SECURITY SYSTEMS
1. INTRUDER DETECTION
To detect unauthorised entry onto the scaffolding, the Permanex
electronic alarm lays an invisible wall of radio energy between
transmitter/receiver devices. These detector devices transmit an alarm
should a human intruder attempt to walk, climb or crawl through the
electronic energy field. The detectors are not affected by weather
elements, temperature extremes or vibrations i.e. traffic and have a
built-in protection device, eliminating outside interference.
2. OPERATING THE SYSTEM
The system is armed/disarmed from a control panel located within the
building/site office and is easily operated by a keypad. The control
panel indicates any break-in points on the scaffold and automatically
activates an audible alarm. It also features an audible and visual
tamper/fault indicator that is operational at all times even if the
system is disarmed. The Permanex system is supplied complete with
back-up batteries in event of a power failure.
3. SIRENS/ALARM/STROBE LIGHT
Combined electronic siren/strobe lights will be fitted to the scaffold
structure by our skilled technicians. All sirens are mounted in a
shatterproof casing with 24-hr circuit protection. The alarms only
activate in the area of intrusion, making fast intruder location
possible. The Permanex system automatically cuts out and re-arms itself
following an alarm.
4. WARNING SIGNS
Prominently located on the scaffold will be Permanex Security notices.
5. LOCATION
Detectors will be positioned at first floor level of windows breached by
the scaffold i.e. first floor of building or first scaffold lift.
6. EVENT LOGGING
All intrusion and tamper events are logged against time in an electronic
memory, which cannot be cleared. A printout of these events is also
provided.
SCAFFOLD SECURITY SYSTEM - EQUIPMENT AND SPECIFICATION
1. GUARDALL - FENCEGUARD MICROWAVE BEAM
Outdoor Microwave intruder detectors
Range - 10 metres to 200 metres
Elliptical (cigar shaped) beam - designed to provide greater sensitivity
in the horizontal plane
Sensitivity - Five alternative sensitivity settings, selectable on site
Signal Processing - minimises false alarms from environmental changes
(fog, heavy rain, snow, sleet etc.) and from birds or small animals
entering the detection zone
Four Modulation Channels - ensuring that links do not interfere with
each other also making highly resistant to electronic countermeasures
2. OPTEX LX 40 AND LX 80 - PASSIVE INFRA RED DETECTORS
Detection method - passive infra red beam
Detection area - 12m x 15m x 120 Wide, 24m x 2m Long
LED indicator
Alarm output and Tamper switch
Photocell adjustment
3. PULNIX PB 50 HF'S 50M -200M - "INTELLIGENT QUAD PHOTOELECTRIC BEAM"
Four synchronised beams - 4 beams are "and-gated" helping prevent false
alarms from flying debris or animals.
High powered infra red - The active infrared is exceptionally strong
with a maximum arrival distance ten times greater than the specified
protection distance.
Four frequency selections - 4 separate choices of frequency avoids cross
talk in stacked or long linear installations, allowing stacking of
Transmitters or Receivers all on one side.
Beam transmission strength selection - 2 levels of beam transmission
strength can be used to set the transmission distance.
Auto- gain lock - Optimal sensitivity gain is set at any coverage
distance up to the maximum protection distance.
Environmental module - Environmental trouble signal is sent when beam
reception is reduced below an acceptable level.
Programmed AGC function - Sensitivity is automatically increased in bad
weather to contend with fog, rain or frost.
Alarm memory indicator - Alarm memory LED located on Receiver can be
manually reset or remotely controlled via panel.
Audible signal alignment - An alignment tone aids quick set-up of beams
for electrical measurement of alignment
Other features - Monitor output, response time changeover, tamper output
4. MENVIER TS900
All events recorded showing time, date and cause of alarm signal
10-56 Programmable zones
4 keypad types
700-1,800 event log
31 user codes
Extended format reporting - printer read out
Sequential alarm verification
Downloading
System diagnostics
Alarm abort & Remote reset
5. CITADEL - INTEGRATED SOUNDER & STROBE UNIT
Sounder Output 118 dBA
Strobe flash rate 80-140 per minute
Anti - tamper operating mode
Dual fail-safe cut-off timer
Twin status indicators
Battery charge indicator
Blue Strobe/Lens colour
6. OPTEX BX-100PLUS
Outdoor 100ft (30 m)
Detection Method - simultaneous interruption of 2 infrared beams
Beam Characteristics - Pulsed Infrared
Interruption Period - 50 msec
Tamper
Operating Temperature - -30F to 131F (-35C to 55C)
Full Time Relays
Alignment with Visual and Audible Indicator
Light Reduction Filter
High resistance to false alarm through Fog, Rain etc.
7. OPTEX VX-40
Passive Infrared
Range 12 m (40ft) 90 degree wide
14 Zones
Twin beam detection pattern
Detection range reduces false alarms due to unwanted movement, cars etc
Size Judging Function
Bright Light Disturbance Immunity
Note: The Optex VX40 and BX100 are used in combination to protect end
stops of scaffold. This combination cannot be swivelled out of alignment
due to the beams.
8. MONITORING OF SECURITY SYSTEM
Response to Central Control Station - optional
Response to pager
Response via dedicated standard phone line
Response via Dualcom System
Response via GSM network
Response to nominated keyholders
Response to Alarm only
Response to combination of above or other agreed protocol
24 Hour call out by specialist engineer.
