high intensity strobe utilizes a Xenon flash tube that generates a high-intensity flash visible from all angles. This appliance is intended to provide a visible, audible or audible/visible, depending
on the model, notification signal for the purpose of life safety and property protection. The EC3-24, ES3-24, EC3-12, ES3-12 are provided with a slider switch which allows for candela
selection at the installation site; the candela intensities which can be selected are 15Cd, 30Cd, 60Cd, 75Cd, or 110Cd (24VDC only). The EC24 and ES24 are fixed candela units; the
candela intensities which can be ordered, are 177Cd and 15/75Cd. The W EC24 and W ES24 are fixed candela units, available in a 75 candela intensity only. This appliance is ideal for any
occupancy that requires notification appliances per the applicable building or fire code or wherever dependable alarms are required.
The EC24, ES24, EC3-24, ES3-24, EC3-12, ES3-12 strobe is listed in compliance with ANSI/UL 1971, Signaling Appliances for the earing Impaired (The 15/75Cd model on the

III. MOU TI G, ROUGH-I BOX A D RU WIRI G
This unit is designed for mounting to most single gang boxes, 4" square outlet boxes, 2-gang masonry boxes or non-metallic 2-gang switch boxes. Conduit entrance to boxes should be
selected to insure sufficient wiring clearance.
1. Run a minimum 18 gauge insulated 2 or more conductor cable.
2. Mount a box for each remote signaling appliance. Screw bracket onto box. Insert signal into bracket and slide to the right firmly into the terminal block receptacle. Place housing over
mounted assembly and screw together with single screw at the bottom of the signal. Cover screw with plastic tab.
NOTICE: WIRING S OULD BE CONNECTED TO MOUNTING BRACKET PRIOR TO MOUNTING SIGNAL. INCOMING POSITIVE POWER LEAD MUST BE BROKEN AND EAC LEAD IS
