Installation Precautions–
Adherence to the following will aid in problem-free installation with long-term reliability:
WARNING -
Several different sources of power can be connected to
the fire alarm control panel.
Disconnect all sources of power before
servicing. Control unit and associated equipment may be damaged by
removing and/or inserting cards, modules, or interconnecting cables
while the unit is energized. Do not attempt to install, service, or
operate this unit until this manual is read and understood.
CAUTION -
System Reacceptance Test after Software Changes: To
ensure proper system operation, this product must be tested in
accordance with NFPA 72-1993 Chapter 7 after any programming
operation or change in site-specific software. Reacceptance testing is
required after any change, addition or deletion of system components,
or after any modification, repair or adjustment to system hardware or
wiring.
All components, circuits, system operations or software functions
known to be affected by a change must be 100% tested. In addition, to
ensure that other operations are not inadvertently affected, at least
10% of initiating devices that are not directly affected by the change,
up to a maximum of 50 devices must also be tested and proper system
operation verified.
This system meets NFPA requirements for operation at
0-49OC/32-120OF and at a relative humidity of 85% RH
(non-condensing) at 30OC/86OF. However, the useful life of the
system's standby batteries and the electronic components may be
adversely affected by extreme temperature ranges and humidity.
Therefore, it is recommended that this system and its peripherals be
installed in an environment with a nominal room temperature of
15-27OC/60-80OF.
Verify that wire sizes are adequate for all initiating device loops.
Most devices cannot tolerate more than a 10% I.R. drop from the
specified device voltage.
Like all solid state electronic devices, this system may operate
erratically or can be damaged when subjected to lightning induced
transients. Although no system is completely immune from lightning
transients and interferences, proper grounding will reduce
susceptibility.
Overhead or outside aerial wiring is not recommended,
due to an increased susceptibility to nearby lightning strikes.
Consult
with the Technical Services Department if any problems are
anticipated or encountered.
Disconnect AC power and batteries prior to removing or inserting
circuit boards. Failure to do so can damage circuits.
Remove all electronic assemblies prior to any drilling, filing, reaming
or punching of the enclosure. When possible, make all cable entries
from the sides or rear. Before making modifications, verify that they
will not interfere with battery, transformer and printed circuit board
location.
Do not tighten screw terminals more than 9 in-lbs. Over tightening
may damage threads, resulting in reduced terminal contact pressure
and difficulty with screw terminal removal.
This system contains static-sensitive components Always ground
yourself with a proper wrist strap before handling any circuits so that
static charges are removed from the body. Use static suppressive
packaging to protect electronic assemblies removed from the unit.
Follow the instructions in the installation, operating and
programming manuals. These instructions must be followed to avoid
damage to the control panel and associated equipment. FACP
operation and reliability depend upon proper installation.
Fire Alarm System Limitations
An automatic fire alarm system - typically made up of smoke
detectors, heat detectors, manual pull stations, audible warning
devices and a fire alarm control with remote notification capability can
provide early warning of a developing fire. Such a system, however,
does not assure protection against property damage or loss of life
resulting from a fire.
Any fire alarm system may fail for a variety of reasons:
Smoke detectors may not sense fire where smoke cannot reach the
detectors such as in chimneys, in walls, or roofs, or on the other side of
closed doors. Smoke detectors also may not sense a fire on another
level or floor of a building. A second floor detector, for example, may
not sense a first floor or basement fire. Furthermore, all types of
smoke detectors - both ionization and photoelectric types, have
sensing limitations. No type of smoke detector can senseevery kind of
fire caused by carelessness and safety hazards like smoking in bed,
violent explosions, escaping gas, improper storage of flammable
materials, overloaded electrical circuits, children playing with matches,
or arson.
IMPORTANT!
Smoke detectors must be installed in the same room
as the control panel and in rooms used by the system for the
connection of alarm transmission wiring, communications, signaling
and /or power.
If detectors are not so located, a developing fire may
damage the alarm system, crippling its ability to report a fire.
Audible warning devices such as bells may not alert people if these
devices are located on the other side of closed or partly open doors or
are located on another floor of a building.
A fire alarm system will not operate without any electrical power. If
AC power fails, the system will operate from standby batteries only for
a specified time.
Rate-of-Rise heat detectors may be subject to reduced sensitivity
over time. For this reason, the rate-of-rise feature of each detector
should be tested at least once per year by a qualified fire protection
specialist.
Equipment used in the system may not be technically compatible
with the control panel. It is essential to use only equipment listed for
service with your control panel.
Telephone lines needed to transmit alarm signals from a premise to a
central monitoring station may be out of service or temporarily
disabled.
The most common cause of fire alarm malfunctions, however, is
inadequate maintenance. All devices and system wiring should be
tested and maintained by professional fire alarm installers following
written procedures supplies with each device. System inspection and
testing should be scheduled monthly or as required by National and/or
local fire codes. Adequate written records of all inspections should be
kept.
FCC Warning
WARNING: This equipment generates, uses and can radiate radio
frequency energy and if not installed and used in accordance with the
instruction manual, may cause interference to radio communications,
It has been tested and found to comply with the limits for class A
computing device pursuant to Subpart B of 15 of FCC Rules, which is
designed to provide reasonable protection against such interference
when operated in a commercial environment. Operation of this
equipment in a residential area is likely to cause interference, in which
case the user will be required to correct the interference at his own
expense.
Canadian Requirements

,QWURGXFWLRQ The XP Series Transponders provide the Fire Alarm Control Panel with an efficient
multiplex subsystem capability. XP Transponder communicates with the FACP and
functions as a data-gathering panel for alarm Initiating Device Circuits (IDC) and as a
remote switching center for Notification Appliance Circuits (NAC), telephone circuits
or relays. The XP Series Transponder is designed to be used anywhere a cost-effective,
remote data-gathering, control panel is needed. The XP Transponders are extremely
effective in both high-rise and low-rise buildings where power losses over long wiring
distances dictate the use of remote control equipment, amplifiers, or audio/visual power
supplies.
The Initiating Device Circuits of the XP Transponder may be used to monitor multiple
zones of conventional two-wire and four-wire smoke detectors and normally open
contact initiating devices. The Notification Appliance Circuits may be used to control
multiple zones consisting of horns, speakers, two-way fire fighter's telephones, or dry
contact relays.
Each XP Transponder communicates with, and is controlled by, a Signaling Line
Circuit (SLC) loop of the host FACP. If communication between the control panel and
the XP Transponder is lost, the XP Transponder will automatically switch over to
degraded local mode operation (if so programmed), in which it functions as an
independent Fire Alarm Control Panel.
To the control panel, the XP Transponder appears to be a cluster of sequentially
addressed monitor and control modules, starting from a base SLC address (one module
SLC address for every XP point). The XP may share the same SLC loop with other
addressable devices such as intelligent detectors or addressable modules. Multiple XP
Transponders may be placed on the same SLC loop provided the module address
capacity of 99 is not exceeded.
The XP Series Transponders can be used with the following

The MPS-24A and MPS-24AE Main Power supplies are capable of powering the XP
Transponder continuously during non-alarm and alarm conditions. A total of 3.0 amps
(internal) @ 24 VDC filtered is available from the MPS-24A/MPS-24AE main power
supply for operating the system during non-fire alarm conditions. Up to 6.0 amps @ 24
VDC can be drawn from the MPS-24A/MPS-24AE during an alarm condition, when
the transponder is functioning in local mode. If the XP Transponder is being used as a
peripheral panel of an FACP, only a total of 3.0 amps may be drawn from the MPS-
24A/MPS-24AE. This is because the charger circuit of the MPS-24A is not turned off
during alarm unless the transponder is operating in local mode and not communicating
to the FACP or the charger is disabled because an NR45-24 external charger is
connected and JP1 has been cut. If the charger is operating there is only a 3.0 amp
capacity for both internal (transponder modules) load and external load such as
notification appliances. Six amps are available continuously (alarm and non-alarm)
when JP1 is cut and the external NR45-24/NR45-24E battery charger is employed, in
both peripheral and local mode. JP2 must be cut for all Transponder applications!

The MPS-24A requires 120 VAC, 50/60 Hz primary power and the MPS-24AE requires
220/240 VAC, 50/60 Hz primary power. The transponder requires connection to a
dedicated AC fire alarm circuit, which must be labeled “FIRE ALARM”. This AC
circuit must connect to the line side of the main light and power feed of the protected
premises. No other equipment may be powered from the fire alarm circuit. The AC
circuit wire run must run continuously, without disconnect devices, from the power
source to the transponder power supply. Overcurrent protection for this circuit must
comply with Article 760 of the National Electrical Code (NEC) as well as local codes.
Use 12 AWG (3.25 mm2) wire with 600 volt insulation for this circuit. With the circuit
breaker at the main power distribution panel turned off, remove the plastic insulating
cover from Terminal Block TB1 on the MPS-24A/MPS-24AE. Connect the system
primary AC power source. Connect the service ground to TB1-3 and ground the power
supply assembly to the cabinet with a chassis ground cable (71073) from TB1-3.
Connect the AC Neutral line to TB1-4 and the AC Hot wire to TB1-6. Do not route AC
wiring in the same conduit as other XP Transponder circuits. After completion of these
connections, reinstall the plastic insulating cover over the terminal block. Leave the

The MPS-24B/MPS-24BE automatically employs Ground Fault Detection (required in
Canada) unless resistor R55 is removed. This feature must be disabled on all but one
power supply if multiple power supplies are present and share a common signal
reference.

Up to 200 mA of current for 24 VDC four-wire smoke detectors can be drawn from
TB2 Terminals 1 (+) and 2 (-) on the MPS-24B/MPS-24BE. Power is removed from
these terminals momentarily during system reset (unless jumper JP1 is removed to
configure the output for continuous annunciator power). This filtered four-wire smoke
detector power is power limited but must be supervised via an end-of-line power
supervision relay. This power supervision relay is energized by the four-wire smoke
detector power and the relay contact must be wired in series with an XPM-8 or XPM-
8L IDC.

Internal power for the XP Transponder is provided via the Power Harness 75100 or
75099. Connect this harness from P2 on the MPS-24B/MPS-24BE to P9 on the XPP-1.
Supervisory information is transferred between the XPP-1 and the MPS-24B/MPS-
24BE through the Supervisory Power Ribbon Cable (71031) which is connected from
P7 on the XPP-1 to P3 on the MPS-24B/MPS-24BE.
