Step 7: Confirm signal strength
Test signal strength using the appropriate
Installer option, as described in your

SIGNAL STRENGTHS
Int. SNDR 01 9(8)
In this example, the reading is 9, with a
lowest recorded value of 8.
A reading of 9 is the highest. 5 or
above is good, 3 to 4 is marginal and 2
or below is not acceptable.
The value is updated when the tamper
switch changes state, the external
supply is switched on or off, every 10
seconds when the sounder is making
a sound, and every 4 minutes at other
times.
If you wish to test sounder operation,
choose
Test, Sirens & Sounders, Internal
Sounders.
