SYNOPSIS
This Procurement Specification defines a DUAL BATTERY DRIVEN - HYDRAULIC POWER SYSTEM configured specifically to operate BARRICADE SYSTEMS manufactured by DELTA SCIENTIFIC CORPORATION. These include DELTA Models DSC900, DSC1100, IP500, TT212, TT212E, TT212EC, TW2015, TW4030, DSC7000 and others.
DELTA Barricade Systems destined for permanent or temporary installations at locations where local power is unavailable or unreliable can be powered by this Hydraulic System. The Barricade System is operated from a Local Control Panel which can be permanently mounted or operated as a ‘walk around’ hand-held control point utilizing an umbilical cord connection.
The high energy; deep discharge, rechargeable batteries used in these systems can be maintained at specified operating rates by either a built-in battery charger and/or a solar panel array. The battery charger operates on a standard utility source – the solar panel array is provided with a mounting stand and interconnecting cable.
As an option, Battery Booster Packs in self-contained all-weather cases can be ordered. Booster Packs are charged off site and can be plugged into the system as the primary source of power or to supplement a standard Battery and its charging systems.
Existing DELTA Manual Barricade Systems can be retrofitted for full powered operation with this unit.
With the H8050 a Barrier system can be operated at a rate between 10 and 15 seconds for a full up-down cycle. Depending on available recharging employed, the sustained rates of 60 cycles per hour can be maintained indefinitely. With the battery charger and solar array deactivated, a fully charged battery can typically provide in excess of 200 full operating cycles
As an option the Battery Driven – Hydraulic Power System can be furnished with a hand operated rotary pump for manual operation of the interconnected barricade system.

1.5.2Recharging Rate: The Solar Array shall be sized so that for each standard solar day (defined as 5 hours continuous sunlight) the Barricade system can be operated 30 full cycles without depleting the overall battery charge level. (Optionally available – Solar Array with capacity to operate 60 full cycles without depleting the overall battery charge level)
The Solar Array shall be provided with a mounting post and frame for local placement or mounting. An interconnecting electric cable 10 feet long shall be provided.
1.5.2.1.Booster Battery Pack (Optionally available): Field interchangeable rechargeable battery pack can be used independently or in parallel with the internal battery.
1.5.2.2.The System shall be supplied with _____(customer specified) Booster Battery Packs.
1.5.2.3.When fully charged the Booster Battery Pack will independently operate the Barrier 50 full cycles without recharging.

Each Battery Pack shall have Indicators showing battery status and condition.
- EXTENDED OPERATING OPTIONS
2.1.The System shall be provided with internal circuitry so that other sources of external power can be used to supplement the internal battery. These conditions could include the need to operate the system at higher throughput rates or for faster recharging the internal battery.
2.2.External power connection points shall be provided on the Power Unit to facilitate connecting a range of external power sources. These include standard 12V automobile batteries with jumpers, DC power takeoffs, standard vehicle cigarette lighter ports, the output of auxiliary engine generators, or the output of motor vehicle generators directly.
- MANUAL OPERATION – HAND CRANKED PUMP (Optionally Available)
3.1.A manual pump system shall be incorporated in the System so as to be available for independent use or to operate in parallel with the Battery Driven Hydraulic Power Unit.
- CONTROLS - The following control shall be furnished:
4.1.Control Circuit: A control circuit shall be provided to operate the H8050 Power Unit to open and close the Barricade(s).
4.2.This circuit shall contain all relays, timers and other devices necessary for the Barrier operation.

- ENVIRONMENTAL CONSIDERATION
5.1.Operating Temperature Range: 10 to 115º F.
5.2.All specification values herein are based on a new battery operating in a temperature range of 50 to 115ºF
Note: As the internal temperature of a battery is reduced there is a change in its operating characteristics. At 32ºF a typical battery will develop approximately 65% of its capacity. As a battery ages, there is some decrease in overall performance.

6.3.Dimensions: Principle dimensions shall be checked against drawings and ordering information.
6.4.Finish: Coatings shall be checked against ordering information and shall be workmanlike in appearance.
- PREPARATION FOR SHIPMENT
7.1The System shall be crated or mounted on skids as necessary to prevent damage from handling. The shipping container(s) shall be of sufficient structural integrity to enable the assembly to be lifted and transported without failure.
- DISCLAIMER
8.1.Please note - careful consideration must be devoted to the selection, placement and design of a Vehicle Barrier. Just as in the case of any traffic system, perimeter security device or security gate that blocks a roadway or drive, care must be taken to ensure that approaching vehicles as well as pedestrians are fully aware of the Barriers and their operation. Proper illumination, clearly worded warning signs, auxiliary devices such as semaphore gates, stop-go signal lights, audible warning devices, speed bumps, flashing lights, beacons, etc. should be considered. Delta has information available on many such auxiliary safety equipment not specifically listed herein. It is strongly recommended that an architect and/or a traffic and/or safety engineer be consulted prior to installation of a Barricade system. Delta will offer all possible assistance in designing the operating equipment, controls and the overall system but we are not qualified nor do we purport to offer either traffic or safety engineering information.
