When solenoid releasing is employed, a means of manually activating the solenoid must also be provided for each release circuit as
required by Underwriters Laboratories. The SG-32SK1 non-coded double action manual release station can provide this capability.
The SG-32SK1 “Fire System Release” manual station is normally installed across the initiating detection zone configured to acti-
vate a solenoid releasing valve. When cross zoning is employed the device is installed on a separate zone solely dedicated to man-
ually activate the appropriate solenoid valve.

The double action station requires that the “PUSH” bar be rotated inward allowing the “PULL” handle to be pulled downward.
This action breaks an acrylic break rod and closes the stations normally open switch contacts, causing the initiating zone to alarm,
activating the solenoid releasing circuit. The station must be reset with a key. Insert the key and turn clockwise to unlock the sta-
tion, open the front cover and return the “PULL” handle to the upright position, then re-lock the station.

Some applications may necessitate the use of deadman abort stations to inhibit the release of extinguishing agents. The
Chemetronics #2-010-0144 deadman abort station is designed to suit such a need. This normally open momentary switch signals
the local control panel to suspend the discharge of extinguishing agents when held in the upward (initiated) position.
%&(*%$
To inhibit the solenoid activation, lift the switch guard cover and toggle the uncovered switch in the up position. This activates the
non-latching switch supervisory circuit
to an alarm state which in turn activates an abort relay in the control panel. This relay inter-
rupts the solenoid release initiating signal. Once the switch is released the abort sequence is disengaged allowing the solenoid to
activate. The supervisory circuit continuously monitors the abort switch status. If the abort switch is activated during a non-alarm
system state, a system supervisory alarm is initiated (see Option “E” or “G”) indicating the off normal placement of the switch. A
wiring fault (open) to the abort switch is annunciated as a switch supervisory trouble condition.
