Site survey
Radio coverage test
1.
Ensure the Fire Safe is in range test mode. Engineer’s key 4 in the on position.
2. Ensure the Pager is charged and in range test mode, as above.
3. Walk around the building with the pager. As the pager receives a poll signal, the keys on
the pager will light. The highest signal strength will light the telephone key the lowest the
battery key. It is essential that one of the keys lights up during each transmission, within
the area to be covered.
4. It is possible to add additional Interface Panels on larger sites.
5. Sw
itch Engineer’s Key 4 on the Fire Safe Interface to the OFF position.
6. Move key B to the OFF position, the fire key will flash every 7 seconds to show it is now
in Fire Safe mode. If the Pager fails to receive a polling signal from the Fire Safe system
it will flash all the keys and vibrate 6 times to indicate it is out of range.
The use of more than one Fire Safe Panel
In larger buildings it may be necessary to have more than one Fire Safe Interface Panel. In this
case it is important that the timing of the fire alarm radio signals are altered to avoid standing
wave problems. A standing wave is where two radio waves meet at similar power levels and can
have the effect of cancelling each other out. It is necessary therefore to overcome this
phenomenon by ensuring that adjacent Fire Safe Panels do not send radio signals out at the
same time. This is achieved by changing the ON / OFF periods as shown below.
Poll Signals
The Fire Safe Panel sends a poll signal once every 4 minutes 45 seconds. This is a radio signal
integrity check. The pager will expect a poll signal at least once every 5 minutes. If a signal is
missed due to a fault, then the Pager will vibrate and all keys will flash six times. This will occur
every five minutes whilst ever the fault remains. The Fire Safe Panel includes its own radio
receiver to check the radio signal, using the same poll signal. If a poll signal is not sent the Fire
Safe Panel will send a fault to the Fire Alarm Panel
.
Daily Use
The Pager can be placed at reception on charge permanently. Both the Fire Safe Charger and
Alarm Clock Charger have intelligent charging circuits that ensure the Pager is not overcharged.
If a visitor leaves the building without returning the Pager to reception the Pager will vibrate and
all lights will flash 6 times within 4 minutes 45 seconds to remind the user. This sequence will
repeat whilst ever the Pager is out of range of the system.
