Autocall In-Duct Mounting of the A4098-9714 TrueAlarm Photoelectric Smoke Sensor

Datasheet Analog Sensing Mounting of the A4098 9714 TrueAlarm Photoelectric Smoke Sensor ULC CSFM Listed FM the model A4098 9714 TrueAlarm analog photoelectric directly inside air ducts Accommodates duct airflow from 0 to 4000 ft min 0 to 1220 m min HVAC duct smoke sensing where sampling tube designs are appropriate refer to Specifications for more information For applications with controlled dust and humidity Standard models are for rectangular ducts from 6 152 mm square to 914 mm square Optional adapters allow use with round ducts of 6 8 203 mm 254 mm or 12 305 mm in diameter TrueAlarm analog communications can be either IDNet format Model A4098 9714 sensor is required and ordered separately alarm led indicator in housing Visible through transparent housing cover Pulsing indicates power on steady on indicates alarm or trouble as at the fire alarm control panel A4098 9750 provides two wire operation no relay output A4098 9751 provides a local relay Relay operation is programmable from fire alarm control panel and is 1 A 28 VDC power limited or 1 2 A 120 VAC non power 24 VDC power is supplied by fire alarm system 4 wire operation Adapters for 6 8 10 or 12 round ducts Remote Test Station A2098 9806 Remote LED Alarm Indicator A2098 9808 listed to Standard 268A Please note that smoke detection in air ducts is intended to notify the presence of smoke in the duct It is not intended to and will not smoke detection requirements for open areas or other non duct 1 Housing with A4098 9714 mounted in 8 square duct for reference air ducts air ducts in buildings supply fresh air and exhaust stale air on the overall fire detection requirements smoke detection be required in the air ducts For applications where sampling tube duct detection is not appropriate due to low air velocity or small size Autocall model A4098 9750 and A4098 9751 housings can be to install the Autocall model A4098 9714 TrueAlarm analog sensor in the duct Refer to data sheet AC4098 0030 for smoke sensor with sampling tubes housings mount a spot type smoke sensor directly into the duct Proper application requires controlled dust and humidity note that in the event of loss of duct airflow the A4098 9714 sensor will smoke IF the smoke reaches the sensor However with no duct smoke may not reach the sensor depending on the location of smoke source relative to the sensor Operation a A4098 9714 sensor in an air duct provides the high reliability of TrueAlarm analog sensing featuring programmable consistent accuracy environmental compensation status and monitoring of sensor dirt accumulation These housings communicate their analog sensor information to the fire alarm panel using IDNet two wire communications Model A4098 9751 provides a relay that can be programmed to track local sensor operation or can be independently controlled by the alarm control panel to perform fire response actions such as fan and damper control This product has been approved by the California

location must ensure adequate airflow within the duct housing Ensure accessibility for test and service Proper Locations downstream side of filters to detect fires in the filters in return ducts ahead of mixing areas upstream of air humidifier and coil Other locations may be required for proper duct smoke detection depending on duct access system design and duct airflow testing Contact local Autocall product supplier for assistance to Avoid Where dampers closed for comfort control would interfere with airflow Next to outside air inlets unless the intent is to monitor smoke entry from that area return air damper branch ducts and mixing areas where airflow may be restricted Information Refer to NFPA 90A Standard for the Installation of Air Conditioning and Ventilating Systems NFPA 72 the
