waterflow alarm devices Trouble Relay Stock No 5190147 Model ULT Stock No 1000391 if by authority having Model EFT C is an electric motor driven for use on McCulloh type signal adjustment on the circuit board provides motor speed adjustment from 1 to 4 pulses per second transmitter provides a Class A supervised circuit for connection of NORMALLY devices such as heat sensor thermo smoke and ionization detectors alarm switches and manual pull sta The EFT C utilizes an external low voltage transformer A built in battery charger the battery which provides in excess 72 hours of standby operation A low battery circuit insures battery integrity SPDT alarm contacts are provided and an plug in relay is available to provide trouble contacts An electronic retard approximately 60 seconds delay on alarm transmission if desired see 1 Fig 2 One round trouble signal indicates low battery or open detection circuit condition indicated by yellow LED on board reset switch to restore from trouble to normal when cause of trouble con has been corrected Four round alarm signal when Class A circuit is shorted by detection device round alarm signal from trouble condi Alarm condition indicated by red LED One round restore signal from to normal is automatic when short is from Class A detection circuit Electric Signal Company cid 127 2081 Craig Road St Louis MO 63146 4161 cid 127

FIRE ALARM EFT C contains Limited fire protec signaling circuit conductors and Class 1 elec Limited circuit conductors control unit enclosure provides multiple cable openings so that the Limited fire signaling conductors can be segre from the Class 1 electric Lim conductors cable entry opening in the top should used for the Class 1 Limited as the power inputs are located in this two bottom enclosure cable entries must be for the Limited fire protective signal conductors specific wiring routing see Fig 4 4 ROUTING must be installed from back side of terminal block Battery wire terminals 21 and 22 have spaghetti from terminal to hole in P C board Cover tamper wires are covered with spaghetti and run from terminals 1 and 2 under P C board the lower right hand standoff to the tamper switch this is factory installed wiring Wires from terminals 3 through 12 exit through lower left hand side knockout Wires from terminals 15 through 20 exit through the top center knockout IN USA
