[1] This device was tested to the Regulated 24 DC/FWR operating
voltage limits of 16 V and 33 V. Do not apply 80% and 110% of these
values for system operation.
[2] When this device is used as a low frequency sounder in sleeping
quarters, the strobe's candela switch (Figure 1) must be set to 110 cd.
