2. Minimum signals i.e. burglary and panic must be monitored separately.
3. All detection zones to use end-of-line or double end-of-line resisters and must be correctly terminated.
4. All detectors must be screwed down. Glue or double-sided tape is not permitted.
5. The mains transformer must be a minimum of 30VA. The cable from the transformer to the control panel must have a minimum core diameter of 0.5mm. (Cabtyre or Ripcord)
6. The standby battery must have a minimum capacity of 7.0 aH and be of the sealed type or have a minimum standby time of 6 hours for any part of the system.
7. A maximum of 2 (two) electronic detection devices may be connected on a zone, except in zone doubling, then 1 electronic detector only on each zone.
8. A maximum of 5 (five) magnetic contacts may be connected on a zone, except in zone doubling, then 1 magnetic contact only on each zone.
9. All joints must be soldered and insulated or in a junction box.
10. The radio transmitter and antenna must be correctly mounted to manufacturers specifications. The DC power cable from the Radio transmitter to the control panel to have a minimum core diameter of 0.5mm. (Cabtyre or Ripcord)
