Gamewell-FCI 2451 Photoelectric Detector

DESCRIPTION System Sensor 2451 Series photoelectronic smoke de are specifically designed to meet the performance re of fire detection alarm systems The 2451 and detectors use state of the art optical sensing cham and are designed so that LED failure will not cause an The detectors are designed to provide open area detec and when installed in a two wire base are compatible FCI fire alarm control panels The detectors operation sensitivity can be tested in place The Model 2451T unit the same specifications as the Model 2451 but also fea a built in fixed temperature 135o F thermal detection detectors are of plug in construction and plug into the base as the 1451 series ionization smoke detectors both models interchangeable Bases are available for four wire and 120 VAC four wire operation visible LEDs on each detector flash every ten seconds that power is being applied to the detector The light steadily when the detector is in alarm A remote annunciator is available as an optional accessory 2451 is UL Listed for mounting inside ducts up to a ve of 3,000 FPM testing is performed either by applying a test or inserting a calibrated test card according to the test Field metering of detector sensitivity may be with the aid of a voltmeter and Test Kit 400R SENSOR DETECTOR Easy plug in of the Head to Base Built in Tamper resistant Feature Built in Test Switch Built in Visual Alarm Indicators View Angle Of Alarm LEDs Compatible with FCI Control Panels Field Metering of Detector Sensitivity Removable Insect Screen and Cover Field Cleaning against Dirt Insects and Pressure screening mm openings sensitivity voltage temperature humidity velocity SPECIFICATIONS ft 35 VDC 24 VDC nominal to 120o F 0o to 49o C 93 relative humidity feet per minute maximum flame retardant plastic inches 15.7 cm inches 8.2 cm lb 277 g Southwest Park Westwood MA 02090 USA TEL 781 471 3000 FAX 781 471 3099 ISO 9001 Certified Company 1.1 On a 4 inch square box with or without ring or supplied adapter Minimum 1.5 inches On a 3 1 2 or 4 inch octagonal box Minimum 1.5 inches On a single gang box Min depth 1.5 inches the detector into the detector base Turn the de clockwise until the detector locks into place use the tamper proof feature break the smaller tab the scribed line in the tamper proof tab located on the mounting bracket Install the detector To re the detector from the base when using the tam feature blade of a small into the hole on the side of the base and the plastic lever away from the detector head This allow the detector to be rotated counterclockwise removal NOTE The decorative ring must be re in order to remove the head when using the tam feature tamper proof feature may be defeated perma by breaking the plastic lever off the base The number of two wire smoke detectors can be accommodated per zone varies with dif control panels Consult the control panel in manual to determine the capacity to NFPA 72 Chapter 5 3 Sensing Fire for spacing location of detectors and other may be tested in the following ways Place a test magnet against the cover opposite test module socket See illustration above detector should go into alarm within 5 sec A test card with one end marked the other end marked ALARM is fur with each unit For the complete proce refer to the Installation and Maintenance furnished with each detector SHOWING POSITION OF TEST MAGNET To prevent detector contamination construction smoke detectors must be from dust and contamination until area clean and dust free See NFPA 72 5 3.7.1.3 Field metering of detector sensitivity may be with the aid of a voltmeter and Test MOD 400R the complete procedure refer to the Installation Maintenance instructions furnished with each de programs should be adapted to the individ environment in conformance with NFPA Standard We recommend at the least an annual cleaning of unit The detector screen and cover assembly can be revealing the sensing chamber A vacuum can be used to remove dust from the screen and sensing chamber For the complete proce refer to the Installation and Maintenance instruc furnished with each detector No Model AND TECHNICAL INFORMATION A A Detector Detector w 135oF thermal two wire A C four wire 24 VDC operation A C Supv Base four wire 120 VAC operation A A A B Alarm Indicator of Line Relay 24 VDC Kit Resistive load contact ratings A 2.0 A 30 VAC DC C 2.0 A 30 VAC DC 1.0A 120 VAC Alarm current of detector is limited by control panel initiating device circuit are provided for information only are not intended to be used for installation purposes and are believed to be accurate However no responsibility is assumed by Fire Control Inc for their use Specifications subject to change without notice 2003 All Rights Reserved of 2
