XQC-CS602Audio Detector

70 CS-602 AUDIO DETECTOR patent pending Installation Manual & Users Guide SPECIFICATIONS Frequency: 345MHz Battery: One 3Vdc lithium CR123A Battery life: up to 4 years Detection distance: 6 in max Operating Temperature: 32°-120°F (0°-49°C) Operating Humidity: 5-95% RH noncondensing Compatible with 345MHz ClearSky Hub Supervisory signal interval: 70 min(approx.) Maximum current draw: 23mA during transmission OPERATION The FireFighter™ sensor is designed to listen to any smoke, carbon or combo detector. Once confirmed as an alarm, it will transmit a signal to the alarm control panel which if connected to a central monitoring station, will dispatch the fire department. WARNING:This audio detector is intended only for use with smoke, carbon and combo detectors but it does not detect the presence of smoke, heat, or fire directly. ENROLLING To enroll the sensor remove the top cover by depressing the friction tab in order to reveal the battery. Pull and discard the battery plastic tab to turn on the device. Download and install ClearSky App on your android or IOS phone. Open yourClearSky APP and follow the directions on the app to learn in the sensor. App will require you to press the learn button when linking (Image 1). There are 2 modes of detection on the FireFighter™. Mode 1 is smoke only and Mode 2 is smoke and carbon monoxide alert detection. To switch between modes, remove the battery, press and hold the tamper switch and learn button until a red LED turns on. Let go of tamper and learn button. 1 red blink indicates smoke alert detection. 2 red blinks indicates smoke + CO alert detection. MOUNTING Included with this device is a mounting bracket, hardware and double sided tape. To ensure proper operation ensure the side of the device with the small holes is directly facing the sounder holes on the smoke detector. Secure the mounting bracket to the wall or ceiling using the two mounting screws and double sided tape provided, then secure the audio detector to the mounting bracket using the small screw provided.The FireFighter™ must be mounting within 6 inches of the detector for optimal operation. WARNING:No n-interconnected smoke detectors require an audio detector by each smoke detector sounder. This equipment should be installed in accordance with Chapter 2 of the National Fire Alarm Code, ANSI/NFPA 72, (National Fire Protection Association, Batterymarch Park, Quincy, MA 02269). Printed information describing proper installation, operation, testing, maintenance, evacuation planning, and repair service is to be provided with this equipment. Warning: Owner’s instruction notice: ’Not to be removed by anyone except occupant’. A Universal Electronics Company TESTING To test the RF transmission from the mounted position you can either generate a tamper by removing the cover or press the learn button located next to the tamper switch. Press and release ONCE to send a Smoke signal or press and HOLD for 2 seconds to send a Carbon signal. To test the audio detection, press and hold the smoke detector test button. Press and hold the smoke detector button for at least 30 seconds to ensure that FireFighter™ has had sufficient time to identify the smoke alarm pattern and lock into alarm. Ensure the FireFighter™ cover is on and that you wear hearing protection. NOTE: This system must be checked by a qualified technician at least once every three (3) years. Please test the unit once per week to ensure proper functionality. LED The Firefighter™ is equipped with a multi-color LED. When a valid audio signal is heard the LED will turn red and flash in sequence to the smoke detector sounder. When the Firefighter™ has determined the audio signal heard is a valid alarm, the LED will turn solid green to indicate it has transmitted to the panel. The LED will blink yellow following the detected alarm tone. On power up, the LED will blink red to show which mode it is in, once for smoke only, twice for smoke + CO detection mode. REPLACING THE BATTERY When the battery is low a signal will be sent to the control panel. To replace the battery: 1) Remove the FireFighter™ from installation location by sliding the unit off the wall/ceiling mount in the direction indicated on the FireFighter™ Cover. 2) Unscrew the two screws on the back of the FireFighter™. Remove the top cover by depressing the friction tab in order to reveal the battery. This will send a tamper signal to the control panel.) 3) Replace with a Panasonic CR123A battery ensuring the + side of the battery faces as indicated on the device. 4) Re-attach the cover, you should hear a click when the cover engages properly. Then replace the screws removed in step 2. 5) Replace the on the mounting plate from step 1. WARNING:While the audio detector monitors its own battery, it does not monitor the battery in the smoke detectors. Batteries should be changed as per the original smoke detector manufacturer’s instructions. Always test the audio detector and smoke alarms after battery installation to confirm proper operation IMAGE 1: ENROLLING / TEST / TAMPER BUTTON TAMPER SWITCH LEARN BUTTON IMAGE 2: INSTALLATION DISTANCE HOLES TO LINE UP WITH EXISTING SMOKE DETECTOR IMAGE 3:SIDEMARKINGS PACKAGE CONTENTS Included Items: 1 x FireFighter™ Wireless Audio Detector 1 x Mounting Plate 2 x Mounting Screws 2 x Double Sided Tape 1 x CR123A battery 1 x Installation Manual FCC Compliance Statement This equipment has been tested and found to comply with the limits for Class B digital devices, pursuant to Part 15 of the FCC Rules.
