TURNING THE 1800 ON

Plug the unit’s transformer into a 120VAC 60Hz outlet. Toggle the power

switch on to start the unit. The System-On LED should glow steadily and

the unit will say “Hello.” The unit will not turn on if AC power is not pres-

ent, regardless of the state of the battery.

Note that when the unit is turned off, all programming is retained in non-

volatile memory.

BACKUP BATTERY

The Sensaphone 1800 includes a 6V 3.4AH sealed lead-acid gel-cell

rechargeable battery for system back-up in the event of a power failure. The

battery will provide approximately 24 hours of backup time. Actual backup

time will depend upon the temperature, battery age, dialing activity, and

state of the relay output. The battery is located behind the main panel.

The 1800 will automatically charge the battery whenever the power switch

is turned on and the power transformer is plugged in. The battery should

provide 3–5 years of service, depending on temperature and charge/dis-

charge cycles, before needing replacement. See Appendix B for battery

replacement instructions.
