General Description
Informer100 Speaker (Models I-IP100ACX and I-IP100DCX)
General Description
Introduction
The Informer100 Speaker is an indoor and outdoor IP-enabled 100-watt speaker that
can be used in hazardous (classied) locations. Use the Informer100 as a warning and
alert device with both audible and visual indicators. The audible capabilities include
locally stored high-quality, high-powered tones and voice. The visual indicators include
the use of message board/scrolling display sign support and strobes, lights and beacons.
The Informer100 can be equipped with up to four local initiation devices (switches)
to activate the unit locally and to the Commander controller for mass notication
communications.
The Informer100 Speaker has an internal 100-watt amplier/driver to deliver tone
warnings and intelligible voice messages from Informer100 stored memory. The
Informer100 also has several unique capabilities when working with the Federal Signal
Commander software. Using Commander software, the Informer100 can play text-to-
speech, stream WAV les or can broadcast live PA. In addition, Commander software can
perform a talk/listen to individual Informer100s to allow call-box type communications.
The Informer100 also has remote volume control for optimizing sound levels across
your alerting area. The remote volume control also includes an ambient noise monitoring
capability to automatically adjust volume depending on external noise levels.
The Informer100 allows connection of up to four external switches to activate predened
alert events. The Informer100 can be programmed and congured as a standalone device
to only use the inputs to activate the Informer100. This may be useful if the location has
no network connectivity, but where voice and tone alerts from locally activated inputs is
required. The Informer100 can be networked later and the activations can be brought into
the Commander system for full system capability. When the Informer100 is networked
using the Commander software, alerts initiated at the Informer100 can be used to activate
other devices. The Commander software system can also alert emergency personnel via
email, SMS and handheld radios using optional messaging software.
The Informer100 includes two relay outputs for controlling strobes or other devices. The
Informer100 has a ½-inch NPT opening on the top of the speaker for simple installation
of pipe mount devices. The bottom of the speaker has three ¾-inch NPT openings to
allow access to power, LAN, relay outputs, and activation inputs. The Commander
system allows multiple congurations for activation of the relays during alerts.
The Informer100 is designed for outdoor use and large indoor structures. It can be
powered from 120/240 Vac or 24 Vdc depending on the model purchased. All wiring
interfaces are accessible via internal connectors and built-in NPT entrances for quick and
easy installation.
The Informer100 comes with an adjustable stainless steel wall mount bracket that allows
the angle of the speaker to be adjusted. Optional pole mount brackets are available for
small and large diameter poles.

Wiring Power to the Control Board
JP6, JP7, JP8 and JP9 are all connected in parallel. Federal Signal recommends using
JP8 as the AC or DC input to allow room for wires coming in from the ¾" NPT opening.
When power is supplied to JP8, it is connected through the PCB to the other three
connectors. If a connector is not being used, it is recommended to leave the connector
on the PCB. With I-IP100ACX units, JP9 is wired from the factory to the power supply
PCB. With the I-IP100DCX units, JP9 is wired to the amplier PCB. Use JP6 and JP7
to wire external lights or strobes through JP4, which is a normally open relay. Typical
installation would use voltage to be wired through the JP4 relays contacts.
NOTE: Current draw from JP6, JP7, and JP4 must not exceed 8.5 ampere AC or
5.0 ampere DC Max Combined Load.
