No. 2768/2778 series noncoded fire alarm stations <br />are contemporary styled Lexan stations and are flexibly designed <br />to meet a wide variety of application requirements and operational <br />sequences. <br /> <br />The Cat. No. 2768 series are single action stations with terminals <br />for field wiring connections. <br /> <br />The Cat. No. 2778 series are also single action stations but use 6" <br />(150mm) wire leads for field wiring connections. <br /> <br />All types can be either presignal or general alarm and are <br />available with single or double pole alarm contacts which can be <br />normally open, normally closed or a combination of both. Either a <br />key or tool (depending on station selected) is required to reset <br />mechanism. See specification chart for specific catalog numbers <br />and features. Where a manual station is installed on a circuit that <br />also includes smoke detectors, a resistor can be added in series <br />with the alarm initiating contacts on the station so the operation of <br />the station does not extinguish alarm LEOs on operated detectors. <br />The Cat. No. 276-R resistor kits permitfield installation ofthe series <br />resistor on applicable stations. <br /> <br />For semi flush mounting use a standard North-American 4 inch <br />square box with single gang plaster cover having an overall <br />minimum depth of 2-1/4 inches (57mm). For surface mounting use <br />a Cat. No. 276B-RSB surface back box. <br /> <br />WARNING: These devices will not operate without electrical power. <br />As fires frequently cause power interruptions, we suggest you <br />discuss further safeguards with your local fire protection specialist. <br /> <br />!~:_j <br /> <br /> <br />@ <br /><8> <br /> <br />2768/2778 Series <br /> <br />Operation <br /> <br />To initiate an alarm and break the glass rod, pull down on the <br />handle marked "Pull for Fire". <br /> <br />The alarm handle latches in the pulled position until the station is <br />manually reset. To reset, the station is opened using a Cat. No. 276- <br />K 1 key supplied with the station, or a tool; the toggle switch is <br />restored to it's normal position, the break glass rod is replaced <br />and the station is reclosed. For presignal type stations, the general <br />alarm can be initiated by authorized personnel from any operated <br />station by inserting Cat. No. 276-K2 key into the keyswitch behind <br />the alarm handle and turning it clockwise. <br /> <br />Guide Form Specifications <br /> <br />Furnish and install where indicated on plans, Cat. No. (Select one <br />ofthefollowing:) <br /> <br />(2768 series single action manual stations with screw terminals) <br /> <br />(2778 series single action manual stations with 6 inch (150mm) wire <br />leads) <br /> <br />for connection of installation wiring. All stations shall be ofthe <br />noncoded break glass type. <br /> <br />The stations shall be constructed of red lexan with white raised <br />letters. The alarm handle shall be marked "PULL FOR FIRE", to <br />provide simple, concise instructions for activation of station by the <br />general public. <br /> <br />Pulling the alarm handle shall break a glass rod and activate a <br />toggle switch which shall cause the handle to latch in the alarm <br />position. Momentary push button type switches shall not be <br />acceptable. To resetthe station it shall be necessary to open the <br />station using (select one) (a key) (a special tool), restore the toggle <br />switch to its normal position and replace the glass rod. <br />Stations shall be UL listed. <br /> <br />EDWARDS SYSTEMS TECHNOLOGY <br />U.S. SAlES: SARASOTA.
