X-DA High-Efficiency Power Amplifiers are High-Efficiency Power Amplifiers with 24 V DC Backup Power Supply conforming to international voice alarm standards which is the perfect choice for safety-required applications
When a fault, self-protection, or self-testing happens, its audio input fault port on the rear panel will short circuit, and a fault signal will then be sent to the control unit in the network. When a shout circuit is detected in the main power supply circuit, the power will be automatically shut down. The backup power supply will then be enabled to replace the main one. The device adopts a lightweight design. The front panel is made of UL94V-0 fireproof ABS material, protecting the machine under extreme conditions. A cooling fan is equipped for heat exhaustion so that the machine can maintain high working efficiency. The amplifier can work without main power in an emergency

EPS40 Series supervisory pressure switches are designed for use in dry pipe systems or pressure tanks and water pressure supplies of automatic water control valves. The EPS40-1 has a single SPDT switch, while the EPS40-2 model contains two SPDT switches. The EPS40 Series features field adjustable pressure sensitivity to provide an alarm response between 10 and 100 psi. All models are factory set for use in a nominal 40 psi system. The EPS40-1 is factory-set to respond at 30 psi at decreasing pressure while the EPS40-2 is factory-set to respond at 50 psi on rising pressure and 30 psi at decreasing pressure. The pressure adjustment wheel requires no special tools and does not affect switch synchronization on the EPS40-2. The EPS40-1 and EPS40-2 supervisory pressure switches are NEMA 4 rated.
Features & Benefits:
– Sensitivity adjustment wheel, no special tools required
– Reinforced diaphragm resists pressure spikes
– Two conduit entrances
– Both one- and two-switch models are available
