1. Introduction
Electro Detectors has been manufacturing radio fire alarm systems since 1987 and with the introduction of a harmonised specification for
Europe has now complemented its range of products to meet EN54 Part 25. Based on the popular Zerio system, it has been designed to be
capable of handling 240 devices in 20 zones. Typical installations would include small offices, private houses, HMO’s, guest-houses and
small hotels.
The system has been designed to allow very simple set up with most operations being automated and is capable of displaying full text and
having sophisticated cause and effect programming.
The panel requires a single 7.0Ahr Lead Acid battery to achieve 72 hours standby. If wired booster panels or other ancillary equipment is
connected to the system then care should be taken to ensure that the standby battery time is not effected. See appendix
Devices for the system are visually the same as the standard Millennium devices but are labelled differently with a blue label. These
devices are not compatible with the Millennium or Zerio range of fire alarm equipment.
A memory module is plugged into the processor board. This stores a copy of any set-up information including device text and cause and
effects. This can be used as a means of swapping data between panels should the need arise.
In order to program and log devices into the system, the system uses a radio interface. A cable is no longer needed with the Zerio Plus
system. The system also stores the data programmed into each device allowing replacement devices to be easily cloned onto the system.
Prior to installation, the building where the system is to be installed must be surveyed to ensure that each device to be fitted has a good
radio communication path to the control or booster panel . If this is not done correctly the system will operate unreliably.
When installing devices, they must be positioned as per the survey. Installing a device even a few inches from the surveyed position can
reduce the signal strength significantly, especially if any metal work is contained in the ceiling above the new position (e.g. air-
conditioning ducting).
When manufactured, each device is programmed with a unique ID. Whenever a device transmits a message this ID is included as part of
the message. Also included in the message is the status (i.e. alarm condition, unit removal, low battery etc). The amount of smoke inside
the head at the time of the transmission is included as part of the message. Even if there is no change in status, the device will transmit an
‘I’m OK’ verify message approximately every 60 seconds. If these transmissions are not received from the device within the verify
period (typically 400 seconds) then a ‘Verify Fail’ fault is generated.
IMPORTANT
Failure to perform an accurate survey will result in the system being unlikely to function correctly.
These errors can be costly to correct.
Points to remember:
1. Position the panel where it is to be installed
2. Ensure devices are surveyed for their exact positions touching the ceiling or wall. A few inches
either side may affect the signal strengths substantially.
3. In order to have an accurate survey the batteries in the survey detector should be changed at
least once a year
