INTRODUCTION:
NFPA 1901, Standard for Automotive Fire Apparatus, 1996 Edition, paragraph 9.3.3 requires a
low voltage alarm to detect whenever the battery voltage of a vehicle drops below a threshold for
a 2 minute interval.The Model 091-85-XX, LowVoltage Alarm/1901 is a voltage sensing device
which is designed to fulfill the requirements of referenced NFPA 1901 Standard.
The Model 091-85-XX contains voltage sensing circuits, a 2 minute timer, an output relay as well
as RED and GREEN colored LEDs to indicate status.
Inoperation the Model 091-85-XXcontinuallymonitors asystem voltagepresentat J1-1(+VDC)
with respect to J1-2 ( VDC Return). When the system voltage is equal to or greater than the
following “Low Voltage Thresholds” the GREEN LED is illuminated indicating a normal system
voltage.
ModelType NominalSystemVoltage LowVoltageThreshold
091-85-12 12.0VDC 11.8VDC
091-85-24 24.0VDC 23.6VDC
091-85-24-VER 24.0VDC 23.0VDC
Whenever the monitored system voltage drops below the ModelType “LowVoltage Threshold” a
timer internal to the Model 091-85-XX is started.If the LowVoltage condition continues for more
than2 minutesthe Model 091-85-XX outputRELAYisenergized,theGREEN LED will extinguish
and the RED LED will illuminate.The output RELAY will remain energized (COM makes NO) until
the sensed system voltage rises above;
12.8VDC for Model091-82-12
25.6VDC for Model091-85-24
24.8VDCfor Model 091-85-24-VER
The output relay has both normally open (NO) and normally closed (NC) contacts available
providingtheinstaller withcompleteflexibilityinwiring thealarmcircuit.Anyexternalalarmindicator
or alarm horn must be provided by the installer consistent with the output relay contact ratings
provided in Model specifications.The Model 091-85-XX is NOT waterproof so it is suggested that
it be mounted in a suitable location. Care should be taken to wire the +VDC AND VDC Return
sense lines to an electrical point representative of system voltage monitoring requirements so
thatanaccurateindicationof system voltagemaybe obtained.Fuse+VDCsenselineas required
using ONLY an ultra low resistance/voltage drop device.
Refer to Figure 1 for illustration of a typical wiring configuration and output relay contact rating(s).
