Instructions - Power Fail Alarm (PFA-2)

1. OPERATION MODES• When there is a power failure, the buzzer sounds red LED blinks. The green button silences the buzzer. The red LED continues to blink as until the fault is corrected. If enabled, a “snooze alarm” feature causes the buzzer to sound again 30 minutes after being silenced.• The “Plug Detection” feature causes an alarm if your plug is pulled out of the receptacle in the PFA-1. Your plug is detected using the ground prong.• The unit can produce an immediate alarm to detect millisecond power interruptions, or alternatively, the unit can delay before sounding. The immediate alarm is also latching so short interruptions will not be missed.2. SELECT MODEThe jumper pins determine the different modes as in the tables.Jumpers C and D work in combination to produce 4 different modes as follows:3. INSTALLA contact closure or 9V output is available on terminals marked JP3. See above “C and D” table for the various durations.CONTACT CLOSE (DEFAULT):Remove jumper. Terminals O+ and O- will close for 5 seconds when there is an alarm condition. The O+ terminal is positive. 5 sec. output repeats every 30 mins until button pushed. 9V OUTPUT A jumper across 0- and - gives a 5 second output across O+ and + terminals. The + terminal is positive. 5 sec. output repeats every 30 mins until button pushed.4. OTHER NOTES• LED FLASHING: always indicates a fault, either no power, or low battery, or no plug. (if plug detection is enabled. • PLUG DETECTION: there can be up to a 15 second delay before a missing plug is detected.• BATTERY LIFE is more than 10 years if passively monitoring. Extended use of the buzzer (70 hours) or flashlight will naturally deplete the battery. Low battery voltage is signaled by 5 seconds of quick beeping twice per minute and continuous flashing of the red LED.Feb 4, 2013POWER FAIL ALARM (PFA-2)Engineering 205 Seneca Parkway, Rochester, NY 585-301-0970 www.drumalarm.comGizmoC D MODE BUZZER DELAY LATCHING CONTACT CLOSE (J5)ON ON 1 None Yes. ?
