Module Bay Description
Transponder model 4100-9600 includes a bay
assembly, a power distribution interface module (PDI), a
Basic Transponder Interface Module, and an interconnect
harness. Communications with the host fire alarm control
panel are via a Remote Unit Interface (RUI) connection
that allows for up to 2500 ft (762 m) distance. RUI can
communicate with up to a total of 31 remote devices and
can be either Style 4 or Style 7 communications.
Transponder model 4100-9601 substitutes a Local
Mode Transponder Module for the Basic Transponder
Module.
Optional Expansion Bays each include a PDI and
accept a variety of optional modules (refer to list starting
on page 4).
The Battery Compartment (bottom) accepts two
batteries, up to 50 Ah, that can be mounted within the
cabinet. Battery mounting does not interfere with
available module space. A power supply with battery
charger is required for each battery set.
Packaging Availability
Modules are power-limited (except as noted, such as
relay modules)
Enclosure are available for one, two, or three bay sizes
or for cabinet rack mounting
Boxes and solid doors are available in beige or red
(ordered separately)
Up to eight close-nippled cabinets can be connected at
one transponder location (close-nippled is mounted
within 20 ft (6 m) and with interconnecting wiring
enclosed in conduit)
Refer to document S4100-0037 for enclosure details
Local Mode Control Operation
Default Stand-Alone Operation. In the event of a
communications loss with the host fire alarm control
panel, model 4100-9601 MINIPLEX Local Mode
Transponders provide fire alarm response default
operation for its connected devices and appliances per the
following.
Input Operation. During local mode operation,
TrueAlarm initiating devices connected to the transponder
will cause an alarm at their least sensitive alarm threshold.
Photoelectric sensors will alarm at 3.7%/ft smoke
obscuration
Ionization sensors will alarm at 1.3%/ft obscuration
Heat sensors will alarm at a fixed temperature of 135° F
(57° C)
TrueAlarm device LEDs will be activated to indicate a
device in alarm
Local Mode Control Operation (Continued)
Notification Operation. Fire alarm conditions reported
against a fire alarm point type within a transponder in
local mode will cause all notification appliance circuits in
that transponder to:
Sound a general alarm temporal pattern horn tone
Activate visible notification appliance circuits
Local Mode Module Support. Local mode operation
provides support for the following 4100ES modules:
Enhanced Power Supplies (EPS+/EPS) including
on-board IDNAC SLCs
IDNet 1+ addressable device circuits, including those
on-board the EPS+, IDNet 1+ expansion modules, and
the Quad IDNet Isolator Module
Expansion Power Supplies (XPS) including on-board
NACs and expansion signal modules, operated at a
temporal pattern
4100ES amplifiers will provide their on-board horn tones
(500 Hz) at a temporal pattern through their on-board
amplifier NACs
Firefighter Telephone control modules in local mode
Local Mode Operation Module Exclusion. Modules
not listed above but that are listed as compatible with
MINIPLEX transponders per this document, do not
interfere with local mode operation but are not supported
during local mode operation.
Local Mode Controller
Operation. During local mode operation, an optional
Local Mode Controller will indicate status (see illustration
below) and can be enabled using a keyswitch to perform
local alarm silence or reset. If alarms occurring during local
mode are reset using a Local Mode Controller, upon
restoration of communications, those alarms will not be
sent to the master controller. If alarms are still present
upon restoration of communications, then the alarm
condition will be reported and host fire alarm control panel
programmed alarm functions will occur. When
communications are re-established, the local mode
transponder restores automatically.
Mounting. Local Mode Controllers are mounted on
three-gang plates, are available in beige or red, and for
either flush or semi-flush mounting. (See page 7 for
details).
