CAUTION: (Read This First)
This panel has been designed to make it nearly bullet proof to mistakes made
when wiring it to your DAS equipment . Once you have verified that everything
is working as expected, the panel’s 12 VDC backup battery should be the very
last thing to connect. This will ensure that the battery’s 1 amp fuse will be
unlikely to blow due to any wiring errors.
Applicable Models This manual covers the following Model Numbers: 1221-A,
1221-B, 1221-C 1221-A-48, 1221-B-48, 1221-C-48 1221-A-24. 1221-B-24. 1221-C-24
Models 1221-A, 1221-B and 1221-C are all powered by an included 15 VDC power
supply that is wall mounted and connects to any standard 120 VAC outlet.
Models 1221-A-48, 1221-B-48 and 1221-C-48 are powered by a user supplied 48
VDC power supply and backup battery used by the BDA Models 1221-A-24, Model

TOOLS REQUIRED
Standard Voltmeter Tools and hardware for wall mounting INCLUDED TOOLS: The
screw driver for the connector clamps is included in the accessories A trim
pot adjustment tool is included with the accessories for applicable models.
Cable Lengths
This panel is designed to work with standard Cat 5 or Cat 6 cable that
typically has a DC resistance of about 2.5 ohms per 100 ft for a single wire
strand. For all the connections to standard dry relay contacts in the DAS
equipment the length of the cable between the panel and the DAS equipment is
not critical because the current in the loop is only about 1 milliamp. So
cable runs up to 5000 feet or longer can easily be accommodated. This is not
true however for only the Model 1221-A interface connections that are used to
sense the status of the outdoor Donor Antenna. The panel has a circuit in it
that measures the DC resistance of a 50-ohm terminator installed at the
outdoor antenna via a bias-T fitting. If the resistance is too high indicating
an open circuit or too low indicating a short circuit an alarm is triggered.
So the DC resistance of the coax cable, any connectors and surge protectors in
line and the Cat 5 or Cat 6 cabling leading to the panel can be a significant
factor in the overall DC resistance that the panel measures. To null out these
variables there is a trim pot adjustment that must be made when the panel is
first installed, but there is a limit to how much resistance can be nulled.
For this circuit to work well a single twisted pair of cat 5 / cat 6 cable can
be used up to 1000 feet in length. If the cable run is longer than this (for
example 2000 feet) then two twisted pairs should be used in parallel to lower
the cable resistance. Please consult our customer service for additional
advice and information. The DC powered units both draw about 100 milliamps of
current at either 48 VDC or 24 VDC. Please use a wire gauge that supports this
current consumption with minimal DC voltage drop over the length of the cable
run .
Special BDA Configurations and Settings
If your BDA does not conform to the standard alarm relay configuration shown
in Figures 2 or 3, please contact us. We have designed into the panel several
special DIP switch settings that can accommodate almost any non-standard alarm
set up. For example the CommScope NODE A requires some special settings to
deal with issues when power is disconnected. Please contact us for more
information.

Model 1221-A, 1221-B and 1221-C Independent DAS Annunciator Panel
Included Items:
QTY Description 1 Main Alarm Panel 3 16 pin cable connector 1 8 pin cable connector 1 6 pin DC Power connector 1 Screw Driver for mating wires to connectors 1 9 Ahr 12 vdc SLA backup battery 1 Trim pot adjustment tool (in applicable models) 1 Installation Manual 10 10 k Ohm 0.25 watt end-of -line resistor 1 15 VDC wall mount power supply (in applicable models) 1 Spare 1 amp battery fuse 1 10 pin connector
This panel is designed to meet the requirements of NFPA -72 (versions 2010,
2013 and 2016), and the 2016 version of NFPA-1221.
It consists of several component sections that enable its use with many
different types of BDA’s and backup power supplies / UPS. It also has the
capability to support DAS installations that have multiple amplifiers and
donor antennas. Physically the panel modules consist of two printed circuit
boards: the LED Board which is mounted on the back side of the door and the
Mother Board that is mounted inside the main body of the enclosure. There is a
shelf / cavity that holds the included 9 Ahr 12 vdc SLA emergency backup
battery. A 15 VDC power supply is also included in applicable models that can
be connected to any 120 VAC electrical outlet. Models that are powered by 48
VDC or 24 VDC do not include this power supply. Figure 1 shows the main
components. Figure 12 shows the other supplied items.
The main system sections are as follows for the standard models 1221-A and
1221-B:
1. HIGH Brightness 3-color (Red, Green, Blue) LED Annunciator Displays · Main
AC power Loss · BDA / Amplifier Alarm · Summary System Alarm · Antenna Failure
· DAS Battery Charger Failure · DAS Battery Capacity Low (less than 30%)
The panel also provides individual Blue LED indications if there is a
communications error (open, disconnected or shorted cable between the panel
and the DAS equipment).
2. Communications Integrity Sensors For each alarm relay from the BDA or
backup power supply a sensor is provided that detects if the cables connected
to these devices are open or disconnected. A set of dry relay Form-C contacts
are also provided to optionally communicate this problem to the main fire
alarm panel (MFAP).
3. FORM- C Dry Relay Contacts to mate with common Fire Alarm Panels (See
Figure 5) These alarm contacts are rated at 1 amp and include provisions for
easily installing End-of-Line Resistors (EOLR) inside the panel. These relays
utilize the same signaling format as smoke detectors. So in the event of an
alarm or panel failure the relays will close shorting the end-of-line
resistor.
4. ANTENNA Failure (Model 1221-A See Figure 6) Some BDA’s lack the capability
to detect problems with the donor antenna or its lead-in cable. This panel
includes the internal circuitry to provide this functionality if the BDA does
not provide it. It mates with user supplied bias T fittings to sense common
donor antenna feed problems.

5. DAS Backup Battery Charger Failure (Model 1221-A) If the DAS backup battery charger or UPS does not have a failure sensor, the panel can provide alternative functionality.
6. DAS Backup Battery Capacity less than 30% (Model 1221-A) If the backup power supply or UPS does not have this alarm capability, the panel can provide alternative capability.
7. Backup 24 Hour Panel Power The panel is powered via an external wall mounted 15 VDC power supply or the external 48 VDC or 24 VDC power supply that provides emergency power for the BDA. In the event of AC power loss or loss of 48/24 VDC, the panel will continue normal operation for at least 24 hours. The panel’s internal backup battery has a lifetime of 4-5 years. Best practices call for replacement on an annual basis. The panel is designed for a backup battery with these maximum dimensions: 5.96″ L x 2.58″ W x 3.65″ H or smaller. The replacement battery is available from Amstron (Model AP-1280 F2).
The panel’s battery also has a method of reporting its failure or its need for replacement to the Main Fire Alarm Panel. This feature can be turned OFF or ON. The default mode for this is OFF. (DIP switch SW4-10 ON)
8. NEMA-4 rated wall mounted enclosure The fire codes require that this panel meet the NEMA-4 water resistant requirements. It has four thermoplastic knockouts on the bottom of the panel that provide four openings for standard ½” and ¾” EMT conduit fittings. If any of the knockouts are not removed, they should be sealed in place with RTV or a similar sealant to maintain the enclosure’s NEMA-4 rating.
9. Test Features A “push to test” button is provided that will illuminate each of the 3 color LEDs (red , green and blue) for a few seconds in each color. During this test the alarm relays to the main fire alarm panel (MFAP) are also actuated. To disable this push button see page 19. To statically test the alarm relays there are internal DIP switch settings that will simulate alarms or normal status for the these relays. (see Table 1). For the Model 1221-C series the LEDS are Amber, Green and Blue.

Mating with DAS Equipment
Figure 2 shows the standard method of mating this panel with a BDA and UPS.
The standard method is the same as that used to connect to most Fire Alarm
Panels where an end- of- line- resistor (EOLR) is used to sense the alarm
status and detect if the cables are open, disconnected or shorted. Most BDA
and UPS units are provided with Form- C dry relay contacts that can be
connected so if there is an alarm or power failure the relay will close
providing a short across the end-of-line resistor. For this panel the EOLR is
10 k Ohms, These are provided with the panel accessories for connection at the
DAS equipment.
Some BDA or UPS suppliers do not provide Form-C dry relay alarm contacts (See
Figure 3). Instead they use Form-A contacts which open when there is an alarm.
In this case the panel can be programmed to accommodate this mode by closing
the appropriate DIP switch as shown in Table 1 in the APPENDIX.
Figure 4 shows how to wire to the panel if multiple BDA’s or UPS units are
utilized in the system. In this configuration, the EOLR is located at the last
unit in the daisy chain.
In the event it is not possible to install the 10k Ohm EOLR at the DAS
equipment, these can be simulated by closing the appropriate DIP switch as
shown in Table 1. This method can also be utilized for testing to simulate an
‘OK’ status input when the DAS equipment is not connected or if one or some of
the DAS alarm inputs are not used.
Connections to Main Fire Alarm Panel
Figure 5 shows the output cable connections from the internal relays to the
Main Fire Alarm Panel (MFAP). NOTE: Connectors J2 and J7 on the LED PC board
are designed to be directly wired to the MFAP. Connectors J4 and J3 on the LED
PC Board are internally connected pin-for-pin to the relays and are intended
to hold and connect the end-of-line resistors specified by the MFAP supplier
to the relay contacts (See Figure 20). Figure 5 shows the relays in their “not
energized” power off (Alarm) positions. The plugs for these connectors are
mated with their headers on the PC boards. To connect them to external wiring
a miniature screw driver is included that is used to tighten the wire clamp on
each pin. (See Figure 17) The wire clamps will accommodate wire sizes up to 16
AWG in diameter and as small as 26 AWG. Note that these connectors are NOT
keyed, so careful attention must be paid to the pin numbers that are marked on
the PC board when mating the connector. You also must check that the connector
is not offset to insure that all of the appropriate pins of the header are
mated with the plug. This is an easy error to make when mating this type of
connector.
The relays are shown connected to a master fire panel that uses the normal
conventional alarm configuration (i.e. when the relays signal an alarm, they
are closed causing the EOLR to be shorted). In the unlikely event you are
connecting to a panel that uses the opposite convention, the unused contacts
on the output relays are also available to connect to and conform to this non-
standard convention.
Alarm relays are provided for loss of AC POWER, AMPLIFIER malfunction, DONOR
ANTENNA malfunction, DAS Backup battery CHARGER failure, and DAS BATTERY
CAPACITY low. Optional alarm relays are provided to signal a COMMUNICATIONS
FAULT with the DAS equipment (open, severed or disconnected cable between the
annunciator panel and DAS equipment) and an optional SYSTEM summary alarm that
is triggered when any of the other alarms are active. This relay can also be
connected to an audible external alarm instead of the fire alarm panel.
DIP Switch Settings
DIP switches are used to program the functionality of the panel. Unless we
have advised you otherwise, the panel is shipped with the standard default
factory settings shown in the table on the next page. Details regarding the
function of each switch are shown in the APPENDIX.

Antenna Failure Sense (Models 1221-A and 1221-C) If the BDA in your system
does not have the capability to test antenna and lead-in cable failures, this
panel can provide an alternative method for detecting most common problems
(cable shorted or disconnected). It should be noted that up until the release
of the 2016 version of the NFPA1221 specifications there was some ambiguity in
the codes relative to this requirement relating to the need to test all the
antennas in the system (both indoor and outdoor) or if the code required
addressing only the outdoor donor antenna. In the 2016 version, the
requirement is clearly stated for the outdoor donor antenna. Detecting
problems with the indoor antennas is optional. The method used involves
injecting a DC voltage (10 VDC) onto the lead-in cable at the input to the BDA
using a user supplied bias-T. Another bias-T (user supplied) is used outdoors
at the antenna to provide a 50 Ohm DC load (See Figure 6). A typical bias-T
rated for 1 watt of RF power can be purchased from Mini-Circuits (Part #
ZNBT-60-1W+) High power rated units can also be purchased from Mini-Circuits
If the cable is shorted or open the detector will sense this and trigger an
alarm. If multiple antennas are to be sensed, connect them as shown in Figure
7. Since cable and connector DC resistance may vary in each installation there
is a trim pot adjustment provided to null these variables out. The procedure
is as follows.
· On the Mother Board set the DIP switches different from the default settings
as follows: SW1-3 ON SW3-6 OFF SW3-7 ON (See page 38 for photos of these
switch settings)
· Connect a DC voltmeter to the test points labeled ANT and GROUND on the LED
Board · Adjust the trim pot labeled ANT TRIM (R35) on the LED board until the
DC voltage reads
5.0 VDC. Note: This is a 20 turn potentiometer end-to-end. The voltage will
vary from a maximum of 10 VDC to zero as it is adjusted. Turning the pot
clockwise will increase the voltage. This voltage has an acceptable window of
±1 VDC, but you should try to adjust it as close to 5.0 VDC as possible This
method obviously does not detect all antenna problems such as the antenna
being blown down in a storm or a new building being constructed between the
donor antenna and the public safety repeater, but it will detect common faults
such as a short circuit, a severed cable or a loose connector and it will pass
the test that most inspectors employ by simply disconnecting the cable
connected to the outdoor donor antenna.

DAS Secondary Power Backup Battery Capacity Test (Model 1221-A and 1221-C)
The code requires monitoring the DAS backup secondary battery to determine when it has less than 30 % capacity left under normal full load emergency backup conditions (no AC power). If the UPS in the system does not have the capability to do this, the panel provides an alternative technique. (see Figure 8 which shows appropriate connections to the external DAS backup power battery). This method measures the battery voltage and when it reaches a predetermined threshold an alarm is triggered. To enable this mode connect the DAS battery as shown in Figure 8 and set the DIP switches on the Mother Board as follows: ( see page 39 for photos of these switch settings)
SW1-10 ON SW1-5 ON
SW3-10 OFF
Battery suppliers provide specifications that show how the nominal battery voltage varies as a
function of load current and capacity. Different types of batteries from different vendors will have
varying specifications. To accommodate this variability a trim pot adjustment is provided on the LED
PC board. The table below shows the appropriate DIP switch settings for 48, 24 and 12 VDC
systems. Once these switches are set, connect a DC voltmeter to the test points labeled “Battery
Low Threshold Test Point” and Ground. Adjust the 20-turn trim pot labeled “DAS BAT Threshold
Adjust (R41)” to set the 30% threshold to the require voltage. NOTE: The test point provides the threshold voltage scaled down by a factor of 10. For example, a threshold trigger point of
45 VDC will read 4.50 VDC on your voltmeter.

DAS Battery Charger Failure (Model 1221-A and 1221-C)
(On Mother Board set SW3-8 OFF, SW3-9 ON and SW1-4 ON
The code requires monitoring the charger used to keep the DAS secondary power battery at full charge in case of AC Power failure. If the UPS in the system does not have the capability to do this, the panel provides an alternative technique. This method measures the battery voltage and when it reaches a predetermined voltage threshold, an alarm is triggered. To enable this mode set DIP Switch SW3-8 on the Mother board to OFF, SW3-9 on the Mother board to the ON position and SW1-4 to ON. Different types of batteries and chargers from different vendors will have varying performance. To accommodate this variability a trim pot adjustment is provided on the LED PC board. The table above shows the appropriate DIP switch settings for 48, 24 and 12 VDC systems. Once these switches are set, connect a DC voltmeter to the test points labeled “Charger Bad Threshold” and Ground. Adjust the 20-turn trim pot labeled “DAS Charger Threshold Adjust” to set the desired threshold to the require voltage. NOTE: The test point provides the threshold voltage scaled down by a factor of 10. For example, a threshold trigger point of 52 VDC will read 5.20 VDC on your voltmeter.
To determine the appropriate threshold, you should run a test to measure the nominal battery voltage when the charger is on vs when the charger is turned off or disconnected. The battery voltage should be lower when the charger is off and the battery is under load.

AC Power Loss Alarm (Model 1221-A , Model 1221-B or 1221-C) There are two
methods that can be used to detect loss of AC Power:
1. Connect the panel to an external DAS device (BDA or UPS) that provides
Form-C relay contacts to signal an alarm. Figure 2 shows these connections.
This is the default mode and the panel is shipped with the DIP switches set to
enable this mode.
2. Use the loss of AC power to the panel’s 15 VDC power supply to sense AC
power loss. To enable this mode, on the Mother Board set DIP switch SW1-1 ON
and SW1-6 to ON
Model 1221-C or Model 1221-C-48 or Model 1221-C-24
These versions of the panel operate exactly like the Models 1221-A,1221-A-48
and 1221-C except that the colors of the alarm LED indicators on the panel are
different to conform to a rarely used color standard that some jurisdictions
occasionally specify.
The table below shows the color coding. For an alarm condition, the LED will
turn AMBER (yellow). If there is no alarm, the LED will be OFF (except the AC
POWER indicator that will turn GREEN).
If there is a communications fault (open, shorted to ground or disconnected cable) between the DAS equipment and the panel, the LED will turn BLUE (except the SYSTEM LED that will be AMBER)

Panel Power Supply and Backup Battery Figure 11 shows how the 15 VDC power
supply is attached and the panel’s backup battery. Connect the battery last
after everything else is working as expected. This minimizes the chance that
an inadvertent wiring error would cause the battery’s 1 amp fuse to blow.
There is an option to monitor the status of this battery and notify the
building’s main fire alarm panel if it is low or needs replacement. This can
be done by setting DIP SW4-10 on the LED board to the OFF position. If the
battery needs to be replaced, the SYSTEM LED will flash on and off once per
second and the SYSTEM alarm relay will signal an alarm to the building’s main
fire alarm panel. For models that run on 48 VDC or 24 VDC, Figure 11B shows
how the power connections are configured.
End to End Testing. DIP switch settings on the Mother board are provided to
simulate various alarm conditions: · DIP switch SW1-7 (Normally OFF, when ON
all LEDs will be Red and all relay signals to the main
fire alarm panel will be forced to the alarm state except the Communications
Fault Alarm. · DIP switch SW1-8 (Normally OFF, when ON all LEDs will be Green
and all relay signals to the
main fire alarm panel will be forced to the normal non-alarm state. DIP switch
SW1-9 (Normally OFF, when ON all LEDs except the SYSTEM LED will be blue . The
SYSTEM LED will be Red and the Communications fault and System relay signals
to the main fire alarm panel will be forced to the alarm state. All other
relay signals to the main fire alarm panel will be in the normal non-alarm
state.
Disabling the “PUSH TO TEST” Button If the panel is located in a public space
it is advisable to disable the “PUSH TO TEST” button on the front panel once
the unit is installed and tested.. Otherwise the button could be actuated by
unauthorized persons and trigger a false alarm to the building’s Master Fire
Alarm. To do this, set DIP switch SW4-7 on the LED BOARD to the ON position.
Normally it is OFF.

Test Points (TP)
Test Points (TP) are provided on the LED board to use for troubleshooting and
system setup (see Figure 18). These TPs are designed to mate with standard
voltmeter probes. Each TP is isolated from the main circuits via a 10k
resistor so if a TP is inadvertently shorted, no damage will result. The table
below shows the nominal DC signals that can be measured at each TP.
