AC POWER
Do not use switch-controlled outlets to power the transformer. Connect the 16.5VAC 40VA transformer as shown in Figure 8-1: PCB Layout on
page 13.
2.4
BACKUP BATTERY
Complete all the wiring before connecting AC power and the battery. After establishing AC power, connect the 12VDC 4Ah rechargeable acid/
lead or gel cell backup battery by connecting the red battery lead to the positive battery terminal (

AUXILIARY POWER TERMINALS
The auxiliary power supply terminals provide 400mA and can be used to power motion detectors and keypads in the security system. A 1A fuse
protects the power supply against current overload, which must be replaced if the current exceeds 1A. Therefore, the combined current
consumption of devices connected to the auxiliary power supply should not exceed 1A.

BELL OUTPUT CONNECTIONS
Bells, sirens and other warning devices requiring a steady voltage output during alarms are powered by the bell relay and the bell output, which
is protected by a 3A fuse. Connect the siren's positive lead to the panel's
and connect a wire from the relay's COM terminal to the

PROGRAMMABLE OUTPUT (PGM) CONNECTIONS AND PROGRAMMING
Section [13]
The Spectra 1727 control panel includes two programmable outputs (PGMs) that provide a maximum of 50mA each. When a specific event
occurs in the system, a PGM can reset smoke detectors, activate strobe lights, open/close garage doors and much more. Connect the PGMs
according to Figure 8-3: PGM Connections on page 14.
In section [13] you program the event that will trigger the PGMs. The PGM will remain activated as long as the event is occurring. The first digit in
the section controls PGM 1 and the second digit controls PGM 2. The available events are listed in Table 2 on page 4. For example, if you want
to program PGM 1 to activate during the Exit Delay and PGM2 to activate during an alarm, in section [13] program [0] then [5]. The default is set
at 3/3 (PGM1 and PGM2 activate when the
