About External Siren Replace
External siren replace swaps a failed, faded or constantly tampered bell box so the intruder system can still warn outside the building. iComply fits a siren matched to the panel, with a working tamper and strobe, for homes and commercial frontages across the North West.
We check why the old box failed — battery, tamper switch, cable, or water in the cover — before fitting a replacement. The strobe and sounder are proved from a test activation, not left assumed. This is the alarm bell box, not a CCTV speaker or an access-control door buzzer. Price on application after a survey. We do not publish a pound figure for this visit.

External Siren Replace FAQ
The bell box is silent but the keypad still beeps. Do I need a new panel?+
Not always. A dead external siren, flat bell battery or open tamper is common. We test the output before condemning the panel.
Will a new siren stop false alarms?+
It restores the external warning. If the system is tripping falsely, that is a separate zone fault and we will say so on the visit.
Can you hide the siren for aesthetics?+
The box still needs a sound path and a tamper. We agree a practical position on the elevation rather than burying it where it cannot be heard.
