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 vibrating pager units. 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 2002 & EN54-2 and MUST be

installed by a competent person as defined in BS5839-1 2002.

Installation Training

Installation training is available; please call us on 01246 450789 for more details.

INSTALLATION

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 unswitchable 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 12 Volt lead acid 7Ah back-up battery (Yuasa Type NP7-12)

Dimensions

(H100mmxW150mmxD65mm). 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

The top terminal block on the main PCB has a RED and BLACK wire secured to the outer two
terminals. The BLACK wire SHOULD NOT BE REMOVED. The RED wire must be removed and

rerouted via a relay in an Input / Output Module. In alarm mode this VOLTAGE needs to be

removed in order to trigger the Fire Safe Interface, therefore a normally closed contact will be
required. The terminal is clearly marked GND (top/ BLACK wire) and V+ (bottom/ RED wire).

It is also possible to trigger the unit by the removal of an external voltage. IF AN EX

TERNAL
VOLTAGE IS USED THEN BOTH THE RED AND BLACK WIRES MUST BE REMOVED FROM
THE TOP TERMINAL BLOCK AND INSULTATED OR THE MAIN PCB CAN BE SERIOUSLY
DAMAGED. The Interface Panel requires an external voltage of at least 5v AC or DC the maximum

voltage must not exceed 30v AC or DC.
