<br />EQUIPMENT
<br />
<br />The ESL 609 Series Air Duct Smoke Detector consists of three
<br />primary elements: a) the sensing head, b) the selected function
<br />card, and c) a housing for the detector and function card,
<br />
<br />Duct Detector Housing
<br />
<br />The base section of the housing that mounts to the duct wall
<br />includes: a) integral inlet and exhaust sampling tubes. b) a
<br />sensing head mounting base with an automatic-opening continu-
<br />ity switch, c) a conduit connection plate with ground screw, d) the
<br />detector cover/manifold monitor, and e) the function card com-
<br />partment cover.
<br />
<br />The 609U01 is an air duct detector enclosure supplied with a
<br />611 UD photoelectronic smoke sensing head, The 609U02 is
<br />supplied with a 612UD ionization smoke sensing head,
<br />
<br />Electrical Function Cards
<br />
<br />Any ofthe function cards may be used with the Models 609U01 and
<br />609U02 duct detector assemblies, All function cards include a
<br />local alarm (red) indicator, local test capability, and provision for
<br />remote test and remote alarm indicator connections, All models
<br />except 609U10 include a remote detector reset capability, All
<br />models with auxiliary alarm contacts are Listed as suitable for
<br />releasing service applications,
<br />
<br />Two-Wire Applications
<br />
<br />Three function cards are currently available for two-wire alarm
<br />initiating use, Two-wire detectors must be connected to Listed
<br />compatible initiating circuits, Two-wire function cards do not in-
<br />clude a power-on LED (green), Electrical specifications are shown
<br />in Table 1, below,

<br />
<br />2, When the Model 609U12 function card is used in a two-wire initiating circuit application, the 10 ampere relay must NOT be programmed
<br />for normally operated releasing service, If the relay were to be programmed in this manner, the standby operating current would be
<br />increased from 50 microamperes to 10 milliamperes,
<br />
<br />Low Voltage, Four-Wire Applications
<br />
<br />Seven function cards are currently available for low-voltage. four-
<br />wire alarm initiating and releasing service use, or stand-alone
<br />releasing service applications, All of the low voltage four-wire
<br />function cards can be powered from a nominal 24 VAC source,
<br />available in many HV AC applications, Electrical specifications
<br />are shown in Table 2, on the following page,
<br />
<br />Line or Low Voltage, Four-Wire Applications
<br />
<br />Four function cards are currently available for line voltage (Le"
<br />120 V AC nominal), four-wire alarm operation, All four function
<br />cards can be field modified for low voltage, four-wire opera-
<br />tion by cuttIng Jumper J12 located In the upper right-hand
<br />comer of the function card, below terminals 0 and 1. Four-
<br />wire LinelLow voltage function cards INCLUDE a power-On LED
<br />(green), Electrical specifications are shown in Table 3, on the
<br />following page,
<br />
<br />220/240 V AC Function Card
<br />
<br />The Model609U25 function card is currently the only function card
<br />available for 220/240 VAC, four-wire operation, Electrical speci-
<br />fications are shown in Table 3, on the following page, .
<br />
<br />Field Programming of the 10 Ampere Contacts for Releasing
<br />Service,
<br />
<br />As supplied, the two, 10 Ampere rated, Form C auxiliary contacts
<br />provided with function cards 609U12, 609U 14, 609U22, 609U24,
<br />609U25, 609U32, and 609U34 transfer on alarm ONLY, The relay
<br />that controls these contacts may be field programmed. by moving
<br />jumper J10 from pin P8 to P7, to be energized in the normal
<br />standby condition, so that the contacts transfer on removal of the
<br />sensing head, loss of power to the air duct detector assembly, or
<br />alarm of the sensing head, This may be desirable in many
<br />releasing service applications,
