Det-Tronics EQP Fire and Gas Detection/Releasing System - Manual (Page 93)

14.1 95-8533 4-16
Note
once a release sequence has been initiated
within the embedded logic, the sequence will
continue until it is complete.
When the embedded logic sequence is complete, a
“Manual Reset Required” status condition will be
reported by the IPM. User logic within the EQP
Controller must be utilized to send a “Reset”
command to the IPM that will reset all timers, latches,
etc. to their normal state.
If a Detector Electronics S3 Operator Interface Station
(OIS) is attached to the EQP Controller, the point
display for the IPM can be used to send a reset
command.
Note
the IPM will not accept a reset command if the
“Manual Release” input is in the “alarm” state.
EMBEDDED LOGIC – S3 CONFIGURABLE
OPTIONS
The IPM has various configurable options, selected
during node configuration in the S3 software
package.
Embedded Logic Selection: The IPM has 3
operation modes, Controller Only, Back-up Mode,
Embedded Only.
Controller Only: In this mode the I/O of the IPM will
be controlled from the EQP Controller only and
embedded logic is inactive.
Back-up Mode: (The default selection) the IPM I/O is
normally controlled by the EQP Controller but utilizes
embedded logic in accordance with the “Control
Transfer Sequence Description” to control its I/O
under certain circumstances.
Embedded Only: In this mode the IPM continuously
operates from its embedded logic. The status of all
IPM I/O is available to the EQP Controller but control
of the outputs are not; however, controller and S3
reset commands are accepted.
Detection Style – Single or Cross Zoned: A
software selection allows either “1 zone release” or “2
zone release” (cross-zoned) operation.
Manual Release Action – Delayed or Not Delayed:
A software selection allows the Manual Release input
of the module, channel 2, to be delayed or not
delayed. If not delayed, release is immediate. If
delayed, the signal will utilize the time delay selected
for the release circuits but with a 30-second
maximum.
Release Circuit Delay Selection: A time delay is
available from when the inputs (channels 2, 4 or 5) go
active until the releasing outputs (channels 7 and 8)
go active. The bell output (channel 6) is activated
immediately when an input becomes active. The time
delay selection choices are listed below:
0 Second
10 Seconds
20 Seconds
30 Seconds
40 Seconds
50 Seconds
60 Seconds
Note
Manual release is limited to 30 seconds, even if
40, 50 or 60 seconds time delay is selected.
Abort Mode Selection: The IPM abort input, channel
1, is software configurable to use any one of three
modes of operation. These three modes operate as
follows:
Mode 1: Upon activation, the delay timer will count
down to and hold at 10 seconds; upon release,
timer will continue to count down to zero. Only this
mode complies with UL 864.
Mode 2: Upon activation the delay timer will reset
to its initial value and on release will continue
counting down to zero.
IRI Mode: Functions similar to “Mode 1” except the
abort will only function if activated prior to a second
alarm.
Signaling Circuit Configuration – Bell Circuit
(SAM), Channel 6:
This output channel can be
software selected to any standard EQP Signal Audible
Module (SAM) configuration. In a cross-zoned mode,
selections are as follows:
One Zone Mode: The signaling circuit can be
configured to any standard SAM selection.
Two Zone Mode: In this mode the user must make
two selections. A standard SAM selection for when a
single detection circuit is in alarm and another
selection for when both detection circuits are in alarm.
