HUNTER-PRO Series Installation Guide 11
• A model can be expanded to its limit number of zones and
users. For example, Hunter-Pro 896 cannot be expanded to
97 zones or 97 users
• The EPROM version and the system’s software version must
match, or a ‘System Error’ is displayed. For example, the
Hunter-Pro 896 EPROM cannot be used with a Hunter-Pro
832 software
1.6.2 Fuses
F5A - protects the PCB and the battery from high current (Thermo 5A/250VAC)
F6 - protects the PCB from an AC short (Fast 3.15A/250 V
1.6.2.1 Thermal Fuses to limit current:
F1 – Detectors power supply (750mA)
F2, F3 – Siren 1 and Siren 2 (1.1A)
F4 – Keypad power supply (750mA)
F7 – Radio transmitter protection (200mA)
1.6.3 Connections & Terminals
1 AC: Voltage Input
14VAC input supplied by a transformer
2 “+”, “-“: Connections to backup Battery
Red wire: “+” (positive) contact of the battery
Black wire: “-” (negative) contact of the battery
Connecting the battery inverted will damage the PCB
3 Z1–Z8: Zones terminals
Eight zone terminals for connecting dry contact detectors. Each zone can be protected
by a single or double EOL resistors (refer to “Connecting Zones”, section 3.1)
4 (+): Power Supply for DC Detectors
12V power supply for DC detectors: infrared, ultrasonic, beam etc.
5 KEY input
An input for momentary or on/off keys or Key fob for arming/disarming the panel
6 Ext., Int.: External & Internal Sirens terminals
Dedicated automatic thermal fuses (F2 and F3) for the sirens (see section 3.6)
7 RELAY output
An onboard relay that can be triggered in response to alarm/event and via telephone or
remote control
