I have just attempted to replace the alarm bell in the house as the old box had a failed battery.

I have a Countess Alarm panel (circa 1990) made by Racal. The manual shows different connections to the new bell (Reson8). The panel installation manual shows

-ST

+

S-

H-

-

R

Please can someone give me some clues to how this relates to the Reson8 connections of

STB-

TRIG-

HOLD OFF-

HOLD OFF+

RTN-

Many thanks in advance!

STB- = -ST

TRIG- = S-

HOLD OFF- = -

HOLD OFF+ = +

RTN- = R

although on some you would connect the R to tamper feed at the bell and link RTN to - hold off.

that seems to be right to me, not sure what the H- is for.
