IF 610 Installation and Operation Manual
Issue 3, 10/04/00
Firmware Ver. 7

There are special functions which can be accomplished with the Gamewell Series 610 Fire Alarm Control Panel. One is
Releasing, which allows control of dump or deluge forms of fire suppression.
RELEASING
The Gamewell Series 610 Fire Alarm Control Panel, with version r7 firmware, and Analog Addressable devices, can
provide all of the required functions to control the releasing of bulk fire suppressant materials. The Series 610 FACP is
currently listed for NFPA 11 Low Expansion Foam, NFPA 13 Sprinkler, NFPA 16 Water Foam, NFPA-17 Dry Chemical
types of suppressant and NFPA 2001 Clean Agent suppressant.
NOTE When using the panel for releasing NFPA 2001
agents, a mechanical manual release must be provided in accordance with NFPA 2001
.
Operation
The releasing process is started by the activation of two ANDed initiating devices. When the first of the programmed
pair activates it is displayed on the control panel of the FACP and the Signal Circuit output will provide an audible signal
at the rate 60 bpm. When the second of the programmed pair activates, the Signal Circuit output changes to 120 bpm, and
the Predischarge timer starts. The time period of this timer is programmable from 15 second to 60 seconds. At any time
during this timer period, an Abort switch may be activated to manually intervene in the time cycle. There are five modes
of Abort operation, which are selectable through programming.
1.
One Shot
(Default)
The Abort switch will pause the Predischarge counter as long as the switch is activated.
Upon deactivation of the switch, the counter will resume from where it was paused. Only
one activation of the Abort switch is recognized. Subsequent activations will have no effect
on the Releasing cycle.
2.
Timer
Expiry
The Predischarge timer continues the count down while the Abort switch is activated, the
Releasing process does not occur until the switch has been deactivated, AND the
Predischarge counter has reached zero.
3.
Immediate
The Releasing process commences immediately after the deactivation of the Abort switch,
regardless of the Predischarge timer setting.
4.
10 Second
Delay
NOTICE: This mode does not conform to UL requirements! It is included since it is allowed
by some AHJs
.
The Releasing process commences 10 to 18 seconds after the deactivation of the Abort
switch, regardless of the Predischarge timer setting.
5.
Reset Timer
NOTICE: This mode does not conform to UL requirements! It is included since it is allowed
by some AHJs
.
The Predischarge counter is halted each time the Abort switch is activated, and reset back to
the full programmed delay when the Abort switch is deactivated. This delay cycle can be
initiated as many times as required.
Upon completion of the Predischarge counter cycle, or the programmed Abort operation, the FACP enters into the
Releasing process. The Signal Circuit output will provide a steady signal, and the Discharge delay counter is started. This
counter is programmable from 0 to 30 seconds. At the completion of the programmed delay, the Releasing solenoids are
activated and fire suppressant discharge is performed. A manual
Dump
switch will immediately initiate the Discharge
delay counter, after the deactivation of the Abort switch (if it is activated), regardless of the state of the Predischarge
delay timer.
