FEATURES

Keypad Programming
The PC2550 comes with a default program so it is operational
with a minimum of programming. It is completely
programmable from the keypad. The panel uses EEPROM
memory so that all information is retained even if the panel
loses both AC and battery power.
Multiple Level Static/Lightning
Protection
The PC2550 has been carefully designed and tested to
provide reliable service. It is built to take static and lightning
induced surges and keep on working. Multiple level surge
filters are on all zone inputs, the power supply, the keypad
connections, the bell output, the auxiliary power supply and
the telephone interface. A special "ZAP-TRAC" circuit
board configuration catches high voltage impulses right at
the wiring terminals. Protective ground planes surround
sensitive areas preventing the spread of damaging voltage
surges. Metal Oxide Varistors (MOV's) are placed in all the
critical areas to further reduce impulses to safe levels.
"WATCHDOG MONITOR" Circuit
Even when all precautions are taken so that voltage surges
do not cause damage to the control panel, it is possible to
cause temporary disruption to the operation of the
microprocessor causing it to lose track of the program
sequence. The PC2550 is equipped with an external
"Watchdog Monitor" circuit which continually checks the
microprocessor program execution.
System Supervision Features
The PC2550 continuously monitors a number of possible
trouble conditions including:
• An active battery supervision circuit that periodically tests
the battery under load.
• A loss of the AC power supply.
• A supervised fire circuit trouble condition.
• A telephone line monitoring circuit.
• A bell circuit failure indicates open circuit or fuse failure.
• A test code feature which transmits a communicator test
code to the monitoring station at a selected time
everyday. The test code can be sent at intervals from 1 to
99 days.
• A bell/siren/communicator test feature which can be
activated from the keypad.
• TLM (Telephone Line Monitoring) restoral transmission.
Advanced Features
The PC2550 has many advanced features. Features which
provide the security system design flexibility and selling
advantage necessary to win those demanding jobs and
make them profitable.
Some of these features include
• EEPROM memory retains all data even on complete AC
and battery failure. Panel powers up in last armed or
disarmed state before power loss.
• All programmable zones may be selected as one of 10
different types including; delay, auxiliary delay, instant,
interior, interior with home-away, delay with home-away,
and 4 types of 24 hour emergency and supervisory
circuits.
• Keypad programming of up to sixteen security codes.
• Zone bypassing from the keypad.
• Individual zone and system function indicators on keypad.
• A keypad activated utility output function for operating
lights, door openers, cameras or other devices.
Although the PC2550 has many features, it is not difficult to
use. All keypad commands are similar and are assisted by
audible and visual cues.
