the bypass switch. The remote switch’s NO terminal then connects to the DC negative lock return wire so that the remote switch will release the lock by connecting the negative side even when the panel is bypassed. If there is a lock status sensing switch, it connects as in type 2, Figure 4.

6. USE OF MULTIPLE PANELS

It is often a requirement that more than one LCP is employed to control and monitor the same group of doors. This can be done in several different ways depending on the control that is desired. The Sections below discuss the options.

6.1 “MASTER/SLAVE” PANELS (FOR FAIL SAFE LOCKS)

With this connection scheme, the switches are placed in series while the monitoring lights are in parallel. In the “normal” (secure) condition, the zone toggle on each panel is up. Either toggle can release the lock but the toggle that released the lock must be used to resecure it. Note that this set-up is well suited for momentary toggles. Since the switch is spring loaded, it is automatic that the switch that released the lock resecures it. Wiring for a two panel “master/slave” installation is shown in Figure 15. The terms “master” and “slave” do not imply that there is any difference in the boards (or panels). It is just a way of identifying the board which connects to the power supply (the master) and the one that connects to the equipment at the doors (the slave).

Note the connections between the red flying leads and the “R” terminals. This merely permits either panel to be able to reset a system violation alarm.

If more than 2 panels are used, the “master” board connects with any number of slave boards. Referring to Figure 15, the master board and 1st slave board connect as shown. The 2nd slave board would connect to the 1st slave board with the E and S terminals wired together and with the L terminals of the first slave board connecting to +1, +2, +3 and +4 of the second. This continues the series lock power connection. The locks always connect to the last slave board.
