I recently put together a demo setup for my Simplex 4020 with the 4003 voice panel!
There are some unique features on the 4003 that are exclusive to the 4020, namely spoken walk test messages. I also have coded pull station support, various annunciators, and a mix of conventional/addressable devices on this panel. I aimed to have my 4020 contain a variety of features and components (special thanks to Nicsou and @4903-9222 for programming this for me). I’m very happy with how this turned out!
System Components:
- Simplex 4020 Fire Alarm Control Panel (dated 1995, ver. 7.02; older but works fine)
– Includes 2 expansion I/O cards, as well as a network card (unused).
– Current layout has 8 conventional zones, 3 NACs, and 9 relays. - Simplex 4003 Voice Control Panel (dated 1999)
- Simplex 4602-9102 Annunciator
- Simplex 4603-9101 Annunciator
- Simplex 4263-1 Coded Pull Station
- Simplex 2099-9795 Mapnet II Pull Station
- Simplex 4098-9716 Ionization Smoke Detector
- Simplex 4098-9701 Photoelectric Smoke Detector (x2, on different bases)
- Simplex 4098-9731 Heat Detector
– Detector bases are 4098-9781s and a 4098-9785. - Simplex 2190-9153 Mapnet II Class A Monitor ZAM (not working, using as a junction box)
- Simplex 4090-9101 IDnet Class B Monitor ZAM (substitute for 2190-9153)
- Simplex 2099-9754 (with institutional cover)
- Simplex 4903-9148 Speaker/Strobe
- Simplex 4051 Horn + 2904-9001 Light (for coded pull station zone)
- Honeywell SC7156-1027 Chime/Strobe (basically a Wheelock CH70)
- Simplex 2098-9808 Remote LED
There are a few more things to work on for the 4020. First would be to get a cabinet for it. I’ll likely use my 4002 cabinet since both panels can use it. Next would be to implement priority 2 alarm points. We tried to do this with a security point but it didn’t seem to work. Lastly, update the firmware on the 4020 CPU. It’s old and buggy; updating it would fix such issues and provide more options to the system.
