Hikvision AX Hybrid Pro Control Panel | DS-PHA48-EP(B)
The Hikvision DS-PHA48-EP(B) is an AX Hybrid Pro intrusion alarm control panel: a wired panel that can also work with wireless detectors and peripherals. It has 8 on-board zones expandable to 48 in total, 16 areas, and reports alarms over LAN, PSTN, GPRS or 3G/4G.

Key Features
Hybrid Wired and Wireless System: 8 on-board zones plus 40 expandable wired/wireless zones, and 4 on-board outputs (2 relay outputs and 2 I/O outputs) expandable with 44 wired/wireless outputs. End-of-line resistors of 1K, 2.2K, 4.7K, 5.6K, 6.8K and 8.2K are supported, which helps on sites with existing alarm cabling.
Dual-Path Communication: Alarm events and other signals are sent over LAN, PSTN, GPRS or 3G/4G using a main and a backup channel with configurable priority, so one failed link does not cut the panel off. The GPRS and 3G/4G modules are optional.

Video Verification and Speed-X Bus: 2-channel on-board IP camera video verification records 5 s pre-alarm + 2 s post-alarm (or 2 s + 5 s) clips for the alarm receiving email or mobile client. One Speed-X bus carries verification video or pictures from PIR-CAM detectors (max. 4 wired PIRCAM).
Flexible Arming and Notifications: Arm and disarm by keypad, keyfob, mobile client, iVMS-4200, SMS or tag. Alarm notifications are pushed by message and through Hik-Connect, and 1 customized voice library can be uploaded and played in alarm phone calls.
Mains Power with Battery Backup: Powered from 100 to 240 VAC through an on-board transformer, with support for a 12 V 7 Ah lead-acid backup battery for up to 36 hours.
Who it's for / Works with
It works with Hik-ProConnect, Hik-Connect, Hik IP Receiver, Hik IP Receiver Pro and Hik-Central. Hikvision lists markets, hotels, supermarkets, warehouses, offices and houses (especially with pre-installed cables) as typical sites.
Good to know
- The backup battery (12 V 7 Ah) is not included.
- GPRS and 3G/4G communication need an optional module; SMS also needs one of these modules.
- This model has no Wi-Fi interface listed in its datasheet; it connects by Ethernet.
- Operating temperature is -10 °C to 40 °C.
