1 OPERATION
1.1 GENERAL
The B1225E Alarm Expander Unit is an 8-input, 4-output board which expands the number
of alarm inputs and relay outputs. The expander boards connect to the B1225 ARU and to
each other via a serial cable. All of the programmable features of the B1225E are controlled
by the B1225 master, such as debounce time, relay on/off codes, DTMF on/off codes, input
polarity and voice messages.
The maximum number of expander boards which may be added to one B1225 ARU is seven.
Each expander has a binary address controlled by a DIPswitch on the board. The four relay
contacts available for remote control respond to DTMF codes received over the radio by the
master (B1225 ARU).
1.2 ALARM TRANSMISSION
When an alarm goes into an “active” state or a timer expires, the B1225 ARU goes through
the transmission sequence described in the B1225 operator’s manual: transmitting the master
site ID, master alarms, expander ID, and alarm conditions. The expander(s) will send out the
DTMF-on code and voice messages until the alarm returns to normal;then the DTMF-off
code is sent. A different DTMF code can be programmed for each input, providing eight
DTMF on and eight DTMF off sequences in total.
1.3 RELAY CONTROL
The four relay outputs are controlled through the master. By programming the “Relay on
code” and “Relay off code”, as shown in the programming section, the B1225E’s relays can
be remotely controlled.
When the master receives a Relay On (or Off) code over the radio system, it will turn the
corresponding expander relay on (or off) and transmit over the radio system the relay number and new condition.
1.4 MEMORY STORAGE
The B1225E holds all of its operating parameters in battery backed up RAM. Internally, all
operating parameters are stored in two separate memory locations: a working space and a
redundant storage space. Both memory spaces are protected by a security code, ensuring
that all information is valid. Should one piece of data become corrupt in either of the data
spaces, it is automatically replaced with the valid data from the other location.
If a major error occurs and both the working and the storage data spaces have been corrupted, the B1225E will signal the master to reset all parameters concerning the expander to
default values. At this point the announcement “(SITE ID) - PROGRAM x CODE ERROR”
is made (x representing the number of the expander with the major errors).
Security codes and the RAM redundancy affect only the operating parameters and are not
used for the stored site identifier or alarm voices.

2 INSTALLATION
The B1225E should be mounted in a clean, dry area suitable for electronic equipment. All
connections, except for the signaling cables, are made to the compression screw terminals
TB1 and TB2. TB1 handles all of the inputs and power, while TB2 contains the relay contacts.
An 11 to 16 volt, negative ground power supply capable of delivering 200 mA is required. If
the AC supply/battery back-up option is used, connect the red wire to TB1-1 and the black
wire to TB1-9. The ground terminal is also used in a common reference for the alarm inputs.
The signaling cables between the master and the expanders connect from SERIAL OUT on
one board to SERIAL IN on the next. This provides communication between the master and
the expanders.
Refer to diagram Figure 1 for wiring instructions.
Figure 1 Installation Wiring
POWER TB1-9 Neg. TB1-10 position
The B1225E requires 11 to 16 VDC, negative ground to operate. Typical operating current
is 100 mA, but may increase if all relays or LEDs are on. Connect power to the board only
after all other connections have been made.

ALARM INPUTS TB1-1 thru TB1-8
The external dry relay contacts, representing the alarms, are connected to terminals 1 to 8 inclusive. These optically coupled inputs sense alarm activity by either a closure to ground or
an open circuit. Programming options select either normally open (NO) or normally closed
(NC) alarm contacts. The alarm ground must be the same as the power ground. Do not apply any voltage source to the input terminals. Active current on each input is 100 mA.
RELAY OUTPUTS TB2
Four form C relay contacts are available on TB2. Table 1 shows the connections available at
each pin. The relays are controlled by receiving DTMF digits from the radio system
(through the master) that correspond to its internally programmed parameters. Refer to the
programming section for further details.

TABLE 1 RELAY CONNECTIONS
SERIAL IN / SERIAL OUT PORTS P3, P4
Connections from the master to the expander and between expanders are made to P3 and P4
using a shielded single cable conductor. This connection allows data to be transferred between the master and the expanders.
ALWAYS power up both the expander and ARU together AFTER this communication cable
has been connected. Failure to do so could cause damage to one or both units.

EXPANDER DIPSWITCH SETTINGS
Expander addressing and the LEDS are controlled by DIPswitch SW1.
SW1-1 to SW1-3 are used for expander addressing. Expanders must be numbered sequentially from 1 to 7. The address is configured as follows (X indicates OFF) :
SWITCH
1 2 3 4 5 6
X
ADDRESS
1
X
2
X X

If an expander address is changed, the unit must have power removed and then reapplied in
order for the master to recognize its new address. All the expander’s programmed parameters, aside from the voice messages, will reset to the default parameters when its address is
changed and will have to be re-programmed. When the expander is powered back up, “Program code error” will be announced, indicating that the expander was reset. Only the expander with the changed address will reset. The master and the rest of the expanders will
retain their programmed parameters.
SW1-8 is used to turn the LEDs on and off. SW1-4, SW1-5, SW1-6,and SW1-7 are not
used.

3 PROGRAMMING
3.1 GENERAL
The B1225E is programmed by the B1225 master unit. The features which are programmable in the B1225E are the voice messages, polarity of inputs , debounce time, DTMF on/off
codes and the relay on/off codes.
The B1225E will be shipped with either the default parameters or the factory testing codes
and can be programmed to each operator’s individual requirements.
Program data is stored in a battery protected RAM with a 30 day retention period. After 30
days without external power, the ARU may lose its programmed data and revert to the default state. The contents of the RAM may be are periodically altered. An error detected at
any RAM address will result in default operation. The default conditions used are shown at
the end of this section.
Before any expanders can be programmed, the B1225 ARU must be configured for the total
number of expanders connected (program code 10). Refer to the B1225 Operations Manual
to change this parameter.
If an expander number is not configured in the master B1225, or an expander is not present
that has a programmed address, attempts to program the expander will generate the message
“ERROR, ENTER PROGRAM CODE”.
3.2 PROGRAMMING SEQUENCE
If the B1225E has never been programmed or has lost its memory, the site identifier and all
alarm messages will be simply noise. This noise may be very loud, depending on hardware
adjustments. USE CAUTION when listening to the programming parameters, especially initially, as loud noise may be given as the stored voice.
When you connect your Touch Tone telephone into the program port of the B1225 ARU and
take it off hook, the “Enter program code” message will be announced. At this point, the
master and expanders can be programmed. To begin programming expander number X, enter: # X program code ÝÝ.
Example: You are at the main menu and you want to change the debounce times
(program code 5) on the first expander (address 1) to 3 seconds.

An un-programmed voice message will be heard as a loud static noise. DO NOT hold the
telephone directly to your ear when programming these messages for the first time.

expander may have a different time. The input must remain active for this period of time in
order for it to be considered a change of state.
Example: The debounce time for expander 2 is to be set at 3 seconds.
