INTRODUCTION 1.0 Introduction to the IPS Information on the operation, installation, and maintenance of the Whelen Engineering Company’s In-Plant Personnel Warning System (IPS) is provided in this technical manual. The IPS-400 and the IPS-800 are essentially the same. The IPS- 400 has a single 400 watt amplifier, while the IPS-800 has two. This means that the IPS-800 can drive 800 watts of audio power versus 400 watts for the IPS-400.
Section 2 IPS CONTROLLER DESCRIPTION 2.0 Controller System Description This section provides a general description of the IPS siren controller, including a physical description and a functional description of the system. The functional description includes system activation methods, timing selection, signal and audio characteristics, and power requirements.
2.2 Operational Description As previously mentioned, the IPS is a self-contained, microprocessor-controlled warning system capable of generating six standard siren warning signals, public address broadcast, and strobe light signaling. The standard warning signals-- WAIL, ALERT, ATTACK, AIR HORN, HI/LO, AND WHOOP--are described in detail in Section 4.1.1. The IPS is powered by a 115 VAC, 1.5 Amp service.
Section 3 SPECIFICATIONS 3.0 General Specifications The table below refers to general specifications for an IPS control cabinet. Specifications for speakers and strobe lights are available upon request. IPS Specifications PHYSICAL Height: 32.5 inches DIMENSIONS (not including mounting flanges) Width: 20.0 inches Depth: 12.0 inches WEIGHT IPS-400: 120 lb.
Section 4 MODULE DESCRIPTION 4.0 IPS Module Descriptions This section provides an overview of the individual electronic modules in an IPS. • ESC-864 (Controller) • Power Amplifier(s) • System Driver Board • Battery Charger • Batteries 4.1 ESC-864 (Controller) The ESC-864 Controller is the microprocessor-based core of the IPS. The ESC-864 houses the following: local pushbuttons and LED indicators, the ESC-864 controller circuit board, the tone generator,...

Control or Indicator Control or Indicator Function input from the tone generator's input, eliminating outside interference. Removing the microphone from the microphone jack restores the remote radio audio input. XMIT The XMIT LED, when illuminated, indicates that the ESC-864 is actuating the IPS transmitter push-to-talk (PTT) circuit and is transmitting data or a test tone.
4.1.2 ESC-864 Controller Circuit Board The ESC-864 Controller board allows for local activation of warning signals, plus remote control interfacing. It also monitors system status and provides visual status indicators as described in the previous tables. The ESC-864 PC board controls the tone generator.

The ESC-864 board reports status information to a central control point in response to the following alarm conditions: - a change-of-state alarm (user selectable on/off) - instant response to individual activation (user selectable on/off) or - response to individual interrogation. In the event of an alarm condition, the ESC-864 board will transmit its status report three times to ensure that the message is received.
electrical circuit between a power amplifier channel and its respective speakers. The LEDs, indicate a complete circuit from the respective power amplifier channel to the speakers and back when the power amplifier is in operation. An active LED indicates that the power amplifier channel, system driver board, speaker wires, and speaker(s) are functioning when a warning signal tone or public address mode is active.

5.2 Receiving/Unpacking the IPS An IPS is typically shipped with the following items packed on a single shipping pallet: (a) two, 12 volt, Gel type batteries (31 AH for an IPS-400 or 55 AH for an IPS-800; and (b) the IPS cabinet with the appropriate electronics, as ordered.
5.3a Installation of the “Type C” Cabinet For “Type C” cabinet installation only The IPS cabinet is typically mounted to an inside wall of a building. The cabinet is equipped with two mounting flanges on the top and two mounting flanges on the bottom, as shown in the drawing. The top flanges have two 7/16”...
5.4 Conduit Openings for the IPS Cabinet The installer must punch entry holes in the IPS cabinet. The holes are typically made on the left side of the cabinet, as shown in the drawing. Note: The location of the holes, the size of the holes and the number of holes is left to the installers discretion.
5.5 AC Wiring Make sure the battery charger is unplugged from the AC outlet in the left rear corner of the control cabinet. Route the AC service wire through the cable clamp on top of the box. Make the AC connections to the outlet, according to local electrical codes.
5.6 Speaker Wiring speakers audio connections are made through the .325 CENTERS System Driver Board, located on the left side of the back wall of the IPS cabinet. PC. BD #67729 SPEAKER AUDIO 1+ SPEAKER AUDIO 1- The upper most terminal block is SPEAKER AUDIO 2+ TB1.
5.7 Radio Option Locate the antenna so that it is clear of any obstructions. Ground the antenna bracket using a minimum of 4 AWG copper wire to a suitable earth ground. If the unit is equipped with a transmitter, a coax protector has been provided. The protector is shipped in the battery compartment.
Section 6 BATTERIES 6.0 Battery Installation As previously mentioned, an IPS-400 comes with two 31 Amp-hour batteries. These fit as shown in the drawing. The IPS-800 comes with two 55 Amp-hour batteries. These are larger than the 31 Amp-hour batteries. They must be rotated 90 degrees to be installed.
Section 7 CONTROLLER PROGRAMMING 7.0 ESC 864 Controller Programming This section covers user programmable features of the ESC-864 controller, in the IPS. A number of parameters are factory set in Electronically Erasable Programmable Read Only Memory (E PROM) others are controlled by Dip Switch settings.
