Summary
The CO-200 is a new stand-alone carbon monoxide detector from Zeta Alarm Systems. Designed to fit the dimensions of a standard 2-gang fitting, it offers flexible installation options, either surface-mounted with its own backbox or semi-flush with a standard recessed box. This versatility ensures it can be seamlessly integrated into various environments.

Power options for the CO-200 include a 230V AC mains supply or a DC supply ranging from 9 to 28V. It features a built-in bar graph display to indicate the current CO level, and a 2-stage relay output that activates at the first alarm level of 100ppm and the second alarm level of 200ppm. Additionally, it provides a 5-volt alarm output capable of supplying 200mA.
The device is equipped with power, fault, and alarm indicators, alongside a control button for muting (press) and resetting (press and hold for 5 seconds). This comprehensive feature set ensures reliable and user-friendly operation.
Features
- Dual power option – runs from 230V AC mains or a 9-28V DC supply, so you can fit it on mains-only jobs or tie it into an existing low-voltage system
- Standard 2-gang footprint – matches a typical 2-gang fitting, letting you surface mount with the supplied backbox or semi-flush it into a standard recessed box for a neater finish
- On-board bar graph display – gives a live CO ppm reading at a glance, useful for diagnosing nuisance alarms or verifying performance on service visits
- 2-stage relay output – switches at first alarm level (100ppm) and second alarm level (200ppm), so you can stage interlocks such as ventilation or shutdown circuits
- 5V auxiliary alarm output – delivers up to 200mA to drive external sounders, beacons or interface modules without extra power supplies
- Mute and reset control – single press silences the alarm, press and hold for 5 seconds resets the unit, keeping site call-outs simple for the end user
- 85dB buzzer at 3m – built-in sounder gives a clear local warning without needing a separate audible device
- Fast response sensitivity – detects 300ppm within 3 minutes, 100ppm within 30 minutes and 50ppm within 90 minutes, and responds in under 30 seconds to a step change
- Power, fault and alarm indicators – clear status LEDs let you confirm correct operation during commissioning and routine checks
FAQ
The CO200 provides two relay outputs (first alarm at 100ppm and second alarm at 200ppm) plus a separate 5V/200mA alarm output, so it can be used to trigger external equipment such as a sounder, panel input or shutdown relay. Confirm the exact contact ratings and wiring configuration in the full installation manual before connecting to a third-party panel, as this isn’t detailed on the datasheet. Yes to both. The CO200 is sized to match a standard 2 gang fitting, so it can be surface mounted using its own backbox, or fitted semi-flush onto a standard recessed box if you’d rather keep the profile low on the wall. The unit will run from 230V AC mains or from a 9-28V DC supply, giving you flexibility on sites where running a mains spur isn’t practical. Quiescent draw is 20mA, rising to 40mA on start-up and up to 300mA in alarm (excluding the alarm output), so size any DC supply or battery backup accordingly. A single press of the control button mutes the buzzer, which is useful for quieting a nuisance alarm without walking away from the fault. Pressing and holding the same button for 5 seconds performs a full reset, so there’s no need for a separate reset switch or tool. Response time is under 30 seconds, with sensitivity rated at 50ppm within 90 minutes, 100ppm within 30 minutes, and 300ppm within 3 minutes. These figures give you a reference point for explaining detection behaviour to a client, but check the manufacturer’s documentation if you need confirmation against a specific installation standard. It’s rated for operating temperatures of 0°C to 50°C and up to 95% RH (non-condensing), which covers most garages, plant rooms and similar semi-conditioned spaces. Avoid locations that could fall outside that temperature or humidity range, as the datasheet doesn’t specify performance beyond these limits.Can the CO200 be wired into a fire alarm panel or other monitoring system?
