ESL 700 Series Conventional Smoke and Heat Installation Sheet base for all heads 4 in 10 cm base for all heads 6 in 15 cm base for 731U 4 in 10 cm base for 731U 6 in 15 cm with base sold together photoelectric smoke detector with alarm relay output and remote alarm trouble LED output UL Listed for releasing devices such as electromagnetic door fire dampers or smoke dampers voltage 120 V base and head 702RE and 702RU bases have a special plastic protrusion in to prevent insertion of a low voltage detector head into base containing damaging high voltages 120 V These can only be used with 731U heads The 731U includes relay contacts and is only required when connecting voltage to the auxiliary relay The 731U heads can also be used with 702E and 702U for low voltage applications ESL 700 Series smoke or smoke with rate of rise heat have field replaceable optical chambers The uses an optical sensing chamber to detect smoke and fixed temperature heat sensor to detect heat from fire For

base detectors in an operating environment as defined on page 6 Mount detectors on a firm permanent surface and spacing the following location guidelines to optimize performance reduce the chance of false alarms detectors wall mounted smoke detectors so the top of the is no lower than 12 in 30 cm below the ceiling Figure 1 a guide space smoke detectors on smooth ceilings ft 9.1 m apart When determining other spacing ceiling height high air movement and other or response requirements Refer to NPFA 72 detectors away from air conditioners heating and any other ventilation source that may with smoke entering the unit also away from wood stoves garages furnaces and bathrooms detectors Do not install heat detectors in areas with an ambient above 100 38 Mount heat detectors on the ceiling no closer than 4 in the sidewall On the wall mount them between 4 and in from the ceiling When determining detector placement consider ceiling construction and ventilation as these affect a performance Refer to NPFA 72 the base a compatible electrical box for the base See on page 6 for a list of compatible electrical 6 inch diameter bases have three parts the base itself mounts on the electrical box or ceiling a foam gasket and base cover that conceals the mounting screws see 1 for model numbers and descriptions The 6 inch bases are shipped loosely coupled to the base cover Base cover Screwdriver slot to unlock Gasket Base head 6 13083 EN REV J ISS 10APR14 the detector head remove the detector head turn it counterclockwise If the tab was removed insert a small screwdriver into the tab slot on the side of the base and then press in while turning the detector head counterclockwise Figure 5 5 Removing the detector head with the locking tab Risk of system failure The system may not operate if detector is not connected to the control unit initiating device as specified in the detector or control unit literature two wire installation see Figure 6 four wire installation see Figure 7 optional four wire operation verify that the voltage range of control panel power supply is within the detector voltage and that sufficient current is available to ensure the of all detectors supervision for four wire systems 72 requires supervision of power wiring in four wire To accomplish this install a power supervision unit the appropriate control unit voltage at the end of the power circuit See Figure 7 model 204 12 24V power supervision relay both 12 VDC and 24 VDC operation See the V installation sheet for more information install the base Remove the base cover by simply twisting it counter to unsnap see Figure 2 Pull the field wires through the electrical box and then the center opening of the base Connect the wires the appropriate terminals according to the wiring see Figure 6 or Figure 7 Dress the wiring neatly and then verify that the continuity jumper wire is touching both terminal 1 and 2 see Figure 8 Securely fasten the base with appropriate hardware Check all wiring and mounting connections the gasket Align the molded line on the base with base cover and then twist clockwise to snap in place the locking mechanism before installation detector head is equipped with a breakaway locking tab prevent unauthorized removal of the detector head see 3 For installations where unauthorized removal of the head is not a concern the head removes by simply counterclockwise when the head must lock to the base break away locking tab with a pair of pliers Then to remove the head insert a small screwdriver into the slot on the of the base pressing in while simultaneously turning the head counterclockwise see Figure 5 3 Removing the locking tab slot To lock break out this tab with pliers the detector head install a detector head insert the head and rotate it to properly align and seat it into the base see 4 Then rotate it an additional 15 degrees to lock it in This action automatically opens the continuity switch in base and establishes continuity in the system 4 Installing the detector head Head Base 13083 EN REV J ISS 10APR14 6 6 700 series two wire wiring diagram 7 700 series four wire wiring diagram 741UT head 702E
