As part of our on-going research and development programme our R&D department has given the Pertronic F1 single zone conventional fire alarm an internal make-over. The revamped panel now comes standard with Fire and Defect relays, allowing, for example, connection with a security system for remote monitoring.
The Fire relay can be isolated using an internal switch, to prevent accidental false alarms during maintenance. The door interlock system monitors the state of this switch and sounds a piezo buzzer if the cabinet door is closed with the Fire relay isolated. The Fire relay is normally de-energised with a closed contact. When a fire condition occurs, the relay energises and opens the contact. The Defect relay is normally energised with a closed contact. This relay drops out if the panel detects a defect or the power fails, as required by NZS4512. Note, however, that the F1 panel does not provide an SGD output.
Also new on the F1, a booster supply increases the zone voltage to 20 Volts, with datum levels identical to the F4 panel. The F1 panel is now able to support forty smoke detectors.
The revamped F1 fire alarm control panel is a drop-in replacement for older F1 panels on existing systems.
