The Whelen Park-Kill Module is a relay type device. Proper installation of this unit will allow the operator of a vehicle to activate or deactivate a desired emergency response device, such as a siren, via the transmission park neutral safety switch. There are several ways to install this module, depending upon how and what the operator wants to activate or deactivate when the transmission is in park. This relay has a maximum switching current of 30 Amps.
The Whelen Park-Kill Module is most commonly used in conjunction with either the MPC01 and MPC02 Multi-Purpose Controllers, or the 295 Series siren amplifiers, but could be used to activate or deactivate any load under 30 amps.
