Activating and restoring gas accelerated response
Use the Activate Gas Accelerated Response option to turn on the accelerated response mode.
Under normal conditions, it takes approximately four minutes at 400 PPM of CO before a CO
detector activates. This mimics the normal absorption rate of CO in the bloodstream. When
testing a CO device, you can put the CO detectors in the CO accelerated response mode,
which shortens the time to activation to be between four to eight seconds at 400 PPM of CO.
You can activate a gas accelerated response on devices that have a CO sensor. See Table 11
on page 47. Once activated, the gas accelerated response on that device remains active for
four hours, unless you manually restore it, or the device returns from a communication fault.
To activate/restore gas accelerated response:
1. Press the Menu button and choose Control.
2. Enter a level one password.
3. Choose Activate/Restore.
4. Choose Gas Accel Response.
5. Select the device that you want to accelerate.
6. Press Enter.
7. Press Cancel to return to the previous menu.
