INSTALLATION AND MAINTENANCE INSTRUCTIONS 3825 Ohio Avenue, St. Charles, Illinois 60174 FAX: 630-377-6495 and 1424 Direct Wire Smoke Detectors 5.5 inches (14 cm) 3.12 inches (8.0 cm) 0.7 lb (310 gm) Temperature: 0 to +49 (32 to 120 Humidity: 10% to 93% Relative Humidity Non-condensing Alarm: Reset by momentary power interruption. Contact Ratings or Inductive (60% power factor) load A: 2.0A @ 30VAC/DC C:* 0.6A @ 110VDC, 2.0A @ 30VDC 1.0A @ 125VAC, 2.0A @ 30VAC Canadian installations, relay contact rating is 2.0A @ 30VAC/DC Ratings: 1412 1424 Voltage: 12 24 DC (4V Maximum Ripple) Voltages: 11.3 20 VDC Minimum 17.3 29 VDC Maximum Voltages: .73 .8 VDC Minimum Current: 100 100 Maximum Currents: 35.2 21.3 mA Minimum 77.0 40.6 mA Maximum alarm and auxiliary relay operate within the specified voltage ratings. Time: 0.3 0.3 Seconds Time: 30 30 Seconds Installing thoroughly read the System Sensor manual A05- Applications Guide for System Smoke Detectors, provides detailed information on detector spacing, zoning, wiring, and special applications. Copies this manual are available at no charge from System (For installation in Canada, refer to CAN/ULC- Standard for the Installation of Fire Alarm Systems CEC Part 1, Sec. 32.) Description Sensor 1412 and 1424 dual-chamber ionization detectors utilize state-of-the-art, unipolar sensing These detectors are designed to provide open protection, and to be used with UL-listed 4-wire con- panels. The 1412 for 12 volt panels operates at 12VDC, the 1424 for 24 volt panels operates at 24VDC. The operation and sensitivity can be tested in place. detectors are listed to UL 268 and are latching type detectors. When latched in alarm, the detectors be reset by a momentary power interruption. LED on the detector provides a local indication of the status. If power is applied to the detector, and detector is functioning properly in standby, the status will blink every 10 seconds. In alarm, the LED will be on continuously until the detector is reset. detector contains one Form A (SPST-NO) contact for to the alarm-initiating circuit, and one Form (SPDT-NO/NC) set of auxiliary contacts. Supervision detector power is accomplished by installing a Power End-of-Line Relay Module (A77-716) at the end the detector power loop. When power is applied to and the detectors, the EOL Power Supervisory Module energized. Its relay contacts close and provide a closed circuit in the control panel alarm-initiating loop. A failure or a break in the detector power loop de-ener- the EOL Module. The relay contacts open and trigger trouble signal at the control panel. 1 I56-280-05R 1.
