A 3-position plug provided in the Model 4210 hardware kit is used to connect 16–28 AWG wire to the ALARM terminal block (see Table 1-3, Contents of Hardware Kit Shipped with the GranDSLAM 4200,

Tin Chapter 1, Installation).

Models 4220 and 4230 – The ALARM interface for the Models 4220 and 4230 consists of five contacts. Three of the contacts provide access to alarm relays that that can be used to set off Major and Minor physical alarms. The other two contacts provide access to a sense circuit that can be used to detect the open or closed condition of an external alarm relay. See Figure 2-1, Alarm Connection Example, for an example of how to connect a Model 4220 to a Model 4210 so that the Model 4220 can monitor the state (open/closed) of the Model 4210’s major alarm.

A 5-position plug provided in the Model 4220 and Model 4230 hardware kit is used to connect 20–28 AWG wire to the ALARM terminal block (see Table 1-3, Contents of Hardware Kit Shipped with the GranDSLAM 4200, in Chapter 1, Installation).
