguin home with a gas furnace, gas water heater, gas range, attached garage, or standby generator needs CO detectors near all sleeping areas.
  • Detects invisible, odorless CO gas
  • Hardwired near sleeping areas
  • Electrochemical sensor β€” most accurate type
  • Replace every 5–7 years (shorter life than smoke)
  • Required in any home with gas appliances in TX
  • Critical with Generac generators

Which Smoke Detector Technology Is Right For You?

Ionization vs. Photoelectric

Ionization ⚑

Best For: Fast, Flaming Fires

Contains a tiny amount of radioactive material that ionizes air between two plates. Faster at detecting rapidly spreading, flaming fires β€” like a kitchen grease fire or curtain fire. More prone to false alarms from cooking smoke.

Best placed: Kitchen area, living room, garage

Photoelectric πŸ’‘

Best For: Slow, Smoldering Fires

Uses a light beam to detect smoke particles. Better at detecting slow, smoldering fires β€” which are most common in bedrooms (overheated electrical, smoldering furniture). Less prone to cooking false alarms. USFA recommends this type for bedrooms.

Best placed: All bedrooms, hallways, sleeping areas
The USFA recommendation for Seguin homeowners:Β InstallΒ both typesΒ β€” or useΒ dual-sensor combination unitsΒ that include both technologies in one detector. This provides the fastest detection for any type of fire in any room. Moorhead recommends and installs dual-sensor units as our standard for Seguin homes.
Why CO Detectors Are Critical in Seguin ο»Ώ

Every CO Source in Your Seguin Home

Carbon monoxide is the silent killer β€” colorless, odorless, and impossible to detect without a sensor. South Texas homes have more CO sources than most people realize. Moorhead is the only contractor in Seguin who handles three of them.
Generac Standby Generator
Produces CO during every operation β€” including routine weekly self-tests that happen while you’re asleep. Wind patterns can carry CO through vents, windows, and attic spaces into living areas.

⚠️ High Risk β€” Moorhead Installs Both

Gas Furnace & HVAC System
A cracked heat exchanger β€” the most common furnace failure β€” silently leaks CO into your air supply. Annual HVAC service catches this. Moorhead handles both HVAC service and CO detector installation.
⚠️ High Risk β€” Moorhead Handles Both
Gas Water Heater
Improperly vented or aging gas water heaters produce CO that can accumulate in utility rooms, closets, and connected living spaces. A CO detector in or near the utility area is essential.
⚠️ Common in Seguin Homes
Attached Garage & Vehicles
Running a vehicle in an attached garage β€” even briefly β€” produces dangerous CO levels. CO seeps through door gaps, vents, and shared walls. CO detectors near the garage-house door are critical.
⚠️ Very Common in Seguin
Gas Range & Cooktop
Older gas ranges or misused burners can produce CO, especially in poorly ventilated kitchens. A combination smoke/CO detector near the kitchen (not in the kitchen) provides protection without false alarms.
⚠️ Common Risk
Fireplace & Wood-Burning Stove
Blocked flues, improperly vented fireplaces, and wood-burning stoves can backdraft CO into living spaces. South Texas winters mean these are used seasonally β€” making annual CO detector checks critical.
⚠️ Seasonal Risk
Texas Law & Code Requirements

What Texas Law Requires in Seguin

No competitor in Seguin cites this β€” but Texas law is specific about what your home must have. Most older Seguin homes don’t comply with current code.

Texas Law & Code Requirements

What the Law Requires

Texas law requires landlords to install smoke detectors inΒ each bedroom,Β outside each sleeping area, andΒ on each level of the home. New construction and renovations must comply with the International Residential Code (IRC), which requiresΒ hardwired, interconnected detectors with battery backup. Homes being sold in Seguin must have working detectors in all required locations to pass inspection.

Home Sale Preparation

Selling Your Seguin Home?

Smoke and CO detectors are one of the first things home inspectors check in Guadalupe County. Missing, expired, battery-only (where hardwired is required), or improperly placed detectors can flag your inspection report and delay your closing.
01
Pre-Listing Detector Audit
We assess your current detectors, identify any that are expired, missing, or improperly placed, and give you a flat-rate quote to bring everything up to code before your listing photos are taken.

02

Pass Inspection the First Time
Moorhead Service Company provides written documentation of all detector installation including model, location, manufacture date, and compliance standard β€” exactly what your inspector and buyer need to see.

03

One Less Thing for Closing
A licensed contractor installation with permit (if required) and documentation protects you as a seller. We provide a complete installation record for your closing file.
Code-Compliant Placement

Where to Place Smoke & CO Detectors in Your Seguin Home

Placement matters as much as having detectors at all. Moorhead uses NFPA 72 and Texas code standards for every installation.
πŸ›οΈ Each Bedroom
Smoke: Inside every bedroom β€” on ceiling or high on wall
CO: Combination unit or dedicated CO detector near sleeping areas
Texas law and NFPA 72 require smoke detectors inside every bedroom. CO detectors are required near sleeping areas where gas appliances are present. We recommend combination units in every bedroom.
⚠️ Required by Texas Law
πŸšͺ Hallways Outside Bedrooms
Smoke: Ceiling center of hallway or top of wall
CO: Combined unit if multiple bedrooms share one hallway
A single hallway detector can cover multiple bedrooms if placed centrally and interconnected. Must be within 15 feet of every sleeping area it’s intended to protect.

⚠️ Required by Texas Law

🍳 Kitchen Area
Smoke: Ceiling at least 10 feet from the stove to reduce false alarms
CO: Combination unit near entry to kitchen, not above stove
Never mount a smoke detector directly above the stove β€” cooking will trigger constant false alarms. The 10-foot rule minimizes false alerts while maintaining early detection of actual kitchen fires.
βœ“ Strongly Recommended
πŸš— Garage Entry Door
Smoke: Inside garage near door to living space
CO: Inside living space next to garage entry door
The attached garage is one of Seguin’s highest CO risk locations β€” vehicle exhaust enters the home through door gaps and shared walls. A CO detector just inside the door to the house is critical.
⚠️ Required β€” Any Attached Garage
βš™οΈ Utility Room / Furnace Area
Smoke: Near water heater and furnace area
CO: Within 10 feet of gas water heater and furnace
Gas furnaces and water heaters are the most common source of CO in Seguin homes. A dedicated CO detector in or adjacent to the utility room provides the earliest possible warning of a furnace or water heater CO leak.
⚠️ Required β€” Gas Appliances
πŸ“Ά Every Level of the Home
Smoke: At least one detector on each floor level
CO: At least one CO detector on each level near sleeping areas
Texas code and NFPA 72 require detection coverage on every level β€” including basements. In multi-story Seguin homes, we install interconnected detectors so a fire anywhere sounds everywhere.
⚠️ Required by Texas Law
When to Replace

Detector Replacement Timeline

Detectors expire. Most Seguin homeowners don’t know their detectors’ age. We check the manufacture date on every unit during our free assessment.
5–7

Years Max Life

Carbon Monoxide Detectors
CO detectors degrade faster than smoke detectors. The electrochemical sensor inside expires in 5–7 years β€” even if the unit still appears to function. If your CO detectors are older than 2018, they likely need replacement now.
10

Years Max Life

Smoke Detectors
The NFPA recommends replacing all smoke alarms 10 years from the manufacture date stamped on the back of the unit. If your home was built before 2015 and detectors haven’t been replaced, they’re likely expired. We check every unit.

1

Year β€” Battery Check
Battery Backup Test & Replace
Hardwired detectors with battery backup should have their batteries tested monthly and replaced annually. We recommend the “spring forward, fall back” trick β€” replace batteries every time daylight saving changes. Moorhead tests all batteries during installation and annual HVAC service visits.

Common Questions

Smoke & CO Detector FAQS for Seguin Homeowners

Are hardwired smoke detectors required by Texas law in Seguin?

Yes. Texas Property Code Section 92.255 requires smoke detectors inside each bedroom, outside sleeping areas, and on each level of the home. New construction and renovations in Seguin must comply with NFPA 72, which requires hardwired interconnected detectors with battery backup. Many older Seguin homes are not in compliance.

How often should smoke and CO detectors be replaced in Seguin?
Smoke detectors should be replaced every 10 years from the manufacture date stamped on the back. CO detectors need replacement every 5–7 years β€” their electrochemical sensor degrades faster. We check the manufacture date on every unit during your free assessment and replace only what needs it.
Why do I need CO detectors if I have a Generac generator?
Generac generators produce carbon monoxide during every operation β€” including the automatic weekly self-test that runs while you’re asleep. Even properly vented outdoor generators can allow CO to enter your home. As the installer of your generator and your HVAC system, Moorhead knows your exact CO risk and places detectors accordingly.
What's the difference between ionization and photoelectric smoke detectors?
Ionization detectors respond faster to fast, flaming fires. Photoelectric detectors respond faster to slow, smoldering fires β€” which are more common in bedrooms. The USFA recommends both types, or dual-sensor combination units. Moorhead installs dual-sensor units as our standard recommendation for Seguin homes.
Do smoke detectors affect my home sale inspection in Seguin?
Yes significantly. Home inspectors in Guadalupe County verify detector placement, function, and age. Missing, expired, or battery-only detectors where hardwired are required can flag your inspection report. Moorhead offers pre-sale detector audits and provides written compliance documentation for your closing file.
Can you upgrade my battery detectors to hardwired?
Yes. We run wiring from existing detector locations or your panel to upgrade battery detectors to hardwired interconnected units. In most Seguin homes built after 1980, the existing wiring is partially in place and the upgrade is straightforward. We assess your current wiring during the free on-site visit.
Do you install smart smoke detectors like Nest Protect in Seguin?
Yes. We install Google Nest Protect and First Alert Onelink WiFi detectors β€” hardwired with battery backup, app-connected, and voice-enabled. Smart detectors send phone alerts when you’re away, tell you exactly which room has smoke or CO, and test themselves automatically. No other Seguin electrician currently installs or supports these.
The Seguin Fire Department offers free smoke detectors β€” is that enough?
The Seguin Fire Department’s free program provides battery-operated detectors to those who cannot afford them β€” and it’s a valuable community resource. However, battery-only detectors are not compliant with current Texas code for hardwired homes, and they don’t interconnect. For code compliance, home sales, and maximum protection, professionally hardwired interconnected detectors are the proper standard.

“Moorhead replaced all our old battery detectors with a hardwired interconnected system throughout the house. Now if one goes off, they all go off. They placed them exactly where code requires and tested every unit before leaving. That’s the kind of peace of mind you can’t put a price on.”
Patricia H.

Seguin, TX

“We bought a 1980s home in Seguin with no CO detectors β€” and we have a gas furnace, gas water heater, and a Generac generator. Moorhead came out, assessed the whole house, and installed hardwired CO detectors in every critical location. They even checked that our generator was properly vented. Very thorough.”
Robert G.

Seguin, TX β€” Lake Placid

“Had them install combination smoke/CO detectors before listing our house. Our realtor said it’s the first thing inspectors check in Seguin. Moorhead did every bedroom, every level, passed inspection first try. Fast, clean, flat-rate. Life really is better with Moorhead.”
