NOTICE!
To help prevent damage from electrostatic charges or
other transient electrical surges, connect the system
to earth ground before making other connections.
1. Use 14 AWG (1.6 mm) to 16 AWG (1.3 mm) wire for the
connection. Do not use telephone or electrical ground.
2. Use a grounding rod or a cold water pipe.
3. Install the wire as close as possible to the grounding
device.
NOTICE!
The module reads the address switch setting only
during power up. Cycle the power to the module in
order for the new setting.
The control panel uses the address for communications. Use
the control panel configuration to set the address switches. If
multiple modules are on the same system, each module must
have a unique address.
This module adds a maximum of 2A of 12 VDC power for Fire
and Burglar standby power applications.

Table 4.1: Current rating chart for standby calculations
Battery Size (AH’s) for Commercial Fire Applications:
To select the size, compare the current calculations from
Table 5.1 against the highest current available for the
standby hours required. If the current from “Total A” or
“Total B” is bigger than the highest value in that column,
then use a second B520 to split the current load.
Battery Size (AH’s) for Burglar Applications:
To select the size, compare the current calculations from
Table 5.1 against the highest current available for the
standby hours required. If the current from “Total A” is
bigger than the highest value in that column, or the current
from “Table B” is bigger than 4A, then use a second B520 to
split the current load.
* (digital section = 22 mA) + (Qty of relays x 16 mA) = total current. (Add 16 mA for each relay being used).
** Use 110 mA + reader current. Do not exceed 260 mA.

7 | Troubleshooting
When the tamper switch is activated (closed to open), the
heartbeat LED stays OFF for 3 seconds, then shows the
firmware version. The LED pulses the major, minor, and
micro digits of the version, with a 1 second pause after each
digit.
Flashing patterns start after the tamper is open (short is
removed). The following is an example: The version 1.4.3
would be shown as LED flashes:
[3 second pause] *___****___*** [3 second pause, then
normal operation]
• With a tamper switch, push and release the switch with
the enclosure door open.
• Without a tamper switch, briefly short the tamper pins.
Refer to the following illustration for an example of flash
patterns.

Flash pattern Corrective action
Heartbeat – 3 quick
flashes every 1 sec
1. Check wiring connection.
2. Check Control panel
programming.
3. Check address selections.

1. Measure the voltage at the
terminals.
2. If the voltage is above 13.3
VDC, and the battery is a fully
charged, the module goes back
to normal state after some of
the energy is removed from the
battery.
3. If the voltage is below 13.3 VDC,
the module may be damaged.
AC Flashing Measure the AC voltage before
and after the transformer. If there
is voltage before and none after,
replace the transformer.
Use Remote Programming Software to program the control
panel to work with the module. For programming parameter
descriptions, options, and defaults using RPS, refer to RPS Help.
