If used, the Remote Annunciator operates within the specified detector alarm currents. Voltage: 2.5 VDC Minimum Time: 0.3 S Maximum Time: 34 S Maximum Installing thoroughly read the System Sensor manual A05- Applications Guide for System Smoke Detectors. This provides detailed information on detector spacing, zoning, wiring, and special applications. Copies this manual are available at no charge from System (For installations in Canada refer to CAN4-S524, for the Installation of Fire Alarm Systems and Part 1, Sec. 32). This manual should be left with the owner/user this equipment. This sensor must be tested and maintained following NFPA 72 requirements. This sensor be cleaned at least once a year. 2400, but also features a restorable, built-in, fixed (135 thermal detection unit. 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. This LED blinks every 10 seconds when detector is receiving power and ready in standby and latched on continuously in alarm until the detector is The detector provides an output for connection to optional Remote Annunciator (Model RA400Z). The Annunciator mounts to a single gang box and pro- a supplementary alarm indication. Description Sensor 2400 photoelectronic detectors use state- optical sensing chambers. These detectors are to provide open area protection, and are intended use with compatible UL-listed 2-wire control panels The detector operation and sensitivity can be tested place. Model 2400TH has the same specifications as 1 I56-285-05R 72E defines the spacing requirements for smoke typically 30 feet when detectors are installed on smooth ceiling. However, ALL installations must comply NFPA 72 and/or special requirements of the authority jurisdiction. 1.
