| Provides Voltage Protection During Engine Start The abrupt DC system voltage drop that accompanies engine starting can cause microprocessor-based voice and data transmitters to “dump” programmed memory. StartGuard solves this problem by providing supplemental voltage to sensitive electronics while the engine is cranked. It contains a sealed rechargeable battery which is switched on-line to electronics when the starter switch or solenoid is engaged. When the engine is running StartGuard automatically goes off-lineand the internal battery is recharged by the alternator. |

NAV-PAC™
|
Mobile communication electronics such as programmable two-way radio and data transceivers, vehicle location systems and other microprocessor-controlled devices require clean and steady DC input power. Their sensitive circuitry is highly vulnerable to voltage drop from engine start, noise and line spikes from alternators and motors, and conducted noise from various other electronic devices. NAV-PAC prevents all of these problems. • Prevents voltage “drop-out” during engine start • Absorbs line "spikes" • Filters out electrical interference • Provides supplemental voltage/battery back-up for up to 15 min. • Remote monitor panel provided |
 |
NAV-PAC has been successfully employed for years by thousands
of Fire Trucks and other Emergency Service vehicles nationwide
