Information About PR-300
The PR-300 is a Mircom fire alarm interface module designed for City Tie and polarity reversal communication applications. Its City Tie circuit provides a supervised 24 VDC output, while the polarity reversal interface provides separate alarm and supervisory signaling for compatible remote station equipment. The module occupies one system module slot and draws 35 mA during standby and up to 300 mA during alarm operation in documented configurations. Programmable functions allow alarm transmission behavior to coordinate with signal silence and permit an AC power-failure trouble transmission delay of 0, 1, 2, or 3 hours when AC failure is the only system trouble.
Key Features:
- City Tie Interface: Provides a supervised City Tie connection for transmitting fire alarm conditions to compatible receiving equipment.
- Polarity Reversal Interface: Provides polarity reversal alarm and supervisory connections for remote station signaling.
- 24 VDC City Tie Output: Manufacturer product literature specifies a 24 VDC City Tie circuit rated up to 200 mA.
- Low Standby Demand: Draws 35 mA during standby operation in Mircom's PR-300 product specifications.
- Alarm Current: Draws up to 300 mA during alarm operation with the City Tie function active.
- Single-Slot Installation: Occupies one module slot within compatible Mircom fire alarm equipment.
- Programmable Alarm Transmission: Alarm transmit can be configured to turn off during signal silence, permitting manual City Tie box reset where allowed.
- Programmable Trouble Delay: AC power-failure transmission can be delayed by 0, 1, 2, or 3 hours when it is the only active trouble condition.
The PR-300 delivers the reliability and precision required for supervised City Tie and polarity reversal signaling in compatible fire alarm systems.
