General Description
Informer-IP Desk Mount (Model I-IP-IO Series C)
Federal Signal www.fedsig.com
General Description
Introduction
The Informer-IP Desk Mount is an intercom, a warning device, and an alarm initiation
point that connects to an Ethernet network. An internal speaker is used to provide clear
two-way voice communications between control and monitoring points and distributed
locations. You can trigger two dierent alerts at the Informer-IP using the contact closure
input and the ALERT button.
The Informer-IP has an audio output for connecting to existing PA systems and two relay
outputs to control strobes or other devices. An RS232 port is available for driving an
optional scrolling message display. The Informer-IP provides seven standard alert tones
and can store up to 4,000 voice or tone messages with 17 hours of total prerecorded tone
and voice alerts.
You can wall mount the unit or have it sit on a desktop. You can power it through Power

Determine a Suitable Location
When choosing a location for the Informer-IP, consider the following criteria:
• Place as far as possible from electrically noisy electronic devices to avoid
interference. Examples of noisy devices may include microwave ovens, motor-driven
devices, light ballasts, and electrical switching devices.
• Requires a connection to a wired Ethernet network. Ethernet wire runs must be less
than 328 feet (100 meters) from the nearest network switch.
• Place in an area where you can hear the speaker when the Informer-IP is activated.
You can check the warning tone level by holding the VOLUME up and down buttons
until the desired level is reached. If the coverage area is large, multiple Informer-IP or
external amplifiers and speakers may be required to provide adequate warning.
• Position to keep the unit at least 6 inches (15.24 cm) away from the listener’s ears to
avoid potential hearing damage.
• Do not use near water, for example, near a bathtub, washbowl, kitchen sink, laundry
tub, in a wet basement, near a swimming pool, rain, or similar environments.
• Place where it will not be inadvertently covered or moved. A permanent wall mounting
is recommended after you have found a suitable location. Alternatively, you may place
the Informer-IP on a flat, level surface.
• Place within 6 feet (1.8 meters) of an AC power receptacle to eliminate the need for an
extension cord unless a Power over Ethernet (PoE) connection is available.
