EQ3740ipm intelligent protection module
The IPM (see Figure 2-13) is designed to provide
continuous and automated local area fire protection,
while monitoring system operation through continuous
supervision of its Inputs/Outputs and Local Operating
Network/Signalling Line Circuit (LON/SLC) connection to
the EQP controller.
In addition the module contains a unique “embedded
logic program” that if enabled during configuration
allows the IPM to perform local area protection in a
“back-up mode” without controller interaction.
The IPM utilizes eight pre-configured Input/Output (I/O)
channels to perform its monitoring, supervision and
mitigation functions.
On the input side, three supervised channels provide
connections for an Abort station, a Manual Release
station and a Supervisory device. Two additional input
channels (zones) provide connections for “two-wire”
conventional (non-relay based) smoke and heat
detectors.
On the output side, three supervised outputs provide
connections for a notification appliance such as a
bell, horn or lamp and two releasing circuits for a main
and reserve or secondary agent release.
Each channel on the module is provided with
individual indicators for active and fault conditions.

Data sheet (form number 90-1184) for additional

EQ3750asH addressable smoke & Heat module
The Addressable Smoke and Heat (ASH) Module (see
Figure 2-14) is an interface device designed to provide
continuous and automated fire protection for the EQP
system.
The ASH module is located directly on the LON of the
EQP system, with a loop of up to 64 addressable devices
tied into the ASH module. This allows all of the flame,
gas, and addressable smoke and heat detectors to run
on one system, enabling the EQP controller to annunciate
a fire alarm from either its own LON based I/O, or from the
connected addressable smoke and heat detection loops.
The EQP controller can support up to 10 ASH modules.
The ASH module can support a variety of Apollo Discovery
and XP95 devices, including smoke, heat, manual call,
sounders, beacons and I/O modules. The addressable
devices are configured individually via the S 3 software.
To ensure reliable system operation, the ASH module
continuously monitors its input and output circuits for
opens and short circuit conditions.
During normal operation, the ASH module continuously
checks the loop for fault conditions and executes user
defined programmed logic that coordinates the control
of the field devices. The ASH module reports any device
based fault and alarm conditions to the EQP controller.
The EQP Controller continuously monitors the status of
the ASH module, as well as the status of each device
connected to the ASH module. ASH module alarm and
fault status conditions are logged in the EQP controller.
System status can be determined using S 3 software or
the status indicators on the ASH module, where LEDs
annunciate power on, faults, or an active device on the
loop.
Refer to the ASH module instruction manual (form
number 95-8654) for additional information.
