TECHNICAL SPECIFICATION

Introduction

The Silent Alert Fire Safe system alerts people who are deaf when a fire alarm is activated; it
comprises a fire alarm interface and one or more compatible receivers. The fire alarm interface
links to a fire alarm panel via a volt free relay and incorporates a radio transmitter. When the fire
alarm is activated the transmitter within the fire alarm interface sends out a coded radio signal.
When a Pager receives this signal it vibrates and lights a fire key on the Pager display. The
system is designed to comply with all relevant parts of BS5839-1 2013 & EN54-2 and MUST be
installed by a competent person as defined in BS5839-1 2002.

Preliminary radio coverage test

A preliminary radio coverage test is normally conducted prior to installation to ensure total
coverage throughout a building. It is recommended that a further radio coverage test is
performed prior to permanently securing the Fire Safe panel to a wall in case it needs to be
relocated. The Fire Safe panel should be mounted temporarily to a wall at between 1.5 and

1.75 meters from the ground away from large metal objects and lift shafts. For best results
locate the panel central to the building. In multi-storey buildings penetrations through steel
re-enforced concrete floors may be poor. In these situations coverage would be improved if
the panel is located one floor above ground level to provide coverage over three floors or
two levels above ground level to cover four floors. In-building coverage will vary from
building to building therefore it is essential that a full and thorough radio coverage test is
conducted. The range test procedure detailed later under the heading Site Survey should
be followed. If it is found that the coverage is inadequate then additional Fire Safe interfaces
may need to be added. In this case it will be necessary to change the signal patterns for
each panel to ensure there are no standing wave problems. This aspect is covered in more
detail under the heading The use of more than one Fire Safe panel below.

Power Supply

It is necessary to supply the Interface Panel with a dedicated mains supply (220-240v AC 50
Hz) via its own un-switchable fused spur. The mains terminal block is located at the bottom left
hand side of the main PCB and is marked Earth (top) Neutral (middle) Live (bottom). The Panel
will also require a 6 Volt lead acid 4Ah back-up battery Type Y4-6 (Dimensions
H100mmxW47mmxD70mm).
It is necessary to connect the battery to the two wires with crimped connectors, before
connecting the mains to avoid a fault condition.

Alarm Output from main fire alarm panel

It is possible to trigger the unit by the removal of an external voltage using the bottom I/O
terminal.
The Interface Panel requires an external voltage of at least 5 – 30V AC
or DC.
NOTE the maximum voltage must not exceed 30v AC or DC or damage
will occur to the panel invalidating warranty.

Fault conditions from Fire Safe panel

The Fire Safe panel has a fault output to the main fire alarm panel
provided via the top terminal block. A fault condition on the Fire Safe
panel will cause a relay to be closed that will create an open circuit
between common and normally closed (N/C) and a closed circuit
between normally open (N/O) and common.

A fault alarm will be given in the following conditions:

 Mains failure
 Battery charge failure or removal
 Loss of radio signal

 Main PCB failure
