Synchronization
Although the AVS44 modules can be used with these
devices, the AVSM modules are recommended in loops
where no HS24 or ST24 devices are used.
Wiring
Notice
Do not use these strobe units in coded or pulsed
signaling circuits.
The input terminals accept wires with diameters
between 18 AWG and 12 AWG (ISO 0.75 mm
2
and
4 mm
2
).

Horn Ratings
Temporal Code 3, 2400 MHz Mode
Audible Device Current
(maximum):
22 mA RMS
45 mA FWR
Sound Output (maximum
range)
at 10 ft (3 m):
High output: 83 dBA
Low output: 75 dBA
Temporal Code 3 Mechanical Mode
Audible Device Current
(maximum):
23 mA RMS
43 mA FWR
Sound Output (maximum
range)
at 10 ft (3 m):
High output: 81 dBA

*Operating the horn in this mode at this voltage does not meet the
minimum UL reverberant sound level required for public mode fire
protection service. These settings are acceptable only for private mode
fire alarm use. Chime mode is only acceptable for private use.
Continuous 2400 MHz Mode
Audible Device Current
(maximum):
22mA RMS
45 mA FWR
Sound Output (maximum
range)
at 10 ft (3 m):
High output: 86 dBA
Low output: 78 dBA
Continuous Mechanical Mode
Audible Device Current
(maximum):
23 mA RMS
43 mA FWR
Sound Output (maximum
range)
at 10 ft (3 m):
High output: 84 dBA
Low output: 76 dBA
Notice
The sound output for the temporal (Code 3) mode
is rated lower because the time that the horn is
off is averaged into the sound output rating. While
the horn is producing a tone in Temporal mode,
its sound pressure is the same as the Continuous
mode.
