The 14V is an omnidirectional electromechanical siren that is produced by Sentry Siren, Inc. It is the largest and most powerful of Sentry's single rotor sirens, being little more than a 40V2T cut in half. It is intended for longer range use than its single rotor contemporaries.
History and design
14V
The 14V is one of Sentry's newest sirens, being introduced in 2015. It replaced Sentry's 10V as the largest single rotor siren upon its introduction and is quite unique compared to the rest of Sentry's lineup. The 14V is essentially a Sentry 40V2T that has been cut in half, using the same 10-port single tone rotor and stator as the lower half of a 40V2T. It is driven by a 15 hp AC motor, which is available only in three phase power. It has the distinction of being the only 10-port single tone siren sold on the US siren market today.
Like all of Sentry's single rotor sirens, the siren's design is very basic, with the rotor and stator being attached to a 6-legged mount which has a cone to project the sound from the intake outwards. The motor itself is placed inside a weatherproof housing above the siren. This simple design allows the siren to be both cheap and easy to maintain. The horns and intake use mesh screens to keep debris out. The siren comes standard with 5 large horns, of which 2 stator ports are shared. These are the same horns used on the 40V2T. The siren can be ordered with a skirt instead of horns if the customer desires.
14V-B
The 14V is also available in DC power, in the form of the 14V-B. The 14V-B uses a 14 hp 72 V DC motor instead of a 15 hp AC motor, which allows for the siren to make use of battery backup if AC power is lost. The siren is rated to run approximately 30 minutes before running out of power when running on its batteries. The 14V-B is otherwise identical to the standard 14V in both performance and design, with the only difference being the tag, nonlinear windup, and the addition of the battery enclosure next to the controls. 14V-B units are often set to run at only 3,000 RPM instead of the standard 3,500 RPM, which causes their pitch to be similar to an 8-port Sentry, with a significant reduction in sound output. The reasoning for this is unknown, but may be to save on battery life.
