3.8 INTERCOM SYSTEM <br /> <br />A pre-wire shall be done with Department provided cables for a headset intercom <br />system. This must be verified by SBFD representative prior to installation. <br /> Y___N___ <br />3.8.1 Two (2) 22-gauge 9 wire cable shall be installed from the forward area of the <br />overhead squad bench cabinet to under the chassis radio/siren console. <br /> Y___N___ <br />3.9 BATTERIES <br /> <br />There shall be three (3) matching "No Maintenance" 12-volt batteries. They shall <br />total not less than 2,700 CCA with 180 minutes of reserve capacity. The batteries <br />shall be located in the OEM location under the driver step, below cab door, in a tray. <br />Add on step shall not hinder battery access. <br /> Y___N___ <br />3.10 SEAT BASE INTERNAL 12 VOLT DC POWER <br /> <br />For certain standard internal 12-volt DC power circuits, there shall be circuit <br />protection provided by the use of manual reset breakers mounted in the outboard <br />panel of the driver's seat base. Potter & Brumfield 12 VDC breakers shall separately <br />protect the Radio Power circuit with a 40-amp breaker; the Constant Power circuit <br />with a 20-amp breaker; the Ford auto-throttle system with a 10-amp breaker; and the <br />Isolator circuit for the two (2) additional 12 VDC charging circuits required in 21-02- <br />00, a 20-amp breaker. Due to the potential danger associated with a separate <br />"battery hot" circuit, no exceptions to the above will be allowed. This Isolator circuit <br />includes a "low voltage" Schottky Diode to isolate medical equipment batteries from <br />any electrical loads. The diode shall be located and electrically connected between <br />the circuit breaker and the receptacles. Additional breakers may be added for <br />optional equipment such as power door locks, multiple radio installations or <br />compressor pumps. Additional radio leads including hot wire, ignition switched hot <br />wire and ground shall be provided. One set shall be in the front console and one set <br />in the rear action area. Each power lead shall have a 30-amp circuit breaker and <br />include one 12-volt hotwire and fuse holder with 30 amp. <br /> Y___N___ <br />3.11 POWER OUTLETS <br /> <br />Two (2) 12-volt power point style outlets shall be installed. One (1) shall be provided <br />in the forward section of the primary action area, above the countertop and one (1) in <br />the upper section of the ALS cabinet. <br /> Y___N___ <br />3.12 115 VOLT AC POWER <br /> <br />There shall be 115-volt AC wiring furnished. A three-wire system is used for <br />powering medical equipment, battery charger, etc. This electrical system, including <br />wiring and associated equipment, shall comply with AMD STD 009, 120V AC <br />Electrical Systems. The system shall incorporate a hospital grade GFI (Ground Fault <br />Interrupt) device with a 20-amp circuit breaker that can also be used as a disconnect <br />switch for the interior 115-volt outlets. The GFI device shall be located on the street <br />side in the action area. When an inverter is specified, an automatic transfer switch <br />shall be furnished which will automatically turn off the inverter 115-volt supply when <br />the 115-volt utility shoreline power is applied. <br /> Y___N___ <br /> <br /> <br />3.13 INVERTER
