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.

SPECIFICATIONS
2.0 FEATURES
MET-1 features are provided in the following list and are described in paragraphs 2.1 through 2.5.
 Status Displays
 Diagnostic Indicators
 Switches
2.1 STATUS DISPLAYS
The MET-1 has a four digit display which provides test status and results. A second display indicates the test
number and whether the test is for bus mode or point-to-point operation.
2.2 MODE INDICATORS
The MET-1 has two green indicators which illuminate to distinguish between receive and transmit modes.
2.3 SWITCHES
The MET-1 has one power switch and two push-buttons. The SELECT push-button is used to select the desired
test and port. The START push-button begins the selected test. Either button can be used to stop a test once it
has started.
2.4 DATA PORTS
The MET-1 has two isolated data ports to receive or transmit data over NOTIFIRENET. These ports
are wired in the same manner as a MIB-W (refer to Media Interface Board manual. Figure 2.4-1 shows the
correct screw terminals for both data ports and earth ground.
Each data port has a jumper internal to the MET-1 which determines if the data port is terminated with a 120 Ohm
resistor. The data ports must be terminated for point-to-point operation, and may or may not need to be unterminated
for bus mode operation depending on the node location being tested (refer to Figures 3.3-1 through 3.3-7). The
jumpers are installed at the factory for point-to-point or terminated bus mode operation.
The following steps must be completed to change the termination state of the data ports:
 Remove the two screws from the top and the two screws from the bottom of the MET-1 enclosure (refer
to Figure 2.5-1).
 Remove the MET-1 enclosure. In doing so, be careful to pull the enclosure over the power switch and
the SELECT and START push-buttons.
 To remove termination from port A, move the jumper from position JP1 to position JP2. To add termi-
nation, move the jumper from JP2 to position JP1. To remove termination from port B, move the jumper
from position JP3 to position JP4. To add termination to port B, move the jumper from JP4 to position
JP3 (refer to Figure 2.4-1).
 Position the MET-1 enclosure over the power switch and the SELECT and START push-buttons.
 Replace the two top screws and the two bottom screws of the MET-1 enclosure.

SECTIONTHREE
OPERATION
3.0 MET-1 OPERATION
Twisted pair wire evaluation, existing network point-to-point testing and existing network bus mode testing are
detailed in the following paragraphs (refer to Figure 2.4-1 for wire positions). Earth ground should not be
connected to the MET-1 terminal block at position five when using the power adaptor.
3.1 TWISTED PAIR WIRE EVALUATION TESTING
In order to perform twisted pair wire evaluation testing, the following steps must be accomplished (refer to Figure
3.1-1):
 Two MET-1s are required for twisted pair wire testing when network nodes have not yet been installed.
One MET-1 is used as a transmitting unit and one MET-1 is used as a receiving unit.
 Connect the receiving MET-1 to one end of the wire pair being tested and the transmitting MET-1 to the
other end.
 Turn on both MET-1 POWER switches.
 Press the SELECT button on the transmit MET-1 until the SELECTION window displays the numeral
one and a decimal point (to indicate point-to-point or terminated bus mode) "1." and the TRANSMIT
LED illuminates.
 Press the START button on the transmit MET-1. The transmit MET-1 checks for activity on both ports
and then begins transmitting data. "SEnd" will appear in the display when data is being transmitted.
 The receive MET-1 should be configured so that the SELECTION window displays the numeral one
followed by a decimal point "1." and the RECEIVE LED is illuminated. If not, press the SELECT
button until this is so.
 Press the START button on the receive MET-1. The receive MET-1 analyzes the data on port B and
gives a result. For a detailed description of MET-1 display messages refer to Table 3.1-1.
 If the wire is found to be suitable for use with NOTIFIRENET, program the network nodes at
either end of the wire according to the worst-case evaluation results obtained by the MET-1 and the
NOTIFIRENET manual (refer to Table 1.1-1).
If the evaluated wire is to be used in a bus configuration, it must meet all length and threshold requirements as
specified in the NOTIFIRENET manual (refer to Table 1.1-1). Bus lengths longer than those specified
in NOTIFIRENET manual are not allowed based on MET-1 threshold readings.

3.2 EXISTING NETWORK POINT-TO-POINTTESTING
In order to perform existing network point-to-point twisted pair wire testing the following steps must be accom-
plished (refer to Figures 3.2-1 through 3.2-4):
 A receive MET-1 is required for existing network point-to-point twisted pair wire testing. Nodes already
on the network provide the data to be analyzed. If a MET-1 is to be used as the transmitting unit, refer
to Section 3.1 for testing instructions. If using a transmitting MET-1, repeat Section 3.1 for every wire
pair to be tested.
 Turn on the MET-1 POWER switch.
 Disconnect the NOTIFIRENET network connector from the first node to be evaluated and plug the
connector into the receive MET-1. Fiber optic cable, if present, does not need to be disconnected.
 The receive MET-1 should already be configured so that the SELECTION window shows the numeral
one and a decimal point (to indicate point-to-point or terminated bus mode) "1.", and the RECEIVE
LED is illuminated. If not, press the SELECT button until this is so.
 Press the START button on the receive MET-1. The receive MET-1 analyzes the data on port A and
gives a result, then analyzes the data on port B and gives a result. For a detailed description of MET-1
display messages refer to Table 3.1-1.
 Disconnect the NOTIFIRENET network connector from the MET-1 and reconnect it to the
network node. Configure or evaluate the network node according to the MET-1 test results and the
NOTIFIRENET manual.
 Repeat the procedure for the remaining nodes/repeaters to be tested. This progression is illustrated in
Figures 3.2-1 through 3.2-4 for MIB-W and RPT-W testing, and Figures 3.2-5 through 3.2-7 for MIB-
WF and RPT-F testing.
Due to variations in equipment and environment, it is possible to have variations in readings at either end of the
same pair of wire. If transmitting node malfunction is suspected, evaluate the wire using a transmitting MET-1
according to Section 3.1. If both nodes are fully functional, the worst-case reading should be used for both ends
of the evaluated medium.

3.3 BUS MODE TESTING
In order to test NOTIFIRENETNOTIFIRENET
NOTIFIRENETNOTIFIRENET
NOTIFIRENET bus links, the following steps must be accomplished (refer to
Figures 3.3-1 through 3.3-7):
1. At each node/repeater, disconnect all wiring not associated with the bus link to be tested.
2. Beginning at one end of the bus, select one node/repeater as the first data source location. Place a
transmit MET-1 here, or if a network node is present, configure it to transmit by assigning a non-zero
node address (repeaters should not be used as data sources when evaluating bus links). Set all other node
addresses on the bus to zero.
If a transmit MET-1 is used, press the SELECT button until the SELECTION window displays "1."
(terminated, refer to Section 2.4) and the transmit indicator illuminates. Press the START button. Once
the MET-1 detects no other source of data transmissions, "SEnd" will repeatedly flash on the display
while the MET-1 outputs test data.
3. Disconnect the network connector of each node/repeater (one at a time) and plug it into a receive MET-1.
Terminate the MET-1 in the same way as the node/repeater it replaces. Press the SELECT button until
the SELECTION window displays either "1" (unterminated) or "1." (terminated). Press the START
button. Refer to Table 3.1-1 for a detailed description of test messages. Only the high data threshold
is acceptable for bus links.
4. When each receiving node/repeater location has been tested using the first transmitting location, discon-
nect the MET-1 transmitter, or set the transmitter node address to zero, and repeat steps two and three
for each node/repeater location. Hint: use several MET-1 units (one at each bus node/repeater location)
to avoid constantly moving and reconfiguring the test equipment.
