<br />Abort Switch
<br />
<br />Features
<br />
<br />. Stackable, screw-terminal, contact blocks
<br />
<br />. Compatible with AUTOPULSE@ control units
<br />
<br />. Surface-mount assemblies listed by Underwriters
<br />Laboratories, Inc.
<br />
<br />. Components mounted on stainless steel switch plate
<br />
<br />Applications
<br />
<br />The Abort Switch is used to momentarily interrupt the release
<br />circuit signal when the control unit is in the alarm condition.
<br />As long as the abort pushbutton is held in, the fire suppres-
<br />sion system will not release. (Note: When the control unit is
<br />programmed for IRI compliance, the abort will not be effec-
<br />tive after pre-discharge.) When the pushbutton is released,
<br />the release circuit is activated (unless the control unit has
<br />been reset to the non-alarm condition).
<br />
<br />Description
<br />
<br />The Abort Switch assembly consists of a momentary-
<br />contact pushbutton switch, normally-open contact block,
<br />normally-closed contact block, and stainless steel switch
<br />plate with silk-screened label. Surface-mount assemblies
<br />include a single-gang weather-proof box with three 1/2 in.
<br />I.P.S. threaded conduit outlets and gasket.
<br />
<br />The stackable, screw-terminal contact blocks are rated for 28
<br />VDC @ 1.1 amp makelbreak or 6 amp continuous carry.
<br />
<br />Listings and Approvals
<br />
<br />The switch is UL listed (S3623) when installed in the surface-
<br />mount box (with gasket) that is provided with the surface-
<br />mount assembly.
