3.3 PORTABLE EQUIPMENT CHARGING CIRCUIT <br /> <br />Two (2) additional 12 VDC circuits for charging portable battery powered devices, i.e. <br />Suction units, hand lights, defibrillators, portable radios, etc. shall be provided. These <br />circuits shall prevent discharge of chassis batteries by only permitting the charging of <br />portable devices when the vehicle is either running or the battery conditioner is <br />connected to shore power (operational). This implies that a battery conditioner is <br />required and may be specified in a different location within these detailed <br />specifications but is not necessarily being specified within this paragraph. A minimum <br />of 10-amp circuit breaker protection shall be provided for each circuit. These tagged, <br />identified leads shall be located, one (1) in the patient compartment and one (1) in <br />the vehicle cab. These leads shall not be connected to power nor shall they have any <br />connectors attached at either end. These circuits are intended for unspecified future <br />use. <br /> Y___N___ <br />3.4 SEQUENCER / LOAD MANAGER <br /> <br />To prevent excessive loading or load spikes on the electrical generating system at <br />system start up, a sequencer/load manager shall be integrated into the main circuit <br />board for stepped control of the main master emergency functions. The sequencer <br />shall sequence ON or OFF all master emergency functions at 0.5 second intervals. <br />The sequencer/load manager shall sequence specified loads ON, in the following <br />manner: <br />1. Body Warning Lights <br />2. Patient Compartment Dome Lights <br />3. Patient Compartment HVAC <br />4. Front Light Bar <br />5. Intersection and Grille Lights <br />6. Rear Light Bar- if installed <br />7. Wig-Wag Headlights- if installed <br /> <br />When a “low voltage” situation is detected, an audible alarm shall sound, and an <br />indicator light shall illuminate signaling the situation. When the vehicle transmission <br />is in PARK, the load manager shall shed emergency functions until the system <br />output voltage and the amperage draw of the systems still in operation equalize. <br />When in PARK and the vehicle PARK BRAKE is applied, the Stationary Elevated Idle <br />Control (SEIC) will activate to provide additional voltage for the system. If the “low <br />voltage”, 12.0 volts or lower persists, the sequencer/load manager shall initiate the <br />load shedding sequence at each 0.2-volt increment in the reverse order of these <br />emergency functions. <br /> <br />NOTE: Vital medical equipment such as suction aspirator system and/or electric <br />oxygen valve shall not be included in the load shedding sequence. These systems <br />shall remain powered until total failure of the electrical generating system occurs. <br /> Y___N___ <br /> <br /> <br />3.5 LOW VOLTAGE MONITORING SYSTEM <br /> <br />There shall be installed, as an integral function of the ambulance conversion main <br />power board, circuitry that continually monitors electrical system voltage. This <br />system shall activate an audible alarm and a steady burn red LED warning light to <br />indicate that system voltage has reached or fallen below 11.7 volts. There shall be <br />included a switch to deactivate the audible alarm. The audible alarm, LED indicator <br />light and the switch shall be located on an auxiliary control panel located in the
