Product Overview

The OZH4800E control panel is an analog addressable fire alarm panel using the latest 32 bit microprocessor technology and
containing 2, 4, 6 or 8 SLC loops with each loop supporting 192 devices of any combination (sensors or
Communication between devices is transferred through standard cable
(shielded or twisted pair is not required). Each panel includes a 5.0 amp power supply,
600 characters LCD display, 29 large easy-to-use tactile touchpad for system
operation, programming and maintenance, 12 state indicators and a RS232/RS485
communication port. System operations include silencing alarms and troubles,
resetting system and manual starting/stopping field equipment. The system’s non-
volatile event history buffer stores 9999 events for viewing. The system supports a
variety of Orena devices: smoke and heat sensors, manual call points, contact input
(monitor) modules, relay output modules, dual input/output modules, and short circuit
isolator modules. In addition, interfaces to conventional detection systems can be
established by using a conventional zone-monitoring module. The basic system can be
expanded by adding OZF-LCD remote annunciator, OZH48ZL signalling line circuit
expander, and optional mini-printer (for printing system reports). The intelligent panel
and detectors know the difference between a fire and a dirty sensor. It lets you tailor
sensor sensitivity and gives you immediate, pinpoint accuracy for any condition. The
powerful OZH4800E system provides you with revolutionary value and performance in
addressable sensing technology, reduces nuisance alarms and makes service calls a rarity.
