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 Part 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.
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 30O C/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/60-80O
F.
Verify that wire sizes are adequate for all initiating and indicating 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
While installing a fire alarm system may make lower insurance
rates possible, it is not a substitute for fire insurance!
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. Further-
more, all types of smoke detectors - both ionization and photoelectric types, have
sensing limitations. No type of smoke detector can sense every 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.
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 supplied 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.

2.0 Installation
2.1 General Mounting Options
The cabinet may be either semi-flush or
surface mounted. The door is removable
during the installation period by opening
and lifting off the hinges.
The cabinet mounts using two key slots and
two additional 0.250" diameter holes
located in the backbox. The key slots are
located at the top of the backbox and the two
securing holes at the bottom.
Carefully unpack the system and check
for shipping damage. Mount the cabinet
in a clean, dry, vibration-free area where
extreme temperatures are not
encountered. The area should be readily
accessible with sufficient room to easily
install and maintain the panel. Locate the
top of the cabinet approximately five feet
above the floor with the hinge mounting on the left. Determine the number of
conductors required for the devices to be installed. Sufficient knockouts are provided
for wiring convenience. Select the appropriate knockout(s) and pull the required
conductors into the box. Note that there are no knockouts on the left (hinged) side of
the cabinet. All wiring should be in accordance with the National and/or Local codes
for fire alarm systems.
• Refer to Figures 2-1 and 2-2.
• Open the door and lift the door off the pin hinges.
• Remove AC wiring.
• Remove the main PC board assembly by unscrewing the five screws in the
corners of the board. Two standoffs support the board in the center. Set the board
aside in a safe, clean place. Avoid static discharge which may damage the
board.
• Mark and predrill holes for the top two keyhole mounting bolts using the
dimensions shown.
• Install two upper fasteners in the wall with the screw heads protruding.
• Using the upper 'keyholes', mount the backbox over the two screws.
• Mark and drill the lower two holes.
• Mount backbox, install remaining fasteners and tighten.
• When the location is dry and free of construction dust, reinstall the main PC
board.

CAUTION: Several different sources of power can be connected to this panel.
Disconnect all sources of power before servicing. The panel and associated
equipment may be damaged by removing and/or inserting cards, modules, or
interconnecting cables while this unit is energized.
Primary Power Source (AC) and Earth Ground Connections
AC power connections are made inside the control panel cabinet. Primary power
source is 120 VAC, 60 HZ, 1.2 amps and for the MS-5024E is 220/240 VAC, 50 Hz,
0.6 amps. Run a pair of wires (with ground conductor) from the protected premises
main breaker box to the orange and black primary leads of the MS-5024 transformer.
As per the National Electric Code, use 14 AWG (1.6 mm O.D.) or heavier gauge
wire with 600V insulation. No other equipment may be connected to this circuit. In
addition, this circuit must be provided with overcurrent protection and may not
contain any power disconnect devices. A separate Earth Ground connection must be
made to ensure proper panel operation and lightning and transient protection.
Connect the Earth Ground wire (minimum 14 AWG) to the grounding stud indicated
by the ground symbol label. Note: Do not use conduit for the Earth Ground
connection since this does not provide reliable protection.
Secondary Power Source (Batteries)
Observe polarity when connecting the battery. Connect the battery cable to J1 on the
main circuit board using the plug-in connector provided. The battery charger is
current limited and capable of recharging sealed lead acid type batteries. The charger
shuts off when the system is in alarm. See Appendix A for calculation of the correct
battery rating. CAUTION: Battery contains sulfuric acid which can cause severe
burns to the skin and eyes, and can destroy fabrics. If contact is made with sulfuric
acid, immediately flush the skin or eyes with water for 15 minutes and seek
immediate medical attention.

24 VDC filtered, resettable power for 4-wire
smoke detectors can be obtained from TB4
Terminals 3 (+) and 4 (-).
*Non-resettable Power (300 mA)
24 VDC filtered, non-resettable
power can be obtained from TB4
Terminals 1 (+) and 2 (-).
Figure 2-4: Auxiliary Power Connections
The control panel has five zone input circuits. The maximum loop resistance limit
for each is 100 ohms. All field wiring of each zone is supervised for opens and
ground faults. Both conditions are visually and audibly annunciated as well as
communicated to a Central Station.
Each zone is a Style B Initiating Device Circuit (IDC) designed to accept any
Normally Open contact device and conventional 2-wire, 24 volt smoke detectors.
Each zone is power limited to 7.26 mA in standby and 42 mA in alarm. Zone 3 may
also be configured as a Style D Initiating Device Circuit. Figure 2-5 illustrates
typical circuit connections.
Note: All five initiating zones may be converted to Style D (Class A) by using a CAC-
5F Class A Converter module (refer to Figure 2-15).
Zones 1-5 may be programmed as shown below. The factory default is 2-wire smoke
detector for all zones.
• 2-wire Smoke Detector (factory default)
• Pull Station
• Normally Open Contact Device(s)
• Supervisory
• Supervisory, Auto-Resettable
Zone 3 may also be programmed as:
• Waterflow Silenceable
• Waterflow, Non-Silenceable
Note: A maximum of five waterflow devices may be used on zone 3 per NFPA 72.
Four-wire smoke detectors may be connected to any zone. Resettable power is
provided via terminals TB4, 3 and 4.
It is allowable to mix an assortment of device types (ie, smoke detectors, heat
detectors, pull stations) on any zone. However, this is not recommended since
specific and detailed reports will not be possible. For example, the report of general
fire alarm versus pull station fire alarm or smoke detector fire alarm.
