General Notes:
•
Wheelock UL 1638 Strobes are designed to produce 30-62 fl ashes per minute over the Regulated Voltage Range. If used in an indoor application,
UL 1638 strobes must be operated at a minimum of 20 VDC to meet the NFPA-72 (1999) fl ash rate of 1 to 2 fl ashes pers second and ADA Guideline
fl ash rate of 1 to 3 fl ashes per second.
•
Wheelock Weatherproof Appliances are designed to operate over an extended temperature range of -31
ratings represent minimum effective strobe intensity based on UL 1638. Maximum humidity of 93% RH ± 2%.
•
"Regulated Voltage Range" is the newest terminology used by UL to identify the voltage range. Prior to this change, UL used the
terminology "Listed Voltage Range".

* RMS current ratings are per UL average RMS
method. UL max current rating is the maximum
RMS current within the listed voltage range
(16-33v for 24v units). For strobes the UL max
current is usually at the minimum listed voltage
(16v for 24v units). For audibles the max current
is usually at the maximum listed voltage (33v
for 24v units). For unfi ltered FWR ratings, see
installation instructions.
