HFP
HFP analogue addressable fire panel family (HFP AP-AS single/two loop panels and HFP multi-loop panels, listed separately). It appeared in Hochiki Europe's Systems Catalogue but is not listed on Hochiki Europe's current site; no withdrawal notice was found, so its status is unknown.
Control PanelSource-checked
HFP AP-AS Single/Two Loop Panel
Single or two loop analogue addressable fire control panel using Hochiki ESP loop drivers, networkable with HFP multi-loop panels and repeaters. A single-loop HFP AP-ASL version omits the second loop, printer output, networking, I/O boards and the HFP AP-CRL repeater. No longer listed on Hochiki Europe's current website (October 2026); no withdrawal notice found.
Control PanelSource-checked
HFP Multi Loop Analogue Addressable Panel
Multi-loop analogue addressable fire control panel range using Hochiki ESP loop drivers, networked with HFP AP-AS panels and repeaters over the fault-tolerant HFP network (secure loop or open-ended topology). The catalogue does not state the maximum loop count. No longer listed on Hochiki Europe's current website (October 2026); no withdrawal notice found.

Hochiki HFP AP-1AS/2AS • Double address (fault announced at loop initialisation)HFP AP: Double address faultPer the manual, the control panel can detect devices set to the same address and will announce a “Double address” fault if it finds any. It cannot tell which devices are double addressed. To help find them, go to access level 2, choose the view devices option, view devices by loop, and check that all the expected devices are listed. If there is one double address fault and one device missing from the expected list, it is fairly certain that the missing one is the one addressed incorrectly. With more than two devices on one address, or more than one double address, use a process of elimination. If a heavily populated loop is disconnected the panel reports all devices disconnected; after reconnection it can be quicker to restart the panel with the Reset switch.Hochiki HFP AP-1AS/2AS • Fault events are non-latching (Reset does not clear them)HFP AP: fault events are non-latchingPer the user manual, the Reset button is used to reset any activation defined as a latching input type, which includes fire and pre-alarm events. In general, fault events are non-latching and cannot be cleared by operation of the Reset button: these events clear when the fault input is cleared.Hochiki HFP AP-1AS/2AS • General FaultHFP AP: General FaultThe yellow General Fault LED flashes when there is a fault on the system. Other fault LED indications may also be present to identify the nature of the fault. The Fault Contact energises and the panel buzzer sounds continuously; details of the fault are shown in the LCD text display. From the official Hochiki Europe HFP AP-1AS/2AS User Manual, section 3.1 (front-panel LED indicators) and section 4.2 (Fault Event). This is a User Manual, not the fuller Product/Installation Manual, so it names the indicator and the general behaviour but not every underlying wiring-level cause.Hochiki HFP AP-1AS/2AS • Loop open circuit or short circuit (how the panel responds)HFP AP: loop open or short circuitPer the manual, power is driven from the LOOP OUT terminals and returned to the LOOP IN terminals, where it is monitored for loop continuity. If the loop is open circuit (a cable fault, or a short circuit isolator operated), the panel drives power from both LOOP OUT and LOOP IN, so that despite a single break or short all devices stay connected. In the case of a short circuit, the short circuit isolators isolate the faulty section and the panel reports the devices between the isolators as missing. Both LOOP OUT and LOOP IN connections have short circuit isolation, so a short between those terminals and the first isolator is isolated too. Isolators must be fitted so that a single short or interruption will not prevent the indication of a fire alarm from more than 32 detectors and/or manual call points.Hochiki HFP AP-1AS/2AS • Sounder Fault / DisabledHFP AP: Sounder Fault / DisabledCombined fault/disablement LED for sounder outputs. Illuminates if a sounder output fault is present, and also illuminates (with the General Disablement indicator) when sounder outputs are deliberately disabled via the Access 2 'Disable Sounders' menu option. From the official Hochiki Europe HFP AP-1AS/2AS User Manual, section 3.1 (front-panel LED indicators) and section 4.2 (Fault Event). This is a User Manual, not the fuller Product/Installation Manual, so it names the indicator and the general behaviour but not every underlying wiring-level cause.Hochiki HFP AP-1AS/2AS • System fault message after a PC configuration downloadHFP AP: system fault message after downloadPer the manual, after a configuration is sent back to the panel from the PC (write enable on, then synchronise), the panel shows RECEIVING NEW CONFIGURATION, PLEASE WAIT during the transfer and then the start-up screens. When the transfer has finished, switch the write enable switch off, enter access level 2 and press the front panel reset button to clear the system fault message. The panel then contains the modified configuration.
