Battery types:
2 each 1.5 volt alkaline type ‘AA’
DURACELL ULTRA alkaline batteries or equivalent.
Battery Life:
100 Hrs. @ ~25° C. @ ~25% R.H. Measured from
mean, assuming fresh DURACELL ULTRA alkaline batteries operating under normal operating conditions.
NOTE: Make sure alkaline batteries are used and removed during long-term storage.
Nominal battery voltage:
~2.875 VDC ± 40 mv.@ 2.25 ma. Idle. 100 ma. Peak (~50 ms. max), 3.25 ma. Average.
Min. start-up voltage:
~2.5 VDC ± 40 mv.
Low-battery cut-out:
< 2.0 VDC ± 40 mv. (Red light on steady unit in non-responsive state ‘dead’)
Very low battery signal:
~2.25 VDC ± 40 mv. (Red light winking 2/sec.) ~5 Hrs. of service left.
Low battery signal:
~2.4 VDC ± 40 mv. (Red light winking 1/sec.) ~12 Hrs. of service left.
Notes:
The low battery cut-out feature provides a known state of action if the batteries are depleted to the point of inadequate power to operate
the unit to any of the declared specifications. In addition, this feature was found to be prudent because, while many of the specifications may
stay intact, false triggering of the valve may confuse the operator of a problem other than low batteries. The minimum ‘start-up’ voltage is
where the unit will initiate the built-in test and commence operations. However, it should be noted that, during this operation, if the batteries
are then measured to be too low the lock-up feature may then shortly ensue. This should help the operator in determining if the unit is bad or
if the batteries are too low. A unit that has low batteries that cause ‘lock-up’ will most likely initially start-up if left off for some time. Alkaline
type batteries have so-called self-rejuvenating properties that may cause the user to stall battery replacement. Obviously, dead batteries will
yield no action.
The O2D1 Specifications, performance standards and limits are derived from actual units tested,
characterized or calculated. Specifications are subject to change without notice.
