Siren Installation & Safety

 

A certified electrician with knowledge in electro-mechanics should perform PAKITA siren installation.

Manipulate siren with caution. The technician who install or perform a maintenance service on the siren should always wear some protective equipment (gloves, helmet, goggles, and ear protection).

Lift up Siren

To lift it up, use all four rings from the siren elevating base as shown on the schematic presented here below. Use preferably some textile slinging devices. In any cases, protect the head of the siren.

Caution: The small rings localized on the horns of DS sirens should not be used to raise siren up, but to only facilitate horn holding.

Siren Installation on High Sites or Valleys recommended

For installation in valleys, or high sites are recommended; for installation in non-flat areas, it is recommended to install the siren on a high site in the valley. In any cases, immediate siren surroundings must be cleared of any screen, as much as possible. In some cases, the use of an elevating base or a pole could be used.

 

When positioned on heights, it is advised to protect sirens against lightning. 

Common cautions concerning civil protection of individuals should be taken for persons who are in proximity of sirens. Auditory risk or accidental burst risk have to be avoided. It is then mandatory to keep a safe security zone around the siren (See the decibels scale below on this document). To normalize siren installation, the customer should contact an accredited office (Architect offices, AINF, Firefighter offices, Social security offices, etc.)

Maintenance

In the necessity of a maintenance service, everything should be done in order that the siren is turned off (Respect of maintenance procedures, controls locking, securely padlocked control box, proximity shut off switch).

 

A monthly test is recommended for an alarm check-up. Numbers of administrative offices recommend these security rules to alleviate the number of unexpected breakdown.

The check-up of electrical lines, contactors, grounding and masses/phases of the motor have to be performed periodically. Siren should also be cleaned regularly and the exterior coating renewed when necessary. Siren sealing, horn fixtures and anti-bird grids should be regularly checked.

If after a check-up, an electrical or mechanical problem inherent to the siren is detected, the siren should be sent to a specialized workshop for maintenance or repair.

Siren Positioning

For reasons of water streaming and sound ranges, it is advised to place the siren in an upright position, siren head on top on a flat surface (“fungus position”). The siren sealing onto the floor has to be done on a foundation that is free of vibration, e.g. concrete or metallic-based floors. The fixture of the siren on this surface is usually performed using a sealing thick tar felt vibration-proof and rot-resistant rubber. Do not forget to use lock-bolts for the sealing in order to avoid any loosening.

CAUTION : Double check that the turbine (or stator) is not blocked and that it is freely rotating in its housing before turning on the motor.

Hearing openings of sirens should always be mounted either with anti-bird grids or sound amplifier horns equipped with anti-bird grids.

Siren Plugging

The plugging is identical to the one from a classical electrical asynchronous motor. It is important to note the siren rotation direction, which is indicated by an arrow on the head siren hood (LM, LC, DS types).

For security reasons, it is reminded that, it is strictly forbidden to plug in an electronic speed regulator or a frequency converter in order to plug in the siren electrical motor without the agreement of an accredited office.

NOTE: Caution to any tension drop. Measure the voltage of the arriving electric current at the siren motor terminals. Check as well the grounding.

Siren Grounding

Caution, do not forget to ground the system.

 

NOTE: For Single-phased motors, please, do read information found in the motor terminal box.

Safety

A Siren can only be used to alert population. Other usages are forbidden.

To practice siren drills, a monthly test is recommended to prevent any unexpected break-down.
