SRN-2000 SERIES
Professional All Purpose PIR Detectors
1. INTRODUCTION
1.1 Applications
The SRN-2000 is the only universal PIR you can truly standardize on
without compromising. It combines several different design techniques
to master the industry's biggest problem - false alarms.
An outstanding variety of 45 easy-to-change lenses is available for the
SRN-2000 from the "Super Red Lens Library":
• 9 wide-angle lenses up to 140° • 3 long-range corridors up to 36 m
(120 ft) • 6 pet alleys • 3 finger curtains • 8 lenses for combined ceiling
and room coverage • 10 unique lenses for multiple 2-3 room and
corridor coverage • 6 solid curtains.
The "Super-Red Lens Library" provides the most extensive selection of
coverages and saves you time and money in every installation.
1.2 Features
Incomparable Flexibility:
• 30° Vertical and Horizontal Adjustments
• 0-5 m (0-17 ft) Installation Height
• Visible Pattern Locator
• Surface, Corner and Flush Mounting

3. MODELS AND LENSES
3.1 Super Red SRN-2000 Models
SRN-2000: Standard model, with pulse counter.
SRN-2000H: Horizontally mounted PIR provides the largest solid curtain
coverage 18 x 18 m (60 x 60 ft) and five interchangeable lenses (see
Lens Library).
SRN-2000R: Ceiling mounted PIR provides maximum 6 x 18m (20 x 60
ft) floor coverage when mounted at 6 m (20 ft) height.
SRN-2000M: Similar to SRN-2000, but with additional alarm latching
memory for multiple PIR installation on a single zone.
SRN-2000C/PC: 9 Volt battery-operated PIR, providing the lowest
standby current drain - 0.004 mA. Has a pulse counter and is designed
to operate with virtually all wireless transmitters on the market.
SRN-2000CH: Horizontally mounted, battery-operated PIR, providing
same solid curtain patterns as SRN-2000H.
SRN-2000CR: Ceiling mounted, battery-operated PIR, with the same
coverage pattern as SRN-2000R.
SRN-2000W/PCN: Self-contained fully supervised wireless PIR, with
built-in RF transmitter.

Installation Instructions

• Switchable Walk-Test Indicator
• N.C. Silent Relay
• Tamper Switch
• Low Current Drain: 17 mA
• 9-16 VDC Supply Voltage
False Alarm Immunity:
Programmable Pulse Counter - to virtually
•
eliminate environmental disturbances
• Adjustable Coverage Range - to adjust
coverage range to room size
• Unprecedented RF Immunity - rejects RF
interference up to 1000 MHz
Light Rejection Filter - rejects visible light
•
variations
• Maskable Lens Patterns - to block thermal disturbances
• Test-Point - to identify and eliminate background disturbances
• Dual-Element Low-Noise Pyroelectric Detector - rejects thermal
variations with maximum signal-to-noise ratio.
Additional features are available with other models (see Para. 3.1).
Coverage-Range Control: Adjustable from 100% to 50% of the
nominal lens coverage range.
Pulse Counter: Programmable to 1, 2 or 3 pulses with self-adjusting
walk-test override.
MOUNTING
Wall or corner mounting. Optional bracket SRF-201 for flush mounting.
ENVIRONMENTAL
°

3.2 Lens Selection
Coverage: Lens # 100 is the standard
pattern supplied with SRN-2000
sensors (not applicable to models SRN-
2000H, R, CH, CR).
Printed circuit board elevation scale is
°
factory preset at -5 . For application of
PCB elevation scale, see Table 1.
Lens No. 100 Specifications
Total Number of Beams: 38
3 Layers: Upper, Intermediate and
Downward. Upper Layer - 9 twin
beams, optically split to 18 beams.
Intermediate Layer - 5 twin beams
(split), angled 10° below upper layer
Downward Layer - 5 twin beams
(split), angled 25° below upper layer.
Angle span: 90° Wide Angle.
Coverage: Max. 18 x 18 m (60 x 60 ft).
If the standard No. 100 lens does not meet your coverage needs, select
the desired pattern from the SUPER RED LENS LIBRARY. Your
nearest distributor will be glad to supply you with any lens you choose.
