Internal sounder are a useful addition to any burglar alarm system. Piezo sounders are relatively inexpensive and will effectively disorientate an intruder inside your property.
Piezo sounders replicate the external sounder and are connected in parallel to the external sounder circuit. Extension speakers replicate the existing internal speaker or in the case of blank end-stations the tones orf the RKP (Remote Keypad).
These Piezo electronic sounders are designed to be fitted internally and connect into the same circuit as the external sounder in a burglar alarm system and as such behave in the same way. They are a useful deterrent in that the intruder is disoriented by the loud noise inside the premises. They are available as a simple unit - Sound bomb I and II or in more attractive cases with in some cases integral strobe lights. In general they should be fitted away from the control panel so as not to indicate where the control panel is situated.
All major burglar alarm control panels have the facility to connect an internal extension speaker or in the case of a stand-alone control panel (where one is usually already fitted in the panel) to add an additional speaker. The speaker replicates the tones given by the existing speaker or those of the remote keypad - if fitted. They must be fitted to the dedicated speaker terminals on the panel and NOT to the external sounder terminals.
Sirens are electromechanical devices which are significantly louder than the more common piezo sounders. They find use in larger premises such as warehouses. The Masterblaster has an extremely loud sound output of 127dB - the hearing pain threshold is 120dB. The Masterblaster is a mains-operated device with an integral 12v relay which allows it to be fitted to any hard-wired burglar alarm control panel.
The house has a Veritas R8 installation with a RKP, which has the following info on the PCB D0129-02.01 (C) Texcom 1999. I replaced the lead acid backup battery July 2012. There is an external ‘Flash Guard’ Strobe/Sounder fitted with the original installation, circa 2001. I now want to replace the battery in the ‘Flash Guard’ unit. I am unable to determine from ground level, whether it is a XL plus or 100T model? Would you please advise how to replace the battery for either model?
I am getting false alarms on my burglar alarm, at night at 1 30 am, 3 times now. it has been suggested I fit one of your ACT Meters 12v Spike Suppressor, is this fitted in between the red positive cable to the battery and earth please.
Lee, I have successfully added an LCD remote keypad to my Optima Compact G4 but the exit beeps now only work on the RKP. Even if I set the alarm from the main panel the beeps still only work on the RKP. Is this normal? Is there any way I can alter the system settings so the beeps are on both the main panel and the RKP?
I came across your site and have found your articles very useful in deciding which alarm system to go for. I'm thinking of buying the Texecom Premier Elite 48 'kit' and taking my time installing myself, I just have a couple of quick questions...
- I'm conscious this system is aimed at the professional installers but will the kit be supplied with engineers manual?
- on the Texecom website there's an option to download the wintex and other software for connecting to computer but you need to register as an 'installer' to download them - I've not tried registering but just wondered if you know whether it's possible to download/use the software if you're not an 'installer' as such but own their system.
I bought the Accenta G4 and an Odyssey 1/1E from you and am trying to connect them. The problem I have is that the terminals have different names and I can't work out what goes to what. The G4 has T, A, D, B and Strobe neg. The Odyssey has A, B, C, D and S. Confused! Please help.
