SPECTRA SERIES 9

2.3 AC POWER
Do not use any switch-controlled outlets to power the transformer. Connect the transformer as shown in Figure 2.1
on page 7. Use Table 1 to determine the required transformer.
2.4 BACKUP BATTERY
In order to provide power during a power loss, connect a 12VDC 4Ah rechargeable acid/lead or gel cell backup
battery as shown in Figure 2.1 on page 7. Use a 7Ah battery to comply with UL fire requirements. Connect the
backup battery after applying AC power. When installing verify proper polarity as reversed connections will blow the
battery fuse. Also, refer to Battery Charge Current on page 43.

2.4.1 BATTERY TEST

If the battery is disconnected or if the battery fuse is blown, a No/Low Battery failure will appear in the
keypads’ Trouble Display (see page50). This trouble will also appear if the battery’s capacity is too low or
if the voltage drops to 10.5 volts or lower while the control panel is running on the backup battery. At 8.5
volts or lower, the panel shuts down and all outputs close.
2.5 AUXILIARY POWER TERMINALS
The auxiliary power supply terminals can be used to power motion detectors, keypads and other modules or
accessories in the security system. A fuseless circuit protects the power supply against current overload and
automatically shuts down if the current exceeds 1.1A. If this occurs, the Maximum Auxiliary Current failure will
appear in the keypads’ Trouble Display (see page50). Therefore, the combined current consumption of devices
connected to the auxiliary power supply should not exceed 700mA. If the auxiliary output is overloaded and is shut
down, you must disconnect all loads from the output for at least 10 seconds before reconnecting any load back to
the auxiliary output.
Modules with the APR- prefix are compatible with Spectra (versions 2.0 and higher) and Digiplex. Modules
with the APR3- prefix are compatible with Spectra( versions 2.0 and higher), Digiplex and DigiplexNE.
