The following hardware configuration must be performed before installing the PR-300.
Table 2: PR-300 Cable and Jumper Settings
The Alarm Transmit signal to the PR-300 can be programmed to turn OFF when signal silence is active. This allows
the City Tie Box to be manually reset. On subsequent alarms the silenceable signals will resound and the City Tie
Box will be retriggered.
The Trouble Transmit signal to the PR-300 can be programmed to delay AC power fail 0, 1, 2, or 3 hours if this is the
only system trouble.
RAX-332 Display Adder Module
The RAX-332 Display Adder Module is used only with the FX-351 and FX-353 Fire Alarm Panels. No jumpers or
other physical configuration steps are required to install this second RAX-332 Display Adder Module. Remove the
blank cover plate from the front door and install the RAX-332 with the clear cover in the opening with the hardware
provided. Disconnect main and standby power and connect the cable of the second RAX-332 into the open,
remaining header of the existing RAX-332. The additional LEDs will be available for configuration as LEDs 33 to 64,
when the system power is restored.
