exists, they cannot provide the intended audible warning. It is imperative that
knowledgeable people, who are provided with the necessary information, be
available at all times to authorize the activation of the sirens.
• When sirens are used out of doors, people indoors may not be able to hear the
warning signals. Separate warning devices or procedures may be needed to warn
people indoors eectively.
• The sound output of sirens is capable of causing permanent hearing damage. To
prevent excessive exposure, carefully plan siren placement, post warnings, and
restrict access to areas near sirens. Review and comply with any local or state noise
control ordinances as well as OSHA noise exposure regulations and guidelines.
• Activating the sirens may not result in people taking the desired actions if those to
be warned are not properly trained about the meaning of siren sounds. Siren users
should follow FEMA recommendations and instruct those to be warned of corrective
actions to be taken.
• After installation, service, or maintenance, test the siren system to confirm that it is
operating properly. Test the system regularly to confirm that it will be operational in

RF Receiver
The Receiver Module (RF) is a fully shielded receiver that plugs into the FC controller. It is
available in High (FCH) and UHF (FCU) bands.
The FC control board provides power and adjustments for the RX frequency of the
receiver. The radio receiver provides over the air transmission signals to the FC Controller
for decoding. The FC Controller can decode two-tone sequential, DTMF, EAS, POCSAG,
and digital AFSK.
RF Receiver Features
The RF Receiver has the following features.
• Small size
• Rugged construction using surface mount components
• Shielded receiver assembly to prevent interference
• Available in VHF and UHF bands
• Low current draw, excellent for battery-powered operation
• Synthesized frequency selection
• Wide temperature operating range
• Excellent selectivity, able to receive its signal while rejecting others
• Clean, low distortion recovered audio
• Noise-based squelch circuit does not open receiver in high radio noise environments,
such as near computers
POCSAG Decode
The FC Controller can decode POCSAG messages when equipped with a radio receiver.
All POCSAG messages contain a Receiver Identity Code (RIC) or CAP code. This indicates
which unit or group of units a message is intended for. The unit must have its RIC
configured before it responds to a message.
The Standard Format for Federal Signal POSAG codes consists of a five-character
numeric message preceded by an open bracket “[” and followed by a closed bracket
“]” for a total of seven characters. The first three numbers are the unit number. Any unit
number less than 300 activates only that unit number. A unit number of 300 activates all
units. Unit numbers of 301 to 316 activate all units in zones 1 to zone 16, respectively. The
unit must be configured for the zone in which it is to function.
The last two numbers in the message are the function number (01 through 06), which
activates functions 1 through 6. Function numbers 96, 97, 98, and 99 activate Poll All,
Reset, Quiet Test, or Cancel, respectively.
