2GIG Wireless Carbon Monoxide Alarm

Why Choose This with Smart Shield Systems

• We match the right model: CO8e-345 for eSeries (encrypted) panels, CO8-345 for classic 345-MHz 2GIG panels, or CO3-345 where appropriate—we confirm panel compatibility first.

• Correct programming: added as a 24-hour Carbon Monoxide zone and tested so central station signals and app alerts work exactly as intended.

• Code-aware placement: installed near sleeping areas and fuel-burning appliances, following manufacturer guidance for distance from kitchens, vents, and drafts.

• Lifecycle care: we document the detector’s end-of-life date and schedule checkups so you’re never unprotected.

Key Features

• Electrochemical CO sensing with wireless reporting of alarm, tamper, supervision, and low battery to your panel.

• Loud local alert: ≥85 dB T4 pattern sounder for CO events.

• Long life design: 10-year sensor & projected battery life on CO8/CO8e; legacy CO3 provides 5-year sensor life.

• Strong RF performance: up to ~350 ft open-air range (site-dependent).

• Listed & compliant: UL 2075 and related listings on the CO8/CO8e line.

• Encrypted option: CO8e-345 uses AES-128 encryption for secure signaling to eSeries panels.

Compatibility Notes

• Panels: CO8e-345 → GC2e / GC3e / EDGE; CO8-345 → 2GIG 345-MHz panels; CO3-345 → legacy 2GIG 345-MHz systems. We verify panel firmware and radio before install.

• Monitoring & apps: when paired to your 2GIG system, Alarm.com can deliver push/text alerts and dispatch through your monitoring plan. (Behavior depends on your account configuration.)

Popular Use Cases

• Hallways outside bedrooms and inside sleeping areas

• Near fuel-burning appliances (furnace rooms, attached garage doorways—placed per manufacturer guidance)

Frequently Asked Questions

Where should a CO detector be installed?

Follow the manual’s guidance: near sleeping areas and on each level; avoid locations directly over stoves/sinks, within 5 ft of cooking appliances, next to drafts/vents, or where dust can accumulate. Wall-mount at least switch-height; ceiling-mount ≥12″ from walls. We handle placement for you.

How is it programmed on the panel?

We enroll it as a 24-hour Carbon Monoxide zone type so it reports day or night, armed or disarmed.

What’s the alarm pattern and volume?

CO events sound Temporal-4 (four short beeps) at about 85 dB and send an alarm to the panel/monitoring center.

How long does it last?

CO8/CO8e list 10-year sensor life (with projected 10-year batteries); the older CO3 is 5-year. The detector will chirp/indicate end-of-life when it’s time to replace.

Does the encrypted model work with any 2GIG panel?

Use CO8e-345 with GC2e/GC3e/EDGE (encrypted). For classic 345-MHz panels without eSeries, use CO8-345 (non-encrypted)
