l Temperature Sensor
If temperature drops below 45°F the Monitors alarm chirps (Item s) and Power Light blinks (Item k). The UltraGuard signals
the alarm panel (if connected), which will notify the monitoring station of the condition. When the temperature rises above 45°F
the UltraGuard will return to normal operation and the Power Light will return to the steady on condition.

Blinking (alarm chirps Item s) Indicates that the UltraGuard internal clock has determined that the CO Detector(s) need
to be replaced in order to provide continuing protection. The Alarm may be silenced by pushing the Reset button (Item j). The
light will remain ON until the CO Detectors are replaced and the system is reset. Promptly replace the CO Detectors! (See
Replacement Instructions on the Page ).
nopq Zone Alarm Lights (Red)
Light Off Normal Condition
Blinking (alarm Item s is ON and Trouble Light item r is OFF) Indicates that the CO Detector(s) in that zone is
(are) detecting DANGEROUS LEVELS OF CARBON MONOXIDE.
LEAVE THE AREA AT ONCE!
When CO dissipates the zone light will go from blinking to a steady on condition indicating that an alarm condition has
occurred.
Note: An alarm condition that occurs and then clears itself will cause the zone light to stay on (steady). Furnace operation will
only be interrupted while the alarm condition exists. Determine the cause of the alarm! Press and hold the RESET button (Item
j) until the zone light turns off.
r Trouble Light (Yellow)
Light Off Normal Condition

CO Detector is faulty and should be repaired or replaced OR any one of the 5 faults shown on page 2 exists and must be corrected.
NOTE: the alarm may be silenced by pushing the Reset button (item j).
If the trouble condition clears itself, the alarm will stop chirping but the trouble light will stay on and the Zone light will continue
to flash, indicating the Zone that caused the Trouble light to be on. For your continued protection, the cause of the Trouble light
should be determined.
s Audio Alarm. A chirping sound is triggered when dangerous or fault conditions occur (see items j r for details).
