Autocall A4098-9846 Sensor Guard for TrueAlarm Sensors

UL, ULC listed, FM Approved* Autocall TrueAlarm sensors and bases (ordered A4098-9714, Photoelectric sensor A4098-9754, Multi-Sensor, Photoelectric and Heat A4098-9733, Heat Sensor A4098-9792, Standard Sensor Base A4098-9791, Relay Control Base A4098-9789, LED Output Base A4098-9793, IDNet Isolator Base features: For ceiling or wall mounted sensor applications Combines accurate, individually addressable analog smoke and/or heat with physical protection TrueAlarm analog sensing provides compensation for air flow by providing maintained high sensitivity Photoelectric smoke sensitivity is selectable from 0.5% ft. to 1.5% ft. at fire alarm control unit The host control unit automatically compensates for sensitivity shifts by contamination and automatically reports dirty devices UL listed to Standard 268 (URRQ) and 521 (UQKE) ULC listed to Standard 529 (URRQC) and 530 (UQKEC) options: Standard mounting of A4098-9846 is for use with flush mounted boxes electrical box Extension box A4098-9847 is required for mounting to surface resistant design: Heavy duty steel construction, single wall Tamper resistant grill mounting screws Guard A4098-9846 the sensitivity and maintained accuracy of Autocall TrueAlarm with a rugged, tamper resistant enclosure. Typical applications correctional and detention facilities, mental hospitals, industrial educational facilities, dormitories, and many other locations the smoke sensor may be intentionally or accidentally subjected abuse. Reference this combination, the sensor can be located directly in the ceiling a detention cell or similar area and can provide accurate and quick of smoke and/or heat conditions. Additionally, after removing tamper resistant hardware, the sensor is readily accessible for when the TrueAlarm system automatically identifies the need maintenance.

NFPA 72, the National Fire Alarm and Signaling Code, Section 5.4.3 (2007 Edition): “Where subject to mechanical damage, an initiating device be protected. A mechanical guard used to protect a smoke, heat, or radiant energy detector shall be listed for use with the detector.” guard A4098-9846 is for use only with a Autocall A4098-9714 Photoelectric Sensor or a A4098-9754 Photo/Heat Sensor with a restricted range of 0.5 to 1.5% per foot obscuration; or with a A4098-9733 Heat Sensor; and for use only with sensor bases A4098-9789, A4098-9791, or A4098-9793. This will ensure the sensor will activate within the UL listed obscuration range when mounted in the sensor guard. Note: For proper performance, follow installation instructions and review sensor and guard locations carefully. Wall mounting may not be for institutional or detention applications. Issue. The presence of debris on the sensor guard grill will significantly restrict airflow into the sensor. It is recommended that visual maintenance be performed to ensure
