Notifier Series CH - Manual (Page 2)

Page 2 of 4 — DN-3468:A • 02/28/07
• Series NS Strobe products are listed under UL Standard
1971 for indoor use with a temperature range of 32°F to
120°F (0°C to 49°C) and maximum humidity of 93% (±
2%).
• Series NH horns are listed under UL Standard 464 for
audible signal appliances (indoor use only).
• “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.”
Application Notes for Current Table
1. The chimes are factory set in single-stroke (SS) mode.
They can be changed to vibrating (VIB) mode with jumper on
PC Board. SINGLE-STROKE OPERATION: The minimum
input pulse duration must be at least 160 ms “on” time and
160 ms “off” time. The chime will only operate once each
time it is pulsed. This mode is recommended for coded sys-
tems. VIBRATING OPERATION: Continuous input voltage
applied to the chime will activate the chime at one-second
intervals.
2. The volume and tone controls have been adjusted at
the factory to insure maximum dBA output. However, once
the mode is selected, the installer may want to fine-tune the
signal to better suit the application.
3. Anechoic dBA is measured in an anechoic chamber
with peak meter response. Reverberant dBA is rated per UL
Standard 464.
4. Chime inrush current is 0.100 A maximum with filtered
DC input (0.140 A with V RMS input voltage) with a time dura-
tion of 100 milliseconds.
CHIME dBA RATINGS
Sound level for CH70/CH90 is 83 dBA @ 10 ft (3.048 m)
anechoic room; dBA in a 10 ft (3.048 m) reverberant room is
52 dBA minimum to 58 dBA maximum.

NOTE: *RMS current ratings are per UL average RMS method. UL maximum current rating is the maximum RMS current within the
Listed voltage range (16-33Vfor 24V units). For strobes, the UL maximum current is usually at the minimum Listed voltage (16V for
24V units). For audibles, the maximum current is usually at the maximum Listed voltage (33V for 24V units). For unfiltered FWR rat-
ings, see installation instructions.
