2.0 APPLICATION
The 2412, 2414, and 2418 panels are suitable for small to medium size buildings, requiring from two to
eight Initiating Device Circuits (IDCs), and two Indicating Appliance Circuits (IACs).
2.1 Fire Alarm System Limitations
Fire Alarm Systems provide the occupants of a facility with early warning of smoke and fire conditions. Fire
alarm systems use a variety of components to meet the requirements of each installation. The fire alarm
panel, automatic and manual detection devices, alarm annunciators, and the installation wiring are all
factors in a reliable system. To maintain proper operation, fire codes require, and this manufacturer
recommends preventive maintenance and testing on a routine basis by qualified personnel.
3.0 THEORY OF OPERATION
3.1 Initiating Device Circuits (IDCs)
The supervised IDCs operate with compatible smoke detectors (refer to Appendix) and normally-open
alarm initiating devices. An IDC may be programmed as an Alarm, Waterflow/Supervisory, or Supervisory
zone. Alarm zones may have verified or non-verified operation. Waterflow/Supervisory zones programmed
with or without a 15 second retard period, also support a single supervisory input device with a
1.1KWseries resistor. IDC circuits may take one of four operating states: Normal, Trouble, Alert, or Alarm.
Table 3.1 defines the states for the various IDC zone types.

WARNING! Do NOT put contact devices on Low Impedance Verified Circuits.
An active IDC defined as an Alarm or Waterflow Zone may be identified by a steady red zone LED. Active
IDCs defined as supervisory zones may be identified by a rapid flashing amber zone LED.

6
When an IDC is programmed as a waterflow zone, the IACs DO NOT respond to the ALARM SILENCE
switch or automatic alarm silence until the waterflow device is no longer active. Both an alarm initiating
device and a supervisory contact may co-exist on the same circuit by putting a 1.1KΩin series with the
supervisory contact. When the waterflow with retard option is programmed, a special algorithm samples
the circuit repeatedly. If 66% of the samples taken in any 15 second period indicate a waterflow (shorted)
condition, the circuit activates a waterflow alarm.
When an IDC is programmed as a verified zone and a smoke alarm is detected, the panel enters the
Alarm Verification state. A twenty five second sequence in which the detector is reset, delayed, and
restarted is initiated, as shown in Figure 3.1. If auxiliary power is programmed as resettable, it is de-
energized for the reset period. Following the reset-delay-restart sequence, a 60 second verification
window is opened. If the verifying zone should go into the Alert, Alarm, or Trouble conditions within the 60
second window as shown in Figure 3.2, the panel enters the alarm mode. If any other IDC on the panel
goes into the alert or alarm state during the verification period, the panel immediately enters the alarm
mode. Dry contact alarm initiating devices may be combined with High Impedance 2-wire smoke detectors
on verified zones. The closing of a normally open dry contact alarm initiating device generates an Alarm
state immediately, and the panel enters the alarm mode.
Initiating Device Circuit, Class A (Style D) Operation
To convert a Class B (Style B) IDC zone to a Class A (Style D) IDC zone, install a 2400-BPA Class A
(Style D/Z) Converter on the base panel, or a 2400-IDCA Class A (Style D) Converter on the Two Zone
IDC Module. The converters provides an alternate path to the zone module for all Initiating Devices in the
event of a single wire break in an IDC.
NOTE
2- Wire Relay Bases are NOT supported on Initiating Device Circuits (IDCs).

3.2 Indicating Appliance Circuits (IACs)
Two supervised Indicating Appliance Circuits (IACs) operate using compatible 24 VDC (nominal) polarized
signaling appliances. Each circuit is rated at nominal 24 VDC @ 2.5 Amps, with a total of 4.0 Amps
available for both circuits. An IAC may be programmed as either silenceable or non-silenceable. Signal
rate selection is independently programmable for each IAC as shown in Figure 3.3. Refer to the Appendix
for compatible Indicating Appliances.
IACs generate a trouble indication (slow flashing LED) when field wiring is open or shorted. In an open
fault condition, the panel will attempt to energize the signal appliances (i.e., all appliances up to the circuit
break will operate). An IAC with shorted field wiring will NOT operate in the event of an alarm. If an IAC
develops a short during an alarm, the IAC will automatically shut off and continuously monitor the field
wiring. When the fault is cleared, the IAC will re-energize. These actions protect the power supply and
other panel components from damage caused by the short circuit.
Indicating Appliance Circuit, Class A (Style Z) Operation
To convert Class B IAC zones to Class A (Style Z) IAC zones, install a 2400-BPA Class A (Style D/Z)
Converter Module on the base panel. The converter provides alternate paths to the base panel for both
Indicating Appliance Circuits in the event of a single wire break in an IAC.

4.4 Installation Instructions
Mounting the Backbox
Install backbox per drawings Control Panel INSTALLATION 1 and Control Panel INSTALLATION 2. If a
2400- BATBOX Battery Cabinet is required, refer to the CONTROL PANEL APPLICATIONS 2 drawing for
information.
Utility or Primary Power Circuit
NOTE
Install primary power conduit on lower left side or left bottom of backbox.
The panel requires a dedicated 120 VAC, 15A, 50/60 Hz branch circuit. Label the circuit breaker "Fire
Alarm Control Panel." Within the fire alarm enclosure, route wire away from power limited circuit wiring.
WARNING
Do NOT apply power at this time.
System Control Wiring
1. Refer to the drawings at the end of this manual for circuit wiring diagrams and wire charts showing
maximum wire runs and loading. Install system wiring using the wire type and gauge per the Authority
Having Jurisdiction. Locate field wiring conduit on the upper sides and top of the backbox. At the
panel, leave approximately 5’ (1.5 m) of wire available for dressing and termination. Pair and
label wires according to zone and function. Do not mix power limited and non-power limited wiring in
the same conduit.
2. Do not remove the factory installed test resistors from the panel at this time. The test resistors are
used for panel testing in the next steps. Refer to the drawings provided with each initiating and
signaling device for installation details. Install End-Of-Line resistors at the end of Class B circuits.
3. Use an ohm meter to check circuit continuity and verify that the wiring is free of shorts and ground
faults, as follows:
Class B (Style B) IDC meter readings should show 4.7KΩ(EOL Resistor) between circuit pairs.
Each wire should show an open to ground.
Class A (Style D) IDC meter readings should show a short between each set of outgoing and
incoming wires, and an open between each side of the circuit.
Class B (Style Y) IAC meter readings should show 4.7KΩ(EOL Resistor) between circuit pair in
one direction and a short (polarized signals conducting) with the meter leads reversed. Each wire
should show open to ground.
Class A (Style Z) IAC meter readings should show a short between each set of outgoing and
incoming wires. Readings should show an open in one direction and a short (polarized signals
conducting) with the meter leads reversed between each side of the circuit.

Base Panel Assembly
CAUTION
The electronic components used in this system are sensitive to static electricity. Always
discharge any static buildup on your body by touching the panel enclosure before
handling any electronic components.
WARNING
The System Power Supply (the printed circuit board on the back of the Base Panel
Assembly) handles 170 VDC when powered. DO NOT handle this board with power on.
1. Remove the Base Panel Assembly from its anti-static carton.
2. Remove and place the anti-static foam packing on a flat work area.
3. Place the Base Panel Assembly Display face down on the foam packing. Leave the factory end-of-line
resistors in place on the base panel and expansion modules until making final connections.
Option Module Installation
If your system requires no optional expansion modules, skip to the section entitled Base Panel Assembly
Installation.
1. Refer to the CONTROL PANEL INSTALLATION 1 and CONTROL PANEL INSTALLATION 2 drawings.
2. Remove the Power Supply from the Base Panel Assembly to allow for first module installation.
3. Install Expansion Modules on the Base Panel Assembly from left to right (front view) starting with IDC
Modules, Remote Annunciator Driver Modules, then the Relay/City-Tie Modules. Before installing
the ADM & ADS Annunciator Driver Modules, verify that all jumpers are installed. Before
installing the RCT Relay/City-Tie Modules, verify that jumpers 1 & 2 are installed. Refer to
RELAY/CITY-TIE & REMOTE ANNUNCIATOR drawings for additional jumper information.
NOTE
The Dialer Module MUST be installed in position number 3 or higher to prevent
mechanical interference with other system components.
Do NOT connect the Dialer Module’s ribbon cable to the adjacent module until the rest of the
system has been installed and tested.
4. Insert all ribbon connectors (except the Dialer Module) into the adjacent socket, and re-install the
Power Supply on the back of the Base Panel Assembly. The Dialer Module will be connected later.
5. For Class A (Style D/Z) circuits, install the 2400-BPA Class A Converter modules on the back of the
Base Panel Board and 2400-IDCA on the back of the IDC Expansion Modules. Refer to CONTROL
PANEL INSTALLATION 1, CONTROL PANEL INSTALLATION 2, and INITIATING DEVICE CIRCUIT
drawings.
Base Panel Assembly Installation

12
1. Refer to the CONTROL PANEL INSTALLATION 1 or CONTROL PANEL INSTALLATION 2 drawings. If a
2400-BATBOX Battery Cabinet is required, refer to the CONTROL PANEL APPLICATIONS 2 drawing
for information.
2. Lift wiring up and away from the backbox, and install the Base Panel Assembly using the four quick
fasteners. Do not connect control circuit wiring at this time.
3. Install the panel door and make the ground connection (green wire) from the power supply to the
middle door mounting stud.
WARNING
Batteries can deliver extremely high currents. To prevent serious burns caused by short
circuiting the battery, remove all jewelry before handling.
4. Place the batteries in the lower right area of the backbox. If using the external battery cabinet, put the
batteries in the battery cabinet.
5. Interconnect the cells per the CONTROL PANEL INSTALLATION 1 or CONTROL PANEL INSTALLATION
2drawings. If a Battery Cabinet is being used, refer to the CONTROL PANEL APPLICATIONS 2
drawing for information. Connect panel battery leads at this time. Observe polarity: Red =
positive (+); Black = negative (-)
CAUTION
Observe polarity. Red is positive(+), Black is negative(-). A non-replaceable fuse
protects the system from damage caused by a reversed battery connection.
Power Up
1. Verify that all factory installed end-of-line resistors are still in place, all -ADM & -ADS module jumpers
are all installed, and -RCT module jumpers 1 & 2 are installed.
2. Connect primary power wires: Line, Neutral, and Ground to the input terminals of the power supply.
3. Energize AC power to the system. When you first apply power to the system it will follow an
initialization procedure. This procedure programs all connected IDCs as non-verified alarm inputs and
identifies the configuration of all output modules (it can take up to 15 seconds). You will see zone
LEDs turning on and off in sequence and communication LEDs (lower edge of expansion module
boards) flashing. Allow the system to complete this procedure before touching any controls. At the end
of the process, all LEDs except the Power On LED should be off. If the system trouble LED is on and
the trouble signal is sounding, refer to the trouble shooting procedures in this manual. If module LEDs
remain on steady, refer to the Programming section for additional information.
4 Install the lower protective plastic barrier over the high voltage terminals. Make sure to install this
cover strip. It protects you from the high voltage input terminals and traces on the power
supply printed circuit board.
Programming the Panel
1. Remove the Common Control insert card, reverse it, and then return it to its panel location. The
Common Control switches are now labeled for programming functions.
2. Refer to Table 5.1 for panel default operations and the PANEL PROGRAMMING drawing for
programming information. For Dialer Module programming, refer to the DIALER MODULE drawing
