u Plug‑in design with tamper-resistant, rainproof

(NEMA 3R) construction

The SS‑P2RK Horn Strobe, one of the System Sensor
SpectrAlert Advance notification appliances, simplifies
installations with features such as plug‑in designs,
instant feedback messages to ensure correct
installation of individual devices, and field‑selectable
candela settings. This horn strobe is designed for
outdoor wall‑mounted applications.
SpectrAlert products can be used in either DC or
full‑wave rectified (FWR) systems (12 V or 24 V). If
required, the SSMDL module can be used to provide
synchronization.

Notice

Full‑wave Rectified (FWR) voltage is a
non‑regulated, time‑varying power source that is
used on some power supply and panel outputs.

u Field‑selectable settings of 15 cd, 15/75 cd, 30 cd,

75 cd, 95 cd, 110 cd, and 115 cd

u Horn rated at 88 dbA or greater at 16 V

u Rotary switch selection for horn tone and one of

three volumes

u Shorting spring on mounting plate for continuity

check before installation

Notice

SpectrAlert products set at 15 cd and 15/75 cd
automatically work on either 12 V or 24 V power
supplies. The products are not listed for 12 V
operating voltages when set to any other candela
settings.

Functions

Horn

The horn has three volume options and an option to
switch between a temporal Code 3 pattern and a
non‑temporal (continuous) pattern. These options are
set by a multiple position switch.

Strobe

When wired as a primary‑signaling notification
appliance, the strobe complies with the Americans
with Disabilities Act (ADA) requirements for visible
signaling appliances, flashing at 1 Hz over the strobe's
entire operating voltage range. The strobe light
consists of a xenon flash tube and associated lens and
reflector system.

For 24 V applications, the total number of strobes on a
single NAC must not exceed 40, with a maximum loop
resistance of 120 Ω. For 12 V applications, the total
number of strobes must not exceed 12, with a
maximum loop resistance of 30 Ω.

Mounting Considerations

Notice

These strobes are for wall mounting only!

For outdoor use, these strobes wall mount on the
supplied outdoor back box.

Wiring Considerations

The input terminals on the universal mounting plate
accept solid wires between 12 AWG (2.3 mm) to
18 AWG (1.2 mm).
