| 1012B/2012B Direct-Wire Smoke Detector with Built-in Relay and Horn A Division of Pittway 3825 Ohio Avenue, St. Charles, IL 60174 1-800-SENSOR2 (736-7672), Fax 630-377-6495 http://www.systemsensor.com Models Available 1012B Ionization Detector 2012B Photoelectronic Detector Features * 12 VDC operation, 4-wire * Built-in 85dB electronic horn * Built-in relay can be connected to lights, bells, horns, remote annunciator, or control panel * Interconnectable up to 12 units * Visual alarm and power indicator * Ceiling white color * Built-in 8 second delay on relay output * Built-in test switch * Twist-on mounting bracket with tamper option for easy installation * Improved chamber design for greater stability * Same housing design for both ion and photo models * 3-year warranty Compact, attractive, and easy to install, System Sensor 1012B and 2012B detectors are designed to respond to a broad range of fires while providing maximum stability. Both units in this series feature low-voltage wiring, allowing you to choose the detector that best suits your application. Specifications Size: Weight: Humidity Range: 1.75 h x 5.5 dia. (44.5 mm h x 140 mm dia.) 5.3 oz. (150 grams) 10% to 93% RH, noncondensing Smoke Detector Spacing: On smooth ceilings (as defined in NFPA 72), spacing of 30 feet (900 sq. ft.) may be used as a guideline. Other spacing may be used depending on ceiling height, high air movements, and other conditions or response requirements. Electrical Ratings Operating Voltage: Relay Contact Rating: Standby Current: Alarm Current: Temperature Range: 12 VDC (nominal) 1 Form A, .5 A @ 30 VDC 50 A maximum average 20 mA maximum average @ 12 VDC 32 to 120F (0 to 50 C) (c) System Sensor 8/96 This document is not intended to be used for installation purposes. A05-238-02 General Description System Sensor 1012B ionization and 2012B photoelectronic detectors are designed primarily for applications where low-voltage Class 2 wiring may be used. These detectors are self-resetting and offer an 85dB alarm horn. An external push button provides a test of the detectors' alarm function. Up to 12 units can be interconnected so that if one detector alarms, all detectors alarm. A normally open auxiliary alarm relay is available for controlling external functions. A visible LED indicator flashes once every 40 seconds in standby and rapidly in alarm when detecting smoke. The detectors offer low-voltage operation and a tamper-proof feature. Screw terminals and a mounting bracket are provided for easy installation.
