zero to eight minutes (field adjustable in on minute increments) per hour.
This timed fan run shall be different from the minimum run time setting. A
switch shall be provided to enable to disable the time base operation
c. The CO controller shall be designed such that in the event of a power
failure the control unit shall set itself to an alarm condition and upon
power restoration shall automatically activate the fan output to clear any
possible accumulated toxic gases.
d. The controller shall have an LED to indicate alarm condition of the
remote sensor.
e. Options available for CO System Controllers:
1. Power "ON" light emitting diode (LED) to indicate power to system
2. Fan ON (LED) indication
3. Local alarm horn and/or light. Horn has silence switch.
4. Remote alarm panel.
5. Calibration Kit.
6. Keyed panel lock(s.)
B. Design Requirements:
1. Provide clearly labeled light emitting diodes (LED’s) indicating lamps on the face
of the controller panel to indicate the following:
a. Power "ON" to system -- Green LED.
b. One Red LED to indicate high CO condition (warning level).
c. One Red LED to indicate Alarm condition.
2. Provide an audible alarm with a minimum sound intensity of 68dB, on the face of
the control panel. Provide an "Audible Silence" push button switch to silence the
