Pearl™ Intelligent addressable fire alarm control panel
Data Sheet
Pearl – Simply more intelligent
The Pearl fire alarm control panel from Notifier by Honeywell is a robust and easy to use networkable 1 or 2 loop panel. It exploits Notifier’s class leading Opal digital protocol to maximise the speed and efficiency of fire detection and alarm.
The large display with its intuitive interface and menu driven features allows quick and easy operation of the system.
Coupled with more power and devices on the loop than other panels in its class, the simple design will allow for trouble-free first fix installation.
Compatible with the ID2net network used by the ID3000, the Pearl panel is supported by an integrated tools suite to enhance and simplify the system management.
Extended capacity
- The Pearl supports up to 636 loop devices (159 detectors plus 159 modules per loop)
- Longer loops, but fewer of them, give the opportunity to save on installation time, cost and wiring
- Highly resilient Opal system, able to pinpoint a loop fault whilst maintaining full system operation
- Powerful networking capability – Up to 16 Pearl panels, controlling over 10,000 devices, can be networked via the superfast ID2net; prioritising a fire signal to communicate across a network in under three seconds

Ease of use
- Intuitive on-site management – backlit buttons for fast, error free situation management, and large display giving complete information at a glance
- Simpler diagnostics and maintenance – panel control of detector LEDs enabling confirmation of detector status
- Text programming via MS Excel spreadsheet
- User permissions set per individual password
Flexibility
- Unique first fix bracket with adaptations for 19” rack or flush mounting.
- Fast system set up and commissioning via the panel, loop “Autolearn” and advanced PC tools suite
- Comprehensive “Cause & Effect” programming capability
- Panel sounder and beacon synchronisation
- System extensions and adaptations can be made quickly without compromising fire cover and without extensive re-cabling
- Separate text change without risk to “Cause & Effect” or system configuration.
- Ability to run BS5839 pt 6 system for HMO

Mounting Options
The Pearl’s innovative mounting system gives the installer easier access to terminate wiring to the back plate before the panel is even installed. Various mounting options are available to allow for larger battery capacity for longer standby time and to enable flush mounting of the panel.

Innovative first fix bracket
- The first fix bracket can be fixed easily in position using the supplied template.
- Cables can be terminated through the top entry holes in the bracket.
- The Pearl can then be fitted easily onto the first fix bracket and secured using 4 screws.
Extension Box
The PRL-BOX extended enclosure enables the installation of 38Ah batteries.

19 inch rack mount kit
The PRL-RM19 rack mount kit enables the Pearl to be mounted in a 19 inch rack.

Flush Mounting Dress Ring
The PRL-BEZEL Flush Mount Dress Ring offers a practical way of flush mounting the Pearl panel.
It is designed for use in combination with the rack mount kit and is available as a stand a lone part if required.
