HONEYWELL Security & Custom Electronics 149 Eileen Way Syosset NY, 11791
Architect and Engineer Specification for: IS2535 PIR
DESCRIPTION: Document – Architects/Engineer Specification Model – IS2535 Product Description – PIR Intrusion Detector Note – Words/statements within square brackets  may be included when appropriate, or when selection is required. OVERVIEW: The Intrusion Detector[s] shall operate on the Verified Intrusion principle using Passive Infrared (PIR), and shall be listed by Underwriter’s Laboratories, Inc (cULus), SIA PIR-01 False Alarm Immunity standard, CE. INTERFACE AND ENCLOSURE: Each detector shall provide the detection, signal processing, alarm relay, and operating power circuitry in the same enclosure; and shall provide an alarm relay actuation upon the detection of an intruder moving into or through its protection pattern. The enclosure should be ready for surface and/or corner mounting, and shall be capable of mounting to a compatible Wall or Ceiling mounting bracket without modification. Each detector shall feature a single piece electronics board. The board shall have a snap fit into the rear housing. The rear housing shall be secured to the front housing with a snap fit and an optional screw. The enclosure should have a large rear wiring channel, shall include easy wiring knockouts, and shall provide wire strain relief points. LED OPERATION:
Each detector shall incorporate a single, Red LED to indicate the operating conditions. Red LED illuminated for 3 seconds shall indicate an alarm condition. Red LED not illuminated shall indicate a non-alarm condition. The Red LED blinking fast shall indicate a trouble condition. During initial power up, the Red LED shall blink slowly for up to 3 minutes while the circuits stabilize. The LED indicator shall be optional; it shall be capable of being field disabled using the On/off dip switch. Even if disabled, the LED shall stay enabled for 10 minutes after power up and/or for 10 minutes after the LED dip switch is toggled On to Off, to allow the installer or site manager to walk test the pattern. POWER REQUIREMENTS AND CURRENT CONSUMPTIONS: The detector[s] shall be capable of operating from a DC power source rated within the range of 8.5 to 15.4 VDC. The detector[s] current draw shall be 17 mA nominal, and 20 mA maximum at 12 VDC. The detector[s] shall withstand AC ripple from 50 to 120 Hz, 3 V peak-topeak at nominal 12 VDC. ALARM OPERATION: A condition of alarm shall occur when the PIR alarm conditions are met. The Detectable speed shall be 1~10 ft/sec. (0.2~3m/sec.). The alarm period shall be approximately 3.0 +/- 0.5 seconds. The alarm output shall be capable of handling 24 VDC, 30 mA max. The detector shall have 4 sensitivity settings selectable via dip switch. The sensitivity settings shall include Lowest, Low, Medium and High for times when the detector is installed in a hostile area, and times when greater sensitivity is required. Each detector shall signal the condition of alarm using a Normally Closed Relay with 45o terminal strip connections. The 45o terminal strip allows easier installation and the ability to inspect the wiring connection for a more reliable operation. To accomplish PIR detection, each detector shall contain a sealed Pyro-Electric sensor peaked for the detection of near-infrared energy in the 10 micron region. The sealed area shall be black in color, providing enhanced immunity to false triggers caused by bright lights, and shall provide White light immunity to 6500 Lux minimum.
The detector[s] shall use a solid state relay to transmit the alarm condition. The solid state relay is quiet in operation, for use in any environment where discretion or high security is a premium. The solid state relay can not be compromised with a magnet, for use in high security installations.
SENSOR STABILITY AND PERFORMANCE: The PIR detection shall use a balanced Dual Opposed Element detector to guard against unwanted alarms caused by changes in infrared energy not associated with motion. To guard against false activations caused by RF interference, the detector shall incorporate RFI protection. No alarm shall occur at 30 V/m within the range of 10-1000 MHz. A dual slope temperature compensation circuit shall also increase detection capability under high temperature conditions where the background temperature is similar to that of the human body. ENVIRONMENTAL CONDITIONS: The detector[s] shall be rated to operate within the temperature range of [14o Fahrenheit to 131 o Fahrenheit][minus10o Celsius to 55 o Celsius]. The detector[s] shall tolerate an environmental humidity rate of 5% to 95% maximum, non condensing. No false alarm shall occur within these operating conditions. OPTICS: The detector[s] shall use Fresnel lenses, and the optics chamber shall be sealed to eliminate the chance of a false alarm due to drafts or small insects. SELF TEST: The detector shall incorporate self tests of the PIR channel as well as the temperature compensation components to ensure proper circuit operation. The self test routine should run on power up and routinely during operation. If the PIR self test fails, the alarm relay shall latch open (in alarm) and the LED shall blink fast. If a valid PIR signal is subsequently seen, the trouble will automatically clear itself and the detector will return to normal operation. If the temperature
compensation self test fails, the detector will default to its room temperature settings and flash the Red LED fast, and on the next alarm condition, the detector will latch the alarm relay open (in alarm). LENS AND DETECTION PATTERNS: Each detector shall contain a front mounted hard and durable Fresnel lens that shall focus the received infrared energy onto the sensor. The Fresnel lens shall be designed to maintain Uniform Sensitivity Optics throughout the protection pattern, providing even coverage and detect ability throughout the coverage pattern, helping to detect an intruder at the edge of the protected area as easily as directly in front of the sensor. The detector[s] shall be provided with 2 lenses, a high security lens and a animal immune lens. Animal immunity shall be selectable, with either 0 lbs, 40 lbs, or 80 lbs options. High Security Lens details - The sensor and module combined shall construct a detection field 35 feet x 40 feet (11m x 12m), or 90o wide, with 44 zones of detection (22 long range, 12 intermediate, six lower, plus 4 look down zones). Animal Immune Lens details - The sensor and module combined shall construct a detection field 35 feet x 40 feet (11m x 12m), or 90o wide, with 102 zones of detection (44 long range, 36 intermediate, 18 lower, plus 4 look down zones).
The detector shall incorporate a selectable look down coverage pattern, which covers the area directly beneath the detector. The look down pattern shall use a 2 element mirror to project a minimum of 4 fingers in the area directly beneath the detector. The look down zones shall be optional, so that an installer can disable them in installations with pets, rodents or other animals that can get directly beneath the detector. MOUNTING HEIGHT: The detector[s] shall be capable of mounting at a height from 7’6” to 9’ [2.3-2.7m] without any adjustments, thereby minimizing possible installation errors.
PHYSICAL CHARACTERISTICS: The dimensional size of the detector shall be 4-3/8”H x 2-1/4”W x 11/2”D [11.2cm x 6.0 cm x 4.0 cm]. WEIGHT: The total weight of the unit shall be 3.3 oz. (90g). MODELS: The Intrusion Detector shall be model IS2535 (standard) with optional wall mount bracket SMB10, or tampered wall mount bracket SMB10T, or ceiling mount bracket SMB10C.
