Control Unit & Enclosure (P/N 23826)
The Amerex STRIKE ECS Control Unit is an alarm initiating and release unit designed to function
without external power. The Control Unit utilizes two non

rechargeable batteries as a primary and
secondary (backup) power supply
and will sustain itself for up to six months. The Control Unit and
batteries are housed within a protective stainless steel enclosure that can be mounted to a wall or
surface. The enclosure features a hinged, lockable door for internal access. All field wiring enters
the enclosure through electrical knockouts and terminates to the labeled terminal boards on the
Control Unit. Enclosure dimensions and features are shown below (See Figure 2.7.1a), along with
an open enclosure (See Figure 2.7.1b). Control Unit front face indicators and features are also
shown on the following page (See Figure 2.7.2/Table 2.7.2). All dimensions are in inches [mm].
