PFC-4410RC • 5403550 • REV Q • 11/12

Control Buttons

• Signal Silence - Momentary, silences signaling circuits, (except those activated by zones programmed as WATERFLOW)

• System Reset - Momentary, resets all alarm circuits if condition has been corrected, removes power from initiating device

circuits.

• Scroll Up - Scrolls LCD display to most recent events

• Scroll Down - Scrolls LCD display to previous events

NOTE: Buzzer silence is accomplished by scrolling through all events.

Notication/Release Circuits

The indicating circuits of the PFC-4410RC are Non-coded. This allows the use of visual and audible appliances on the same

circuit. If temporal notication appliances are required for evacuation, selectable tone appliances such as the AMSECO H24WR

horn or SH24W Series strobe/horns or a temporal module such as AMSECO TMP1-3A or equivalents shall be used.

The notication outputs do not provide synchronization. See table for sync options and devices on page 89. The notication ap-

pliances shall be compatible with the sync module selected. The sync' module shall be installed as per manufacturers instructions.

Synchronization is limited to only one circuit and not between circuits. Systems intended for the release of Halon 1301 as de-

scribed in NFPA 12A, or clean agents as described in NFPA 2001, shall have provision for a pre-discharge notication circuit. If

the signal is required to be separate and/or distinct from the evacuation signal, two notication circuits are required. One shall be

programmed as FIRST ALARM. It will provide a steady output upon activation of any initiating zone programmed as an alarm

zone. This is the evacuation signal. If a temporal signal is required, notication appliances such as AMSECO model H24WR or

others that can produce a temporal tone shall be used. This allows the use of strobes and horns on the same circuit. The other no-

tication circuit shall be programmed as SECOND ALARM. It will provide a steady output upon activation of a second initiating

zone programmed as an alarm zone. This is when the pre-discharge timer would start and would be the pre-discharge signal. If a

temporal or other type of signal is required, notication appliances such as AMSECO model H24WR or equivalent shall be used.

This allows the use of strobes and horns on the same circuit. If a separate signal for discharge were required, a third notication
