Edwards Installation Instructions for 5522MD and 5523MD

and 5523MD AW Duotronic for Use in Hazardous Locations Sheet wiring must be of adequate size to prevent excessive drop that would affect signal performance To the minimum wire size required Calculate the value Rmax as follows 7 Number of Signals Determine the total length of the signaling circuit Do not apply power to the unit until is completed and housing cover and outlet cover are secured Select a wire size having a resistance value that is than the value Rmax for the length of signaling wiring required Approximate resistance values 1,000 feet of several commonly used wire sizes as follows AWG ohms 12 2.0 14 3.2 16 5.0 Wires See Figure 2 Remove cover from the outlet box not supplied Note that the outlet box be suitable for use in the hazardous location Feed two power supply wires through the 1 2 NPT conduit supplied into the outlet box Also feed the signal power connection wires either directly into the outlet or if desired through a 1 2 flexible type coupling not and then into box Secure outlet box to signal sealed nipple either directly or by flexible coupling secure conduit to outlet box Connect Wires See Figure 2 Make power supply wiring and make wiring connections to next signal or device in outlet box Observe polarity of signal When making wiring connections to next signal or device ensure that circuit wiring is cut to form incoming and outgoing wires at junctions with leads for proper supervision of connections cover on outlet box Check Signal Operation Apply power to the system panel Initiate an alarm to activate the signal and that it sounds Then reset the panel and verify that signal silences and operation Duotronic signals catalog numbers 5522MD AW and are high decibel diode polarized signaling intended for indoor use in both fire alarm systems systems requiring electrical supervision of signaling circuit wiring The 5522MD AW are horns and the 5523MD AW sirens In fire alarm service applications they meet the dBA minimum at 10 feet 5522MD AW and 5523MD AW are UL listed for use in I Groups B C and D locations for both Divisions 1 and The flange bolts of all series of the signals are sealed in with UL requirements to prevent disassembly and Choose Mounting Locations The horn or siren can be to any solid surface Ensure that mounting provides adequate clearance to enable of the signal to the desired position after The signal position can be adjusted within an 180 degree range vertically or horizontally on mounting of bracket Unit Mount unit in selected location using its bracket and three bolts not supplied See 1 for size and location of mounting holes Signal Direction Adjustment To adjust signal direction the two bolts shown in Figure 1 Rotate the signal the desired position and then tighten the bolts Determine Signaling Circuit Wire Size The signaling 2013 UTC Fire Security All rights reserved 2 3100797 REV 02 REB 21FEB13 and test the unit semi annually for external accumulation of Clean if necessary Test the signal monthly or at the required by applicable regulations and codes 1 Signal dimensions and mounting details 2 Wiring installation and connections specifications power no 2 DC DC A specifications 17.5 Pounds 7.9 kg information contact information see www edwardssignaling com 3100797 REV 02 REB 21FEB13
