Panel Description and Installation
CAUTION:

NOT apply power until wiring is completed following the procedures described in this manual.
3.1 Panel Description
3.1.1 Phone Line Monitors
The 10-2256 dialer has two phone line monitor circuits, which detect phone line faults by
monitoring their voltages. These circuits feature a 40 to 90 second delay before a line fault is
reported as a trouble. When a fault is detected for longer than this amount of time, the audible
trouble signal will sound, the message will be displayed on the 10-2257 annunciator liquid crystal
display (LCD) (if used), and the trouble will be reported to the central station.
Note: To comply with industry standards, this product is equipped with line seizure. This means that any time the sys-
tem's dialer needs to communicate with the central station, it will NOT be possible to use any telephones that
are on the same line(s) as the fire system. Normally this condition will last less than one minute, but could last
for as long as 15 minutes under adverse telephone circuit conditions.
3.1.2 Watchdog Circuit
If the 10-2256 stops running, the watchdog circuit automatically detects the problem and attempts
to resume normal operation by resetting the communicator. Each time the watchdog circuit resets
the system, it also sounds the trouble signal.
3.1.3 Power Loss Reporting
The 10-2256 will report low AC conditions. For Cheetah the 10-2256 monitors the trouble relay.
For SHP/Rhino the 10-2256 monitors the control panel's main AC power input.
The AC report delay time is programmable. See Section 5, Step 20.
